There are publicly defined GIS data formats such as KML (Keyhole Mapping Language, from Keyhole, which became Google Earth when purchased by Google). There are also several Free Software GIS packages and display libraries that use neither flash nor java. We can combine data in usable formats with usable software to do whatever we need. Undoubtedly a few more converters are needed, but we can invite in people who are already doing that. Or we can go to their sites, as I have done at http://isde5.pbwiki.com/Earth_Treasury/. * gdal map file conversion * grass Geographic Resources Analysis Support System * qgis GIS that can use GRASS data See also Open Geospatial Consortium http://www.opengeospatial.org/ The Open Geospatial Consortium, Inc.(R) (OGC) is a non-profit, international, voluntary consensus standards organization that is leading the development of standards for geospatial and location based services. It is true that there are hundreds of proprietary or undocumented mapping formats, and lots of proprietary mapping software, but we don't have to bother with them. There are also lots of GIS file converters. Ray Cromwell tells me that Timepedia is putting a lot of effort into translating publicly available map data files to widely usable formats and adding necessary metadata. http://www.timepedia.org <--not .com Timepedia started with a simple question: "What if we could collect all historical data and help everyone explore and understand it?"
