I'm using ISurface.GetElevation on a Raster to get the elevation for a specific lat/lon.
I have to do this for a huge set of datapoints.
Currently i'm testing with a dataset of 10.000 items which takes Esri over 30 seconds but is executed by GlobalMapper within half a second.
Is there any other way to quickly retrieve the elevation (bi. interpolated if needed) using Esri ArcObjects function ?
I'm working in C#
Thank you for your help!
