Elevation Analysis


After creating a surface, it is possible to use Maptitude for elevation analysis, i.e. to measure individual spot heights, and to determine elevation profiles.

To do this, select your grid (surface) layer on the current map, and choose Toolbox on the Tools->Surface Analysis sub-menu. You may be prompted with some surface analysis options. Make sure these are set correctly. Typically, you will have to set the layer, data (elevation) field name, and the elevation units. The Surface Analysis Toolbox will then be displayed:

To measure a spot height, press the Spot Height button (far left with green profile and ruler). Move the mouse to the map where it turns into a cross-hair. Click at the required location on the grid surface layer, and that location’s height will be displayed as the Estimated Value on the Surface Analysis Toolbox.

Maptitude can also measure an elevation profile. To do this, press the Show Profile button (second from left with green profile and red line). Next, draw the profile on the grid surface layer. Click once for the start location, and click a second time for the end location. Here is an example using the Guadalupe Mountains example:

Here is the resulting elevation profile:

The Surface Analysis Toolbox can also be used to determine visibility.
