I'm new to mapping and GIS and I'd like to setup a mapping system to display information on a map, I think the following could work but I'm not sure how good it is..
I store my data (lat, lng etc) on a PostgreSQL server
I build a GeoJson file containing the information I want to display on the map (using the data on the postgresql server)
I send the Geojson file to TileMill / PolyMaps / etc
Do I need to use tileStream or something to serve the tile ? To build on almost real-time system all I need is to rebuild the geoJson file right ? is Wax useful for me ?
