 * [http://wiki.openstreetmap.org/wiki/WGS84 OpenStreetMap uses the WGS-84
 coordinate system]
 * [http://wiki.openstreetmap.org/wiki/Node Latitude coordinate in degrees
 (North of equator is positive) using the standard WGS84 projection]
 * [http://wiki.openstreetmap.org/wiki/Node Longitude coordinate in degrees
 (East of Greenwich is positive) using the standard WGS84 projection]

 WGS84 has bounds of [http://spatialreference.org/ref/epsg/4326/ -180, -90,
 180, 90]

 More importantly than the wiki, in practice data consumers treat OSM data
 as being in WGS84. These consumers include

 - imposm
 - nominatim
 - osmosis
 - coastcheck
 - OSMCoastline
 - cgimap
 - the rails port
