Spatial SQL -> OpenStreetMap is mapping the world

OpenStreetMap is a wiki-like map that anyone in the world can edit. At it's start OSM data was partial and inconsistent. But now (mid 2014) we are seeing impressive coverage that can be used in GIS projects, WEB maps and other Location Based solutions. OSM data is available for free download from official OpenStreetMap www.openstreetmap.org site or from this site: download.geofabrik.de in XML like format (.osm) or in ESRI Shape file format (.shp). The huge advantage of OSM is it's open licence status and use of crowd-sourcing for data collection. You can register and start to edit spatial layers on OSM web site almost immediately: add roads, house numbers, upload GPS tracks files, draw buildings, points of interest and so on. You can contribute your data and fix/enrich edits of other users.
