How to perform Viewshed analysis offline

[yossharelharel]

Hi,

I work with Esri Map Wpf control to display maps and I load TPK and LPK files to display different layers.

I want to enable user to click on the map and display a Viewshed analysis for this location with some radius. It was easy to made it while working against Esri service online but my app have to support offline too.

I understand I have to get some DEM files. But I don't know how to use ESRI code (C#)  to use those files and calculate it on run time.

Please help.

Thanks

My suggestion would be to create a GP tool and then consume it in the runtime application.
