What can I see from here? That’s just the question that viewsheds answer. Viewsheds are a bit of spatial magic, empathy visualized. Here’s how to make a viewshed layer in the ArcGIS Online analysis tools, and how to style it into a sweet illuminating light source.
Ready to light up your map with the glowing terrain of visibility? Here’s how…

Viewsheds are so cool. You feed it some observer locations and, based on underlying elevation data, it cranks out a polygon showing where you can see. So many uses for this. And it’s so easy and fast. I hope you give it a try and share your results!

P.S. Are you interested in making a fancier one in ArcGIS Pro? Here’s how!
If you have any specific questions, kindly drop them under the comment!
Hi @Adeyinka Adekunle, quite a helpful tutorial. I however would like to know if it is possible to edit, delete, etc.. a geographic feature like a point from a layer not from the sharepoint list map but from the ArcGIS for sharepoint web part?(webmap) on the fly. Thanks
Hi Evelyn, we don’t currently offer that in the web part but in the list map feature. I hope this helps.
Hi Adeyinka – when I click List Map I get an error – “No location data found. Make sure your data has valid location information”. I have 2 columns – one for latitude and one for longitude. I have those 2 columns set in List Map. Any ideas?
@Adeyinka and @Brian Strain – I am having the same issue as Brian. Followed your directions above and getting “No location data found.” error as well. I doubled checked that both X and Y fields were multi-line and that data in fields is properly formatted (data actually coming from Survey123 using Power Automate). Any ideas on how to troubleshoot?
@Amy Forsthoefel
Can you edit the columns where you have the X and Y fields to single line or number and reload your data and let me know if you have any more questions.
We are currently working on supporting the multi line column type. Hope this helps
@brian Strain, I apologize this comment didn’t come through and hence the delayed feedback. Currently the team is working on supporting location data stored in multi line of text column type. That’s mostly the reason for that error message. Can you edit the columns where your longitude and latitude are stored to number or single line of text column type, this should solve this issue. Kindly let me know if you have any more questions. After the next release, you won’t need to edit the column type as it will properly display on the map. Thank you for the feed… Read more »
