ArcGIS API Viewshed with specific coordinates

Question

Hello everyone,

I came across the ArcGIS viewshed sandbox today.

https://developers.arcgis.com/javascript/latest/sample-code/sandbox/index.html?sample=geoprocessing-viewshed

So I wanted to perform a viewshed analysis from specific coordinates (47.42120626,10.98630681), as you can do it with ArcGIS Pro/Online. The problem is, I don't know at which part of the script I can implement my own coordinates or how I need to change the script in order to start the analysis from that point.

It would be much appreciated if anyone could help me out here 🙂

Here's a codepen showing a modified version of that sample that performs the analysis at a specific location:

I hope this helps.

Limits are defined by the service authors.  In the case of the service used in the sample above since it's just used just for demonstration purposes having a limit on the radius is understandable.  To learn more about elevation services that are available on ArcGIS Online in general and viewshed parameters and limitations  check out some of these resources:
