I have an OpenStreetMap PostGIS database and would like to select specific data (for example all shops) of each tile (on a defined zoomlevel) on the planet. Is this possible to achieve and if yes, how?
Retrieve data in POSTGIS:
You need to import OSM vector data and then using postgis and qgis (Qauntum GIS) you can visualise your query results
PostGIS retrieval of amenity
