The DEFINE_PROJ command consists of a single command line followed by a series of lines describing the
projection in the format of an ESRI PRJ file. The easiest way to determine the text for a projection is to setup
a projection on the Projection tab of the Tools->Configuration and then use the Save to File button to create a
new .prj file. Then just open the .prj file up in Notepad and copy the contents to the lines following the
DEFINE_PROJ command line.
The DEFINE_PROJ command is terminated with a single line containing only the text END_DEFINE_PROJ.
For a sample of the DEFINE_PROJ command in use, load some data and then save a Global Mapper
workspace file from the File->Save Workspace menu command. Open the resulting .gmw file in an editor and
you can see how the DEFINE_PROJ command is used to define a view projection and the set it.
The following parameters are required by the DEFINE_PROJ command.
• PROJ_NAME - specifies the name to associate with the projection
DEFINE_SHAPE
The DEFINE_SHAPE command allows a multi-point shape (like a polygon) to be associated with a name.
The projection name can then be used in later commands for things like cropping and feathering to polygonal
boundaries.
The DEFINE_SHAPE command consists of a single command line followed by a series of lines describing
the series of XY coordinate pairs that define the shape. Each line should have a single coordinate value with
the X and Y coordinates separated by a comma.
The DEFINE_SHAPE command is terminated with a single line containing only the text
END_DEFINE_SHAPE.
The following parameters are required by the DEFINE_SHAPE command.
• SHAPE_NAME - specifies the name to associate with the shape
Here is an example of a DEFINE_SHAPE command used to define a feather polygon with a name of
'FEATHER_POLY'
DEFINE_SHAPE SHAPE_NAME="FEATHER_POLY"
