Så kom Google svar på Maker fra GeoCommon (fortius) ...
Google's GeoCommon look alike ...
Posted by Lalitesh Katragadda, Creator Map Maker and Lior Ron, Product Manager
Here is how you can use these new features.
JS API syntax
Use G_MAPMAKER_NORMAL_MAP and G_MAPMAKER_HYBRID_MAP in lieu of the normal map and hybrid types to show mapmaker map tiles and hybrid tiles respectively. Remember that these serve maps only for the countries being edited in mapmaker, not all the countries available in maps.google.com. If you're making a mashup with a global audience, you may want to add logic to switch between the map types, or offer the option to the users.
Static Maps API syntax
users can access mapmaker tiles using 'maptype' values of "mapmaker-roadmap" or "mapmaker-hybrid" e.g. http://maps.google.com/staticmap?center=31.494445,74.334011&zoom=15&size=512x512&maptype=mapmaker-roadmap&key=MAPS_API_KEY&sensor=false
See the comparison of this URL vs the same URL without the "maptype=mapmaker-roadmap" for Lahore, Pakistan.
If you have data that you want to update yourself - whether you're a city GIS expert, a company's webmaster or just a local expert, you can edit map maker and the new data will show on your mashup within a day.
