We (I'm from there) used to have a map like yours, but that was years ago. But the database should be easy to ask for access or a copy, even if slightly dated.
Brazil has many "valleys" such as SPV you can use to enrich your data.
Some Feedback :
- A few times, while using the automatic translation of Firefox (I don't speak portuguese) I ran into critical bug while hovering the map, that "deletes" the whole page and leaves me with an error message : "Erreur d'application: une application client a une exception lors du chargement de saas-map.ssr.trapiche.cloud (voir la console du navigateur pour plus d'informations)." in the console I get : "Uncaught DOMException: Node.removeChild: The node to be removed is not a child of this node > NextJS"
- I use Firefox with zoom on by default, and its not dealt with properly : the floating window on the map is right above what I am pointing at and hiding it. Really annoying.
- Clicking on "commençar gratis" I get to "Error Loading Deployments - HTTP 401: Unauthorized"
Good luck with this project. I like the idea of a micro-SaaS map, but it needs some more work, at this stage.
