ArcPy to extract elevation from Raster DEM.

Question

Hi,

I have a Raster DEM and I would like to extract elevations from it based on the lat longs and update those elevation values in the database. I have searched for classes and functions in ArcPy to deal with this task. I found RasterToNumPy() function but I am not able to understand what this function does and how could I use it to make my job done. Any help in founding the right function in ArcPy to deal with Raster data or a sample script would be greatly appreciated.

Regards,

Abdul

Ahhh, I think you have it Curtis, it is a picture/image of a dem and not a raster that IS a dem

Also curious...

"have a multi band Raster DEM"

A DEM raster is normally single band, you only have one elevation surely?

Recent example of RasterToNumPyArray and back https://community.esri.com/thread/190930-error-010240-could-not-save-raster-dataset#comment-669963

but this is a python question for sure
