Intersect/select point feature (from a service) with a drawn polygon feature in AGOL Web App.

Hey!

I wondering if somebody knows if it is possible to make a Web app that can do as follow:

1: We got a basemap with point features on.

2: I want to select some spesific point features by drawing a polygon over them.

3: I want to extract the attributes from the points selected and i whant to count number of points selected.

4: The polygon that I darw should be visible after drawing.

Hope somebody as a thought on this.

If the polygon should not stay visible, the Select widget—Web AppBuilder for ArcGIS | ArcGIS in the Web AppBuilder would probably be the easiest way to go (see What is Web AppBuilder for ArcGIS?—Web AppBuilder for ArcGIS | ArcGIS ).

You select the features drawing a polygon (or rectangle), it will provide a count of the features within and it allows you to view the attributes of the selected points.

However, the polygon will be removed after selection of the points.

I have tried that, and yes that works, but the real challenge is with the polygon. I want to export the drawn polygon to another web map. I have tried to find a solution in GeoEvent extension. But have not succeeded yet.

Thank you for the answer.

GeoEvent would not be the functionality to solve this. You can however create a script that does this for you and inserts the geometry into a service and publish that as a geoprocessing service and consume it with the Geoprocessing widget. How long should this polygon persist and should this only be available for the user that drew the polygon?

Yes, maybe thats the best solution. The polygon shall stay in the webmap for approximately 3-4 days and than automatically deleted. This service is intended to be running for some years. (I hope). I haveneverd tried to make a script before, but will try

Thank you for the help
