how can I make a map with editable data+discussion

I want to make a map with apx 100 towns marked on the map, and I want to edit structured data about each town, and a bonus would be for the map to apply conditional formatting based on the data. For example, the towns that have high speed internet, color them green. The towns that can hear FM radio broadcasts, color them yellow, and the towns with no telecommunications, color them red. And when a town gets a new internet installation, I can edit the data via Decko, and the color of that town (a polygon, not a point) changes to green.
