Filter by Custom Parameters

MeleKoneya — Fri, 20 Feb 2026 16:25:20 GMT

I have a living atlas layer that I would like to filter by the bounding box for the state of Arizona.

I understand that I can do this with Custom Parameters in the map viewer.

Can someone provide some guidance as to what parameters are needed and the format for them?

Thank you,

Mele

You can define custom parameters for a layer in the settings of the web map:

Documentation for the types of parameters accepted can be found here:

In my screenshot example, I used inSR = 4326, and geometry=-114.8165,31.3322,-109.0452,37.0043

Hi @MeleKoneya , to filter by a specific state name, the custom parameter in Map Viewer could look similar to the following example,

Note: Use the Fields panel in Map Viewer to confirm the Field name that contains State Name information.

Thank you for including this:

inSR = 4326, and geometry=-114.8165,31.3322,-109.0452,37.0043

I was not having much luck find a good example.
