PROFILE TOOL (gis.m)

6       The  Profile  Tool  will draw a 2-dimensional profile of the surface of
7       any raster map. The profile will be calculated along a  transect  line,
8       drawn with  a mouse on a map display. The transect line can be a simple
9       line (i.e., with only a beginning and ending node) or a  complex  poly‐
10       line (i.e., with multiple segments, delineated by multiple nodes).
11
12   Using the Profile Tool
13       The Profile Tool is started by clicking on the profile button () on the
14       toolbar of a map display window.
15
16       1      Click the map button on the Profile Tool  toolbar  to  select  a
17              raster  map to profile. The map to profile can be different from
18              the one displayed.
19
20       2      Click the transect button to begin drawing a transect to profile
21              with a mouse the current map display (i.e., the map display from
22              which you launched the Profile Tool). Draw by holding  down  the
23              left button to make a "rubber-band" line for each segment of the
24              transect. A transect can have a single, straight segment or mul‐
25              tiple  segment.  There is no need to "end" the drawing. The Pro‐
26              file Tool will profile the drawn transect at any time.  You  can
27              also   extend an existing transect and draw a profile of the new
28              transect.
29
30       3      Click the profile button to create the profile.
31
32       The profile extends from left to right in the profile display. The hor‐
33       izontal (x-axis) scale represents the total distance along the transect
34       to be profiled. Vertical lines mark each node on a multi-segment  tran‐
35       sect  and  show  the total distance along the transect to the node. The
36       vertical (y-axis) scale is in units of the map that is being  profiled.
37       All  scaling  and  axis labels are created automatically, and cannot be
38       changed by the user.
39       • The erase button will erase the current transect and profile.
40       • The save button will save the profile to an  Encapsulated  Post‐
41       Script (.eps) file.
