- <h2>PROFILE TOOL (gis.m)</h2>
- 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).
- <br>
- <h3>Using the Profile Tool</h3>
- The Profile Tool is started by clicking on the profile button
- (<img src="icons/gui-profile.gif" alt="Profile icon">) on the toolbar of
- a map display window.

- </div>
- <ol>
- <li>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.
- </li>
- <li>
- 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.
- </li>
- <li>Click the profile button to create the profile.
- </li>
- </ol>
- <div align="center">
- <img src="gm_profile3.png" alt="Profile plot" height="264" width="400">
- </div>
- <br><br>
- 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.
- <br><br>
- • The erase button will erase the current transect and profile.
- <br><br>
- • The save button will save the profile to an Encapsulated PostScript
- (.eps) file.
