Spatial analyst viewshed tool bug in pro

DanielBarbato — Thu, 26 Oct 2017 02:56:22 GMT

why is the viewshed tool missing some parameters in arcgis pro? it doesnt have the input box for refractivity coefficient or checkbox for 'use curvatuure corrections'. I thought they may have been removed, but they are still shown on the help page. This is the spatial analyst tool, not the new ready-to-use tool.

From the help Viewshed ... they are clearly noted in the help, but yes, they are missing from the tool itself

But it is in Viewshed 2

I notified them about the difference via the 'what do you think' link at the bottom of the help page

Hi,

It is not a bug. Pro tool hides parameters that are disabled. The parameters will show up when they become enabled.

Checkbox for 'use curvatuure corrections' parameter:

This parameter is disabled by default so it is not showing up. To enable it, please pick the input raster on the tool dialog. After that, 'use curvature correction' parameter will be enabled and it should show up on the tool dialog.

Refractivity coefficient

This parameter will only show up when 'use curvature correction' is checked on. Follow the steps above to enable the 'use curvature correction' parameter, then check it on. Then the refractivity coefficient parameter will show up.

Thanks,
Xuguang Wang
