Matt Fox, who georectified the Great Salt Lake bathymetric maps for use as Google Earth overlays, has made available his entire collection of maps through a Google Earth network link. The collection includes topo maps of the western U.S.,…
Microsoft Mapping Roundup
Chandu Thota is leaving the Virtual Earth/MapPoint group to join another group within Microsoft. He’s been there four years, during which time we heard about a good deal of his work. For example, some previous entries: Thota on Virtual Earth…

e_Perimetron
e_Perimetron is a new quarterly web journal, the focus of which is the application of geospatial technologies to old maps. The first issue, for example, has articles that transform old maps to conform to known coordinates, assign projections to portolans,…
A Microsoft Roundup
Jeff Thurston thinks that MapCruncher (see previous entry) is “innovative”: “It would be interesting to see ‘artistic’ mapping using MapCruncher — personal mind maps, etched drawings, action/reaction layers and other kinds of unique maps created with this product. In other…
MapCruncher
MapCruncher is this new thing from Microsoft Research that uses the Virtual Earth API (I guess it’s Virtual Earth for the technology, Windows Live Local for the online mapping site) to integrate your own maps into their system: Once you…
