Arc Extract Breakline from DEM: Difference between revisions

<br>

This method requires that the line has been digitised at the high or low point that you are trying to represent. If the vertex on the line, is not at the crest of the ridge, the elevation may be slightly out.<br>

Method 2 creates a buffer around each points and can be used to extract the maximum, minimum or average elevation from the DEM within this buffer. This ensures that the control is represented, even if the line does not follow the levee crest or centreline perfectly. The steps involved are:
