resizable buffer zone widget for point features?

KevinBraden — Mon, 12 Dec 2011 17:26:26 GMT

Hi all,

I am wondering if anyone knows if there is a widget (or similar geoprocessing tool) available to aid in the following scenario:

A user zooms to a point on the map and sees point features of various layers. the user wants to see how many of these points exist within an area using a radius defined by the user, say 1-100 miles. the resulting action would be a semi-transparent area wherein the user sould see the points that fall within the queried radius.

Any thoughts?

Thanks,

-Kevin

This sample is close to that:

After getting the buffer, you could query the layer instead of calling a GP.

Dasa,

Thank you for the link and the information. It looks like it will set me on the right path for a custom solution.
