Using the da.Updatecursor, I tried modifying the z values of individual vertices, creating a new geometry object, and replacing the existing geometry with the z-modified geometry. cursor = arcpy.da.UpdateCursor(out_features, ["SHAPE@", height_field]) for row in cursor: newGeom = arcpy.Array() for part in row[0].getPart(): newPart = ...

GDAL can read/write these raster formats with the SRTMHGT driver. This means you can view the raster with QGIS, ArcGIS, or use GDAL utilities like gdallocationinfo to get values from a point, e.g.: Convert DMS to DD: Lat: 50°24'58.888"N = 50 + (24 / 60) + (58.888 / 3600) = 50.4163577778 Long: 14°55'11.377"E = 14 + (55 / 60) + (11.377 / 3600) = ...

DEMs and Hillshades are two different things. DEMs are surfaces with elevation information. Hillshades are a visual representation of a shaded relief and the values are not dependent on the elevation itself but of the aspect and angle illumination, as you noticed from 0 to 254. If you'd like to represent a map with elevation data but using the visualization ...

The units of the graph and how to change them depend on which axis you're looking at. First, the horizontal units are the same as your current map projection. If you are using a Geographic coordinate system, the units will be degrees. If you're using a standard UTM projection, the units will be meters. The only way to change this use a different projection, ...
