Map card in azure map

Hi RubenMerino ,
Thanks for reaching out to Microsoft Fabric Community,

Hope your query has been resolved by now - if not, please consider the following insights:

Based on your setup and screenshots, the main issue arises from how Azure Maps handles GeoJSON reference layers. While these layers successfully display the territorial boundaries, hover tooltips do not automatically appear because reference layers do not natively support interactivity like tooltips unless there’s a precise data join.

In the second case (dot map with lat/long), the map visual directly consumes the dataset and plots each point interactively, allowing tooltips (like "nom") to be displayed on hover.

When using a GeoJSON reference layer:

The shapes are rendered correctly, but :

Unless the "nom" column is matched exactly and used as a Location field (with  context like region/country), the map cannot resolve it interactively.

Additionally, Azure Maps does not expose attribute-level tooltips from reference layers by default.

Workarounds:
Use Latitude/Longitude with a Bubble Layer:

-Plot your dataset using Latitude and Longitude.

-Add "nom" to the Tooltip field.

-This allows hover text as expected, and you can still overlay the GeoJSON as a visual aid.

Ensure Matching Location Fields:

-If you wish to use "nom" for matching, try appending contextual identifiers (like postal code, province, or "Catalunya, Spain") so Azure Maps can resolve the location.

-Alternatively, use a common ID column between your dataset and the GeoJSON to link them meaningfully.

Let us know if you're still working on this - happy to help further.
