       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 transect 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
       cannot 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.
