Google maps is the MP3 of GIS
Google maps, ZoomIn maps and et are like the MP3 of the GIS world. It has made mapping and spatial visualisation available to everyone with a browser. Just as MP3 maybe not be good enough for audiophiles, google maps is not going to be powerful enough for a lot of serious GIS work. The simplicity of Google maps is going drive the consumption of GIS information into a new era.
