Objective: calculate area of valley fill upstream of each catchment site.
Workspace: ns-ecotools.win.duke.eduf$MTR2012
Steps
- Download valley fill shapefile from http://gis.dep.wv.gov/data/vector/vallf.zip
- Convert to raster for MTR study area
- Feature to raster (cellsize, extent, snap raster, mask == DEM, value = FID)
- Convert to binary raster
- Con(IsNull(Raster(r”F:MTR_2012MTR_10May2012Scratchvfill_nd”)),0,1)
- Calculate flow accumulation weighted by binary valley fill raster
- Using the FlowDirection raster in the SkyTruth SDE database
- Extract accumulated flow values at snapped watershed points
- Accumulated flow result saved to SkyTruth SDE as AccumValleyFill
- Adjusted “Extract Data for Points” model to include accumulated valley fill in outputs
