Starting work on the tabulate area tool for webgis. Although the tasks are easy to perform using ArcMap, I'm running around in google circles trying to do it in the web environment. Some questions I have yet to answer:
1. How to define a spatial subset of the map service to query? Vector data supports spatial queries but I'm not finding this with raster data. Possibly setting the spatial extent in the GP environment?
2. The Spatial Analyst Zonal Geometry as Table or Summary Statistics tools are logical candidates for performing the calculation but that means writing a Python GP service
3. Can a Python GP service connect to a map service for processing? I found this blog post that is close to what we want to do but the raster is a local file on the server. http://blog.mapvibes.net/2011/06/real-life-geoprocessing-service-in.html
