We have recently opened a few shops in Atlanta. How can I add new POIs to the TomTom map database?
You need to report a new POI via the Mapshare Reporter Tool https://www.tomtom.com/mapshare/tools/. Our colleagues from the map team will process your request accordingly. This way you will make your POIs searchable.
On the other hand - using TomTom Maps SDK - you can just add the new layer with your POIs displayed on top of the map using markers https://developer.tomtom.com/maps-sdk-web/functional-examples#draggable-marker.
This way you will just display the data without making POIs searchable.
