NAME

       gm_profile - PROFILE TOOL (gis.m)

       PROFILE TOOL (gis.m)

PROFILE TOOL (gis.m)
       The  Profile Tool will draw a 2-dimensional profile of the surface of any raster map. The profile will be calculated along a transect line,
       drawn with  a mouse on a map display. The transect line can be a simple line (i.e., with only a beginning and ending  node)  or	a  complex
       polyline (i.e., with multiple segments, delineated by multiple nodes).

   Using the Profile Tool
       The Profile Tool is started by clicking on the profile button () on the toolbar of a map display window.

       1      Click the map button on the Profile Tool toolbar to select a raster map to profile. The map to profile can be different from the one
	      displayed.

       2      Click the transect button to begin drawing a transect to profile with a mouse the current map display (i.e., the	map  display  from
	      which  you  launched  the  Profile  Tool). Draw by holding down the left button to make a "rubber-band" line for each segment of the
	      transect. A transect can have a single, straight segment or multiple segment. There is no need to "end"  the  drawing.  The  Profile
	      Tool will profile the drawn transect at any time. You can also  extend an existing transect and draw a profile of the new transect.

       3      Click the profile button to create the profile.

       The  profile extends from left to right in the profile display. The horizontal (x-axis) scale represents the total distance along the tran-
       sect to be profiled. Vertical lines mark each node on a multi-segment transect and show the total distance along the transect to the  node.
       The  vertical (y-axis) scale is in units of the map that is being profiled. All scaling and axis labels are created automatically, and can-
       not be changed by the user.
       • The erase button will erase the current transect and profile.
       • The save button will save the profile to an Encapsulated PostScript (.eps) file.
