Global Mapper Edit Feature Type

[Mauricette Atencio]

I have done Vertex editing/ Edit Features Vertices/ Add Elevation the problem with that is that I have to select the first and shift last point then press add elev. Is there a short cut key that select all vertices at once

Is there a way to copy an attribute to an elevation, I was not able to export an x,y,z text file with the attribute , I can only export text file with x,y,z and elevation. So I need to create an elevation attribute when I create a feature? Is there a line feature type that has Elevation built in?

The Digitizer Tool allows you to modify existing vector features as well asto create new ones. This tool encompasses a lot of functionality, from modifying theshape and position of area, line, and point features, to editing the attribution anddrawing styles of individual vector features. The major activities available with the Digitizer Tool are described below.

At any time that the Digitizer Tool is active, you have the option tocreate new area, line, and point features simple by right clicking and selectingeither the Create New Area Feature,Create New Line Feature (Vertex or Trace Mode), orCreate New Point Feature options on thepopup menu (pictured below). Any new features created can be exported to new vector files in any of the supported vector export format (DXF, Shapefile, etc.).

After selecting the Create New Area Feature popup menu option, you can proceedto draw a new area feature with the mouse. To draw the feature, simple left click ateach place that you'd like to drop a vertex. To finish the area feature, right clickat the desired location of the last vertex to complete the area. You can cancel creationof the new area at any time by pressing the Escape key. Note that while drawing thearea you can use the Snapping feature to help align thearea with existing features.

Once you've completed drawing the area, the Modify Feature Info dialog willappear allowing you to setup the label, classification, drawing style, and attributionfor the area. The perimeter and enclosed area of the area feature will be addedas default attributes. The units for these measurements can be modified on theGeneral tab of the Configuration dialog. See Editing Feature Attributes and Drawing Styles for more details.

Once you have completed have completed creating the area, the Digitizer Tool willremain in the area creation mode, so you can simply start left-clicking to drawanother area, or right-click to choose a different mode.

You can also create new area features from selected line features by selecting a collection of lines, then right-clicking and selecting theAdvanced Feature Creation Options->Create New Area Feature(s) from Selected Line Feature(s) menu command. This will attempt to connect the selected line features to build area features.All line features will be connected as far as possible, then closed to createa new area feature.

After selecting the Create New Line Feature (Vertex Mode) popup menu option, you can proceedto draw a new line feature with the mouse. To draw the feature, simple left click ateach place that you'd like to drop a vertex. To finish the line feature, right clickat the desired location of the last vertex. You can cancel creationof the new line at any time by pressing the Escape key. Note that while drawing theline in Vertex Mode you can use the Snapping feature to help align theline with existing features.

You can also choose to draw a line using the Create New Line/Area Feature (Trace Mode) popup menu option. To draw the feature, simple press the left button to start the line/area, then tracethe path to draw using your mouse while keeping the left button pressed. To finish the feature, simply release the left button. You can cancel creation of the new feature at any time by pressing the Escape key or just releasing the left button then pressing Cancel on the dialog thatappears. If you are using a digitizing table just select this mode, then press down the pen tostart, trace the path, then release it to end. If your drawn path is nearly closed, you willbe asked whether to create a closed area feature from the path or just keep it as a line feature.

Once you've completed drawing the line, the Modify Feature Info dialog willappear allowing you to setup the label, classification, drawing style, and attributionfor the line. The length of the line feature will be added as a default attribute. The units for the length measurement can be modified on theGeneral tab of the Configuration dialog. See Editing Feature Attributes and Drawing Styles for more details.

Once you have completed have completed creating the line, the Digitizer Tool willremain in the line creation mode, so you can simply start left-clicking to drawanother line, or right-click to choose a different mode.

You can also create new line features from selected area features by selecting one or more areas, then right-clicking and selecting theAdvanced Feature Creation Options->Create New Line Feature(s) from Selected Area Feature(s) menu command.This will create a single closed line feature from each selected area feature.

After selecting the Create New Line with Dist/Bearing/COGO popup menu option, you can proceedto select the starting location of the new line feature by left clicking at the desired startlocation. Note that while selecting the start point for theline you can use the Snapping feature to help align theline with existing features.

After selecting the starting location, the Distance/Bearing/COGO Inputdialog (pictured below) will display, allowing you to enter distance/bearing information for additional points either as separate distance/bearing values, as a COGO (Coordinate Geometry)coordinates (see below for explanation), or as a quadrant/bearing/distance value. Once you have entered all of your points, press Done to complete the process and create the new line feature.

You can also check the option to Close Path Using Compass Rule when Completing Feature. If thisoption is checked, all of the points will be adjusted using the compass rule to ensure that the shape isclosed. The compass rule evenly distributes the shift required to close the shape to all vertices andis commonly used by surveyors.

You can achieve very fast entry of large collections of distance/bearing of quadrant/distance/bearingvalues by simply using the number pad and pressing Enter after each value. This will take you to thenext field and finally add the point when you press Enter on the last field. This will also take youback to the first field to allow continuously adding points with only one hand, keeping your other hand free to mark your place on the list of values.

When entering data using the Specify Separate Distance and Bearing Values option,the bearing values are degrees clockwise from true north, so 0 degrees is north, 90 degreesis east, etc. For the Specify Using Quadrant/Bearing/Distance option, you specify a quadrantvalue of 1 to 4, with 1 being the NE quadrant, 2 being the SE quadrant, 3 being the SW quadrant,and 4 being the NW quadrant. The bearing values are then east of the NS line for quadrants 1 and 2and west of the NS line for quadrants 3 and 4.

It is also important to remember that any bearing are specified relative to true north (unless you check the Use Grid Bearings Rather Than BearingRelative to True North), so if your projection isn't oriented so that straight up is true north (most projected systems, like UTM, are not unless you are right at the projection center) a line of bearing 0 won't be straight up, but will be slightly skewed so that it points at the North Pole. A line of bearing 0 will be straight up in projections like Geographic or Mercator where true north is always straight up.

The first character of a COGO input string must be either the character 'N' or 'S' to indicate whether the bearing is relative to the north or south directions. After another space, the angle begins. The angle can be in any angle specification that Global Mapper supports, including degrees,degrees/minutes, or degrees/minutes/seconds. A space follows the angle, and is then followed by either the 'E' or 'W' characters. A space separates the bearing from the distance (which should be in appropriate linear units).

For those unfamiliar with the notation for bearings: Picture yourself in the center of a circle. The first hemispere notation tells you whether you should face north or south. Then you read the angle and either turn that many degrees to the east or west, depending on the second hemisphere notation. Finally, you move distance units in that direction to get to the next station.

After selecting the Create New Point Feature popup menu option, you can proceedplace 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 optionto create a new point feature at a manually specified location. When you select thisoption, a dialog appears allowing you to enter the location for the new point featurein either latitude/longitude coordinates or coordinates in the current view projection.

Once you've placed the point, the Modify Feature Info dialog willappear allowing you to setup the label, classification, drawing style, and attributionfor the new point feature. See Editing Feature Attributes and Drawing Styles for more details.

Once you have completed have completed creating the point feature, the Digitizer Tool will remain in the point creation mode, so you can simply left-click to placeanother point, or right-click to choose a different mode.

You can also create new point features from the centroids of selected area featuresor from the vertices of selected line and area features by selecting one or more areas or lines, then right-clicking and selecting theappropriate option under the Advanced Feature Creation Options menu.
