interactive polygons on map

[Michal_M]

Hi,

I need to create vizual with map. On map I need to have certain polygons. Those polygons should be interactive - should act as a filter to show other vizuals on dashboard. Where to start? What kind of vizual I need (Shape map, azure map, other)? What kind of source data I need, in which format? I have txt file with geo coordinates of one polygon.

Hi @Michal_M

Yes, the correct approach for your requirement is to use the Azure Maps visual with GeoJSON polygons.

It supports:

• Clickable polygon regions
• Cross-filtering other visuals in the report
• A more future-proof solution compared to older map visuals

How to start:

1. Convert your TXT polygon coordinates into GeoJSON format
2. Add the Azure Maps visual in Power BI
3. Load the GeoJSON as a polygon layer
4. Enable selection to allow filtering of other visuals

Important: Power BI does not read TXT polygon files directly—you must convert them into GeoJSON first.

Please mark this as solved if it resolves your issue.

Hi @Future_To_BI 

I prepared my GeoJason file. But I do not know how to load it as a polygon layer to my visualization. I do not have such an option. I created table with GoeJSON coordinates in one column, but When I add it to Azure map as a Location, nothing is happening

Hi   -Power BI does NOT natively perform point-in-polygon calculations,  you can use Azure Maps visual in Power BI (supports custom polygon(GeoJSon).

use this link: geojson.io | powered by Mapbox to convert your text with accurate coordniates.

Hope this helps.
