I work for TNC and we would like to calculate average and max cross slope of the public trails at our preserves. is there a way in ArcGIS pro to calculate average and max cross slope?
I used polyline trail data and a DEM to calculate the elevation profile for our individual trails, which calculates the average and max running slope. I am assuming I would need a gpsed polygons for our trails taken in the field to calculate cross slope, but am unsure what tools (if any) are available for this calculation.
Thanks for any advice!
Hi Stephanie. To get average cross slope I would create transect lines perpendicular to your trails at an appropriate interval and length, and use these to get 'cross' elevation profiles as you've done already. There is a new transect tool in the sampling toolbox: https://pro.arcgis.com/en/pro-app/latest/tool-reference/data-management/generate-transects-along-lin...
