Using Arcpy, how can I determine min and max elevation from a raster DEM layer within my current extent? I'm currently using Data Driven Pages to centre the layout on each feature extent.
I need to determine this elevation difference value in order to get Python to automatically activate the appropriate contour interval feature class (25m, 100m, etc)
The current logic I'm thinking of is to select all cells within current extent, (what is the most convenient way, or arcpy methods() to do this?) place their values in a list, then:
minElev = 99999 maxElev = -99999 for i in myList: if i < minElev: minElev = i for i in myList: if i > maxElev: maxElev = i
then subtract max and min to get the difference value.
I don't think this is the easiest way, is there someone experienced who knows a faster way?
