Live Search (aka Live Maps, aka Live Local) have enabled publication of Collections of map data as GeoRSS, Google Maps as KML, or shared via a permalink. OpenLayers can serialise and deserialise gml, kml and georss, WKT and more…
Interesting times, we should be seeing more sharing and publication of these datasets, showing much more than a simple list of points can do. They approach GIS.
But, are they (excl. openlayers) free, is it derived data?
You use their mapping product, and make a derived work from it.
Who owns the copyright?
What are the terms?
Maybe the old “is drawing on a map derived data” question is about to be answered? Perhaps it can open the floodgates to better datasharing, more free geodata and better mashups and spatial applications….
