Highlighting your map’s area of interest is often job one for a map. If not job one, then at least job three or four. And that’s still a pretty high priority. Here’s how you can trick an unsuspecting group of layers into becoming a clipping mask in the ArcGIS Online Map Viewer…
No time for videos? I get it. Here’s the rundown…
- Pick a basemap (this will be what appears as your not-area-of-interest)
- Add your interest layer
- Add a layer whose shape you want to use as a clipping mask (cookie cutter)
- Group the interest layer and the clipping layer, with the clipping layer on top
- Give the clipping layer a Destination Atop blend mode
- Profit
Check out this blog post from Bern Szukalski that goes into a lot more detail and provides more examples and use cases.
Are you more programmatically inclined? The geniuses on the ArcGIS for JavaScript show you how to do it that way in this code sample. Whichever way you prefer, you will be masking and clipping and area-of-interesting your way right to the top.
Happy Masking! John
Thank you for showing this example of how to move from the screening widget to the near me widget as our agency has asked us to begin moving our projects from WAB to ExB. I’m wondering if further refinement of the Near Me widget will streamline this process. While the results can still be obtained, users must now use 3 apps to get to the desired report, and the report is spread out onto separate pages for each layer. My end users are community groups that generate a report for a grant application. Most have little technical capabilities and may… Read more »
