How to use Image Server data service (DEM) for 3D Analysis or Spatial Analysis?

[xiannianchen]

Hi, friends,

We found that elevation data served via ArcGIS Image Server can't be used in 3D/Spatial analysis tools, say Extract Values to Points in Spatial Analyst. Those tool require raster datasets.

How to configure elevation data served via ArcGIS Image Server to work with 3D/Spatial analysis tools?

Thanks,

Xiannian

Hi Xiannan,

The 3D or Spatial Analysis tool does not directly recognize the image service URL or service connection path, such as:

1. GIS Servers\arcgis on server\SRTMCalifornia.ImageServer
2. http://server/arcgis/services/SRTMCalifornia/ImageServer

as a valid input.

Therefore, to use ArcGIS Image Service (either published through Image Server extension or ArcGIS Server) in GP tools, you will need to use the Make Image Server Layer tool to create a in-memory layer first and then pass the layer as input to the 3D or Spatial Analysis tool.

Also please be aware the size of the image server layer you can make is under constraint of the maximum request size setting of the image service. So, most of the time, we only request a certain extent of the service by setting the Geoprocessing "processing extent" environment setting when calling the Make Image Server layer tool.

Hope this helps.
