Query about ArcGIS Earth Elevation Profile Average Slope

AndrewJohnston — Wed, 07 Aug 2019 23:04:38 GMT

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
