Google announced yesterday that KML is now an official OGC standard. With this step, KML has taken yet another step in a remarkable “career”: originally developed by Keyhole (hence the name Keyhole Markup Language) for their product Earth Viewer, the format was adopted by Google for Google Earth, which was developed based on the Keyhole […]

Is there an OGC standard for map annotations?
There are two discussion papers heading into this direction that I know about (there might be more that I don’t […]
