The Export Simple ASCII Text File command allows the user to export any loaded vector data sets (i.e. areas, lines, and points) to a delimited ASCII text file. Each vertex in an area or line and the position of each point will be represented.

To export a simple ASCII text file go to Export > Vector / Lidar formats and select Simple ASCII (XYZ) Text File as the export format.

When selected, the command displays the ASCII Export Options dialog which allows the user to setup the export. The dialog consists of an Options panel (pictured below) and an Export Bounds panel which allows the user to set up the portion of the loaded data they wish to export.

The Options tab (below) allows the user to specify what character to use to separate the x, y, and z coordinates of each vertex. In addition, the user can specify that they wish to separate each vector feature with a blank line or some other custom separator text.


The Coordinate Order section allows the user to control the order in which the X (easting/longitude) and Y (northing/latitude) coordinates are exported.

The Coordinate Precision section allows you to control how many digits of precision to include with each coordinate value. The export of elevation data is controlled with the Export Elevations option.

The Include Feature Attributes Before Coordinate Data and Include Drawing Style Attributes Before Coordinate Data options, respectively, control whether or not feature attributes or feature drawing style information is saved to the file on the lines preceding the coordinate data for a feature.

If elevations are being exported, Global Mapper first looks for an elevation associated with the vertex being exported. If no elevation is associated with the vertex, Global Mapper then checks all loaded elevation grid data in reverse order of display to see if any of them have an elevation at the vertex location. If so, that elevation is used.

The Coordinate Offset/Scale tab (below) contains options to set Scale Factors and Offsets for X/Y/Z coordinate values.
