After selecting the Create New Point Feature popup menu option, you can proceed place the point feature by left clicking at the desired location of the point. You can cancel creation of the new point at any time by pressing the Escape key.

You can also use the Create New Point Feature at Specified Position option to create a new point feature at a manually specified location. When you select this option, a dialog appears allowing you to enter the location for the new point feature in either latitude/longitude coordinates or coordinates in the current view projection.

After selecting the Create Range Ring(s) popup menu option, you can proceed to place the center location of your range rings by left clicking at the desired location. If you had point features selected when you selected this option you can also choose to create the rings centered on the selected point feature(s) rather than manually specifying a center location. You can cancel creation of the range ring(s) at any time by pressing the Escape key or right clicking. If you choose to create new range rings at selected point locations and those points have a RING_RAD_M attribute, that attribute value will be interpreted as the ring radius in meters and used rather than what is specified in the dialog described below.

After selecting the center of your range ring(s), the Select Range Ring Parameters dialog (pictured below) appears and allows you to setup how many range rings you would like to create and how far apart you would like to create them. You can choose to create rectangles with the specified range as the radius rather than a ring if you would like. You can also choose to create a "multi-ring". Checking this box will delay the actual range ring creation until you have added additional range rings and unchecked the box. Then all rings in the "multi-ring" will be combined if possible to build nice looking combined range rings.

Once you have completed have completed creating the range ring(s), the Digitizer Tool will remain in the range ring creation mode, so you can simply left-click to create additional range rings centered on another location, or right-click to choose a different mode.

The range ring feature has numerous applications, including search-and-rescue and aviation.

After selecting the Create Buffer Areas Around Selected Feature(s) option in the Advanced Feature Creation popup menu, the Setup Buffer Areas dialog (pictured below) appears and allows you to setup how many buffer areas that you want to create around each selected feature and at what distance to space them. For example, if you want to create buffers at distances of 100, 200, and 300 meters around each selected feature, you would specify that you want to create 3 buffer areas with a buffer distance of 100 meters. You can also select to get the base buffer distance from an attribute of the selected features rather than using a single fixed buffer radius for each feature. That attribute value can also include unit text, like '500 m' or '300 ft' and that will automatically be recognized and used. If you would like to combine all overlapping buffers into larger combined areas, simply check the option to Combine Overlapping Buffer Areas. To create buffers some distance inside a selected area feature rather than outside of it, simply specify a negative buffer distance.

Once you have completed have completed creating the buffer areas(s), the newly created areas will automatically be selected so you can easily right-click to edit them, display measurement information, etc.

Under the Create Area Shapes and Create Line Shapes right-click popup menus you will find options to create Arc, Circular, Elliptical, Rectangular, and Square area and line features. For all of these shape types (except the rectangular/square option where you manually enter the coordinates), you click and hold the left mouse button at the center of the feature, then drag it until it is of the desired shape. For Circular/Elliptical features and Arcs, the default shape follows a circle and holding down the SHIFT key will dragging will result in an ellipse. For Rectangular/Square features, the default shape is a rectangle and holding down the SHIFT key will force the dragged shape to be square. If you hold down the 'T' key when left clicking to start the shape, the start point will be treated as the top left corner of the feature rather than the center of the shape feature.

If you choose the 3-point area or line rectangle creation options, you enter a special mode for easily drawing rotated rectangles. Just left click to start the rectangle, then left-click again at the end of the first side, then left click again when the rectangle shape is what you want to create it.

After selecting the Create Strike-and-Dip Point popup menu option, you can proceed to select the location of your new point by left clicking at the desired location. If you drag the cursor in the direction of the strike then release it, the point will be placed at the start of the mouse drag and the strike/dip azimuth will automatically be initialized to the direction that you dragged. You can cancel creation of the point(s) at any time by pressing the Escape key or right clicking.

After selecting the locationof your strike-and-dip point, the Enter Strike-and-Dip Parameters dialog (pictured below) appears and allows you to setup your point. This includes selected the azimuth angle for your strike, either relative to True North (the default) or to the top of the map screen, the dip value for your point (which will be used as the display label on the map), the symbol to use, an optional description, and which layer in the Control Center to place the new point feature. There is also a Modify Location button which allows you to fine-tune the location of the point by manually entering coordinates.

Once you have completed have completed creating the strike-and-dip point, the Digitizer Tool will remain in the strike-and-dip creation mode, so you can simply left-click to create additional points centered on another location, or right-click to choose a different mode. If you hold down the Ctrl key when left-clicking to create additional points the new strike-and-dip point will automatically be created at the clicked location using the same parameters as the last strike-and-dip point that was created, allowing you to quickly place a lot of points without going through the dialog each time.

After selecting the Create Regular Grid of User Specified Size/Orientation popup menu option, you can proceed to select the anchor point (top left corner) of your grid by left clicking at the desired location. You can cancel creation of the point(s) at any time by pressing the Escape key or right clicking.

After selecting the anchor point for your grid, the Grid Setup dialog (pictured below) appears and allows you to setup the size, count, naming, and orientation of your grid cells. Pressing the Anchor Point button allows you to edit the location of your anchor point. You can also choose to create lines rather than areas and to create points at the grid edges if you want, which is useful for creating your own labeled grid over the map for just a certain sub-area.

In addition to creating new vector features, the Digitizer Tool is also very useful for editing existing vector features. This tool provides the ability to move, delete, and reshape vector features, as well as modify the label, classification, drawing style, and attribution of any vector feature loading from any file format supported by Global Mapper. Note than any edits made are NOT automatically saved back to the origin file, but they will be saved in Global Mapper workspaces and into any exported vector files.

Before you can edit an existing feature or features, you first must select them. Once a feature is selected, you can tell that it is selected because it will be drawn with a different style. The different methods for actually selecting features are described below.

One way to select features is by simply by clicking the left mouse button near the feature, or in the case of area features, within the feature. Using this method, the closest point or line feature will be selected, or if no point or line features are nearby and you clicked within an area feature, the area feature will be selected.

To select multiple features at a time, you can drag a selection box by holding down the left mouse button to draw a box. Any features entirely within the box drawn or features which are cut by the box will be selected. If you hold down the 'I' key while dragging the box, only features and vertices that are completely within the box will be selected. This is useful for things like selecting a point feature that is on top of a line/area border.

You can add to an existing selection by holding down the CTRL key while performing a selection with any of the above described methods. You can deselect features by holding down the SHIFT key while performing a selection. You can toggle the selection state of features by holding down both the SHIFT and CTRL keys while performing a selection. As a final option, holding the 'P' key when clicking to select the feature may be used to select the topmost area feature at a location. This is useful for selecting area features that may be overlaid by a line or point feature. It's functionally equivalent to using the Vector Display tab of the Configuration dialog to enable only the "Select From Areas" option - a temporary selection filter.

If you are planning on moving lots of features, you can speed up the process by holding down the ALT key when selected features and/or vertices. Doing this will cause you to automatically put into move mode when selecting new features and/or vertices.

You can also select area, line, and point features within selected area features by first selecting one or more area features using the previously described methods, then right clicking and selecting the appropriate option under the Advanced Selection Options submenu. This makes it easy to find and edit all of the point, line, and/or area features within some other area feature(s).

When working with island and parent areas, there are also some options available under the Advanced Selection Options submenu that make it easy to select all of the island areas associated with selected parent areas and to also deselect the parent area for a selected island area. You can also select lines or points within selected areas, or also select any area that share a vertex with the selected area(s) or any areas that they were connected to, or select any line features that share a vertex with the selected area(s).

If the Show Area and Line Vertices option is enabled (Shift+V is a keyboard shortcut to toggle this setting), you can also select individual vertices on area and line features. You must select vertices before options allowing you to work with individual vertices in area and line features appear in the right-click options menu. Selected vertices will be shown on the display with a circle around them.

To select vertices, simple left click near a vertex to select the closest one if any are nearby, or drag a box to select all vertices within the box. The same behavior modifications occur as described above if the CTRL and/or SHIFT keys are pressed when selecting. If you hold down the 'S' key when left clicking, only vertices from already selected lines or areas will be considered.

Pictured below is a screen capture showing a line feature and several of its vertices selected, with a right-click popup menu opened to show the available options.

When a single area, line, or point feature is selected, there is an option on the right-click popup menu allowing you to edit that feature (i.e. Edit Area Feature, Edit Line Feature, or Edit Point Feature). Selecting that option displays the Modify Feature Info dialog which allows you to modify the Name, Feature Type, Drawing Style, and Attributes for the selected feature. You can also access this dialog by double-clicking on a feature. A sample of this dialog for an area feature is below.

The Name field allows you to modify the display name of the feature. If you are editing or creating a road feature, you can set the name to a commonly supported iconized road name (like I-35 or US40) and when you press OK you will be prompted whether or not to display an icon for the road name. This allows you to generate a nice iconized display for most highway types. If you would like to split point and area labels up onto multiple display lines, you can add the newline escape sequence (\n) to your display label. You will then be prompted to split your label onto multiple lines when you save the changes.

If editing an area or line feature, the Vertices button will appear allowing you to edit the vertices of the selected feature, including working with per-vertex elevations for 3D features.

The Feature Type selection allows you to choose which Global Mapper classification to assign to the feature. You can also choose to create a new Global Mapper type with the Create New Type button.

The Feature Layer selection allows you to choose which layer that the feature should be assigned to. You can choose an existing layer, the User Created and Modified Features layer, or you can create an entirely new layer to add the feature to. A layer corresponds to a single entry in the Control Center.

When you have one or more features selected, you can right click and select the Rotate/Scale Selected Features command to bring up the Setup Rotation and Scaling dialog (pictured below). This dialog will allow you to rotate and scale the selected features about a point that you select. If you choose the option to drag to the map to rotate, you will enter rotate mode after pressing Ok on the dialog and can then hold down the left mouse button and drag around to rotate the image graphically to setup the desired position.

You can combine overlapping or adjacent area features into a single area feature by first selecting the area features to combine, then selecting the Combine Selected Area Features right-click menu option. Any areas that are succesfully joined into a new one will be marked as deleted.

You can combine multiple line features into a single line feature by first selecting the line features to combine, then selecting the Combine Selected Line Features right-click menu option. This option will connect any lines that you have selected that join at an endpoint. Any lines that are succesfully joined into a new one will be marked as deleted.

When you select the option you will be allowed to setup options for the combine operation, including whether or not the attributes of the lines have to much to be combined, if the lines being joined have to fully close, and whether or not to create multiple areas if the selected lines don't all form a single path.

You can find the intersection of two area features by selecting both features, then right clicking and selecting the Find Intersection of Selected Area Features menu command. This operation will create a new area feature from the intersection of the two selected area features. You will also be prompted to create new area features from what is left outside of the intersection. If you choose this option then the original area features will be marked as deleted once the operation completes successfully.

You can cut one area feature shape out of another area shape, either adjusting the second areas outer boundary or making the first area feature become an island, or hole, within the second area by first selecting the area(s) that you want to cut from another area/make into an island, then right click and select the Cut Selected Area(s) from Another Area (Add Islands) menu option. You will then need to left-click in the area feature that you would like to cut the selected area(s) out of.

You can split an existing area feature into two new area features by selecting the two vertices across which you would like to split the area, then right clicking and selecting the Split Selected Area at Selected Vertices menu option. This will generate two new area features by splitting the selected area feature across the segment between the two selected vertices. Note in some situations you will get invalid areas or no result at all, so be careful to select vertices for which the connected segment does not cross outside of the area or intersect any island areas.

You can crop any loaded features to one or more selected area features by first selecting the area feature(s) to crop to, then right-clicking and selecting the Crop Loaded Features to Selected Area(s) option. This will display a dialog allowing you to choose which types of features to crop, whether or not to mark the original features as deleted, and what layer to put the cropped results in. Note that any features that are completly enclosed in the cropped area and thus not cropped will just stay in their original layer.

You can crop or split selected line features to a selected area feature by right-clicking and selecting the option to Crop/Split Selected Lines to Selected Areas. This will delete any portion of the line feature that lies outside of the selected areas unless you select the Split option, in which case separate lines will be created for the parts inside and outside the selected area feature(s). Note that the original line will remain available as a deleted feature, so you can recover the original line if needed.

You can split selected area features to a selected line feature by right-clicking and selecting the option to Crop Selected Area to Selected Line. This will split the area feature along the selected line boundary. If the line doesn't extend all the way to outside the area, it will be extended to the area bounding box. Note that the original area will remain available as a deleted feature, so you can recover the original area if needed.

You can automatically move selected point features to the nearest point on the selected line feature(s) by selected both line and point features, then right-clicking and and selecting the option to Move Selected Point Features to Selected Lines.

During some operations (i.e. drawing new area or line features or graphically placing a new point feature), the cursor can automatically snap to existing features when you move it near them to facilitate lining up features. This happens by default unless the ALT or V keys are depressed. Pressing the ALT key causes no automatic snapping to occur, while pressing the V key causes only vertices on existing features to be snapped to. Holding down the P key causes only nearby point features to be snapped to.

When drawing new area or line features or moving existing features, you can use the CTRL and SHIFT keys to cause the next vertex to be snapped vertically or horizontally relative to the last vertex or moved vertically or horiztonally compared to the features current location. Hold down the CTRL key to snap vertically, the SHIFT key to snap horizontally, or both the CTRL and SHIFT keys to snap diagonally.

During some operations, like drawing new features, you can undo your last placed point by pressing Ctrl+Z.

Depending on what types of feature are selected and what data is available, additional options may appear on the option menu that appears when right clicking. These additional options are described below.

If gridded elevation data (i.e. DEMs) is loaded and at least one feature is selected, the Calculate Elevation/Slope Stats for Selected Feature(s)... option will appear when right clicking. Selecting this option will examine the loaded terrain within the selected area feature(s) and, if terrain is found within a selected area, add MIN_ELEV, MAX_ELEV, AVG_ELEV, STD_DEV_ELEV, MAX_SLOPE, AVG_SLOPE, and STD_DEV_SLOPE attributes to the area containing the minimum, maximum, average, and standard deviation of elevation values encountered within the area feature as well as the maximum, average, and standard deviation of the slope values (in degrees) found within the area. For selected line features, the maximum and average slope (in degrees), the total elevation gain and loss along the path, and the maximum slope both up and down the line (assuming travel from the start of the line to the end) for the line will be computed and added as MAX_SLOPE, MAX_UP_SLOPE, MAX_DOWN_SLOPE, AVG_SLOPE, ELEV_GAIN, and ELEV_LOSS attributes. For selected point features, the ELEVATION, SLOPE, and SLOPE_DIR attributes will be calculated and added for each point that is on a loaded terrain surface.

!!!This functionality is only available in the Global Energy Mapper product!!!

You can easily insert a complete pad site template, or really any object template, by right-clicking and selecting the Insert Pad Site from Library option. When selected this option displays the Select Pad Site dialog (see below). This dialog allows you to choose which pad site template to insert. There are several pad site templates included with the installation. You can press the Add Pad Site from File button to add a new template object to the library from any supported vector format, like a DXF or DWG file. When you press the OK button the group of objects is inserted at the clicked location and is automatically selected for easy moving, scaling, and rotating.

!!!This functionality is only available in the Global Energy Mapper product!!!

If one or more area features is selected and terrain data is loaded, the Advanced Feature Creation submenu will contain the Calculate Flattened Site Plan Grid from Selected Area(s) option. When selected the Setup Site Flatten Parameters dialog (pictured below) appears, allowing you to setup the site flattening operation. You can specify the height to flatten the areas to or allow a height ot automatically be calculated that results in an approximately equal amount of terrain needing to be cut as needs filled so little or no haul-in or out is needed. You can also setup the allowed slope from the site edges to the terrain surface as well as what width and vertical separation of benches/terraces to use if required.

The images below show the 3D viewer before and then after performing a flattening operation on a hillside:

The images below shows the 3D viewer after an operation to flatten a site high above the terrain surface, mainly to illustrate how the terracing works. Note how the new surface matches up with the original terrain surface:

If one or more area and/or line features are selected, the Add/Update the Measure Attributes of Selected Feature(s) option will appear when right clicking. Selecting this option will add measurement attributes to the selected features that do not already have them, or update the measurement attributes of features that do. The measure attributes include LENGTH for lines and PERIMETER and ENCLOSED_AREA for areas.

In addition to adding/updating the measure attributes for the selected feature(s), the combined length and/or enclosed area of the selected line and area features will also be reported by this command.

You can also select the Display Feature Measurements option to display a dialog (pictured below) listed the measurements and attributes of each selected line and area feature as well as the total combined enclosed area and perimeter/length of the features. This dialog also allows you to easily export the results to a CSV file.

If two of more line features are selected, the Insert Vertices and/or Split at Intersections of Selected Features option will appear when right-clicking. Selecting this option will find all intersections between selected line features and allow you to insert new vertices in the selected lines at the intersection locations if there are not already vertices at the intersection and or split the lines at any intersection or only existing at-vertex intersections.

This is a very powerful command allowing you to make a line network have node-to-node connectivity and even make sure that lines terminate at intersections if required for your application. This is commonly used for making routable street maps.

If two of more line features are selected, the Find Non-Connected Line Endpoints option will appear when right-clicking. Selecting this will display a dialog allowing you to either mark all line endpoints that do not connect to an endpoint (not an interior vertex) of another selected line or those line endpoints that don't connect and are within some distance of another selected line endpoint. This is a very useful feature for allowing easy identification and fixing of connectivity issues within loaded vector data.

Any line endpoints that do not connect based on the selected criteria will be displayed with a blue circle over that endpoint. Once you think you have fixed the connectivity issues at a location, simply re-run the command to find the non-connected line endpoints to update the display of the blue circles (they are not automatically updated as you join line endpoints).

If two of more point features are selected, the Find Selected Points Within ??? Meters of Other Selected Points option will appear when right-clicking. Selecting this will display a dialog allowing you to specify a search distance. Any selected point features that are within the specified search distance of another selected point feature will be displayed with a blue circle over that point. If you delete or move some points to remove duplicates (the primary use of this tool), simply re-run the command to find the to update the display of the blue circles (they are not automatically updated as you edit the data).

If one or more area features are selected, the Advanced Feature Creation Options->Create/Flatten Terrain from Selected Area Feature(s) option will appear when right-clicking. Selecting this option will allow you to create a new elevation grid covering the selected area features that has all points within the selected area feature(s) set to the elevation of those area features. Any portions of the new elevation grid outside of the area features will be set to invalid, allowing any underlying terrain to show through. If you also select the option that elevations are relative to the height of any underlying terrain, the new terrain surface will have heights equal to the original height of the terrain at each sample location within the area offset by the elevation value of the area feature. This functionality is useful for adjusting all elevation values within an area by some amount (the area elevation).

This feature provides a very easy way to do things like flatten an area, like a lake, in underlying terrain layers. Just assign an ELEVATION attribute to your area feature, then select it and choose this option to flatten everything inside that area to the elevation attribute value. This is also a nice way to create an elevation grid representing a city-scape from building outlines with ELEVATION attributes.

If one or more point features are selected, the Add Address Information from Roads to Selected Point(s) option will appear when right-clicking. Selecting this option will cause each point to be examined to find the nearest line feature, and, if it contains addressing information, for the address of the nearest point on the line to the point feature to be stored as address attributes with the point feature. A dialog will appear to prompt you for how far from each point that you want to search for a line feature with addressing information.

The following attribute names for line features are recognized as containing address information:

• FR_ADDR_R, R_FROM_ADR - starting address number on the right side of the road
• FR_ADDR_L, L_FROM_ADR - starting address number on the left side of the road
• TO_ADDR_R, R_TO_ADR - ending address number on the right side of the road
• TO_ADDR_L, L_TO_ADR - ending address number on the left side of the road
• PLACE_R, R_CITY - city or town on the right side of the road
• PLACE_L, L_CITY - city or town on the left side of the road
• STATE_R, R_STATE - state or province on the right side of the road
• STATE_L, L_STATE - state or province on the left side of the road
• ZIP_R, R_ZIP, R_PCODE - postal code on right side of road
• ZIP_L, L_ZIP, L_PCODE - postal code on left side of road
• COUNTRY_R, R_COUNTRY - country on right side of the road
• COUNTRY_L, L_COUNTRY - country on left side of the road
• PARITY_R, R_PARITY - numeric parity value on right side of road. A value of 1 means odd parity (addresses are all odd), a value of 2 means even parity (address are all even), and a value of 3 means there is not parity (addresses can be even and odd). For any other value the parity will be automatically determined.
• PARITY_L, L_PARITY - numeric parity value on left side of road. A value of 1 means odd parity (addresses are all odd), a value of 2 means even parity (address are all even), and a value of 3 means there is not parity (addresses can be even and odd). For any other value the parity will be automatically determined.

Only the start and end address number are absolutely required for the side of a road to have addressing, in addition to the road having a name.

If one or more point features are selected, the Add Coordinate Attributes to Selected Point(s) option will appear when right-clicking. Selecting this option will cause X and Y attributes to be added (or updated if they already exist) to the selected points with the value being the coordinates of the points in the current projection system.

There are multiple ways to assign attributes to features from other features. This includes, applying attributes to areas from points in those areas, applying attributes to points from the area they are in, and applying attributes to lines from area features they are in. Each of these options is further described below.

If one or more area features are selected, the Add Attributes to Selected Areas from Points option will appear when right-clicking. Selecting this option will cause Global Mapper to search for any point features within each area and, if found, add the attributes from the included point feature to the area's attribute list. If multiple points are found within the area the user is prompted whether or not to use the attribute data.

If one or more point features are selected, the Add Attributes to Selected Points from Areas option will appear when right-clicking. Selecting this option will cause Global Mapper to search for the top-most area feature with attributes that each point feature is in and, if found, add the attributes from that area to the point's attribute list.

If one or more point features are selected, the Add Attributes to Selected Points from Lines option will appear when right-clicking. Selecting this option will cause Global Mapper to search for the nearest line feature (within the specified search distance) with attributes and, if found, add the attributes from that line to the point's attribute list.

If one or more line features are selected, the Add Attributes to Selected Lines from Areas option will appear when right-clicking. Selecting this option will cause Global Mapper to search for the top-most area feature with attributes that each line feature is in and, if found, add the attributes from that area to the line's attribute list.

If one or more area features are selected, the Add Attributes with Count of Points and Lines in Selected Area(s)... option will appear in the right-click menu. Selecting this option will count the number of point and line features completely contained within each selected area and add the counts for each area to the attribute list for the area as LINE_COUNT and POINT_COUNT attributes. This can be handy for doing something like counting all of the points within the loaded areas, then setting up the drawing style for the areas based on the new POINT_COUNT attribute on the Area Styles tab of the Options dialog for the layer that the areas are in, so you can color based on how many points were in each area.

If one or more area features with separate islands/holes within them are selected, the Create Single Vertex List Area From Selected Area(s) With Islands option will appear in the Advanced Feature Creation sub-menu of the right-click menu. When selected, this option will connect all of the islands/holes within the selected parent areas into a single vertex list and replace the original parent/island area with a new area that contains just that single vertex list. This is useful for converting areas with islands into a form that software that cannot handle areas with holes can make use of.

If one or more points and one or more lines are selected, the Connect Selected Points to Selected Lines with New Lines option will appear in the Advanced Feature Creation sub-menu of the right-click menu. When selected, this option will create a line segment from each point to the closest point on any of the selected lines features.
