I need to find the slope areas A) between 28º and 55º, B) contain an abrupt change of more than 10º, C) are more that 625 m2 in area, and D) are adjacent to glaciers
VERSION: ArcGIS Pro 2.9.2
INITIAL LAYERS: DEM_Slope, Glaciers_Raster
This is the workflow I have put together:
Slope Interval (28º to 55º):
Slope Change (>10º):
Large Surface Areas (>625 m2)
Close to Glaciers:
RASTER TO POLYGON: "Reclassify2_EuclidDistGlaciers" -> RastToPoly_ReclassEuclidDistGlaciers
Is this workflow OK? What mistakes am I making? Should I try a RWO approach instead? THANKS!
Solved! Go to Solution.
see you other thread Calculating slope change - Esri Community
Results? Do they make sense? or did you get any errors?
During the process were the cell sizes the same? snap raster? extent?
Environment parameters will have an effect on processes and output
I'm thinking about trying a different approach. See the following post in ArcGIS Pro Questions:
profile or plan curvature?
Curvature (Spatial Analyst)—ArcGIS Pro | Documentation
Huh! I think that's exactly what I need. You're a genius!
If I understand correctly, the input raster would be my DEM_Slope raster. Or am I confused here?
And what constitutes noisy data and how do I know if I have it? High resolution?
My cell size is 10mX10m. Is that high resolution? And if so, should I try the SURFACE PARAMETERS tool instead?
