Hi all,
I have a query about using the elevation profile tool in ArcGIS Earth v1.8/v1.9. When i create a profile between the same two points, it appears the average percent slope differs from going low to high and high to low (see below).
Results are:
Low to High – average slope: 49.98% -17.15%
High to Low – average slope: 12.87% -56.9%
We are using our own elevation service to calculate the elevation profile. I'm sure there is a simple answer for this but i cannot think of one off hand. Any assistance would be most welcome.
Thanks,
Andrew
Hi Andrew,
Thanks a lot for your feedback.
It seems that there was a bug here. The absolute values of average slope should be the same from going low to high and high to low.
The slope = 0 range was also included in the method when calculating the uphill, but it should be ignored. We will fix this issue in the coming 1.10 release.
Thanks,
Xuewen
