I'm trying to identify the Location (lat/lon) and upstream area of every raster point that flows into the Arctic Ocean (there are a lot so it has to be fully automated). I'm starting with the following rasters:
- Flow Direction
- Accumlated Flow Area
My approach so far has been to use the above rasters to create a delineated basin shapefile. From there I was hoping I could use the shapefile to look at the Flow Accumulation Raster and identify the location of the maximum value in each basin. In terms of output, I just need a table that shows [Basin#, Longitude, Latitude, UpstreamArea] for every basin.
Any ideas or tips would be apreciated. [Note that I've already looked here but I don't know how to restrict the raster to only the area bounded by the polygons in the shapefile]
*Using: ArcGIS10, Python, etc.
