Please help on how to perform Change detection operation on image in ArcGIS Runtime for .NET.
not found change detection tool in ArcGIS Runtime Local server geoprocessing tools list.
can please confirm is it possible using Geoprocessing Service.
The Change Detection geoprocessing tool isn't currently supported for use with ArcGIS Runtime Local Server and there are no plans to add support for this tool (it requires the Image Analyst extension which is not available with Local Server). But many Spatial Analyst and 3D Analyst tools are supported, which may meet your requirements depending on the workflow you are trying to implement.
Thanks for your response. any work around for this ( Change detection tool Publishing as geoprocessing service using ArcGIS Pro and access services instead of gpk ). will it works?
Yes, if you publish a geoprocessing model/script as a geoprocessing service with ArcGIS Enterprise (see What is ArcGIS Image Server?) then you could access that service via the geoprocessing task in the ArcGIS Runtime API to perform analysis on the server. The output of the change detection tool is a raster dataset, you might choose to use the API to download this from the server output location to the client machine, or alternatively publish the geoprocessing service with an associated map service and access the results by referencing the map image layer on the server.
See this sample for an example of accessing a result map service: Local server geoprocessing (ignore the fact that it's using a local server, the concepts are the same).
