I would like to create centerlines for many glaciers I am doing work with in ArcMap. I feel like I have a conceptual model that could work but can't seem to figure out how to make it happen with the tools available. I have polygons for each glacier outline, and DEMs for elevation data.
My idea is as follows:
- Using zonal stats find max/min elevation for each glacier using the outline polygons
- Turn the max and min pixel into a point file
- Then find either a least cost path using the DEM between the max/min for each glacier(seems complicated) or find the path between the two points that lies in the center of either side of the polygon.
It's the last step I need help with.
