Reconciliation between CC and ODCReconciliation between CC and ODCPosted Jan 24, 2011 11:28 UTC (Mon) by epa (subscriber, #39769)In reply to: Reconciliation between CC and ODC by dlang Parent article: OpenStreetMap's point of no return
Have a look at the OSM data, perhaps as an XML download. You will see that it has a schematic representation, in this case a series of abstract 'tags' which are used to represent concepts such as a road, a building or access rights. It also uses an abstract geometric space, in this case a two-dimensional plane, where points on the earth's surface are mapped onto the plane using the WGS84 coordinate system.
