       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.
