Hi,
I am trying to create an Elevation Profile service using the Python code found on the link:
http://www.arcgis.com/home/item.html?id=0d47b17d3b884b9d977a6f76fc6bfcaa
And I followed all the instructions. I am able to publish the geoprocessing service, but when I run the gp service inside ArcGIS I get an error saying:
Error executing tool.: Failed to execute. Parameters are not valid. ERROR 000840: The value is not a TIN Layer. ERROR 000840: The value is not a Raster Layer. ERROR 000840: The value is not a Terrain Layer. ERROR 000840: The value is not a LAS Dataset Layer. Failed to execute (InterpolateShape). Failed to execute. Parameters are not valid. ERROR 000840: The value is not a TIN Layer. ERROR 000840: The value is not a Raster Layer. ERROR 000840: The value is not a Terrain Layer. ERROR 000840: The value is not a LAS Dataset Layer. Failed to execute (InterpolateShape). Failed to execute (Profile). Failed to execute (Profile).
The problem seems to be in the Interpolate Shape analysis in line 307 but I am not sure what is wrong with it. Do you guys have any ideas? Here is the code below. Thank you so much!
