In the Feb/Mar 2009 issue of GeoConnexion magazine, David Maguire talks about the future of spatial analysis, 3D tools, and temporal analysis.
“There are several key developments that need to be put in place in order for 3D and 4D GIS to become more popular. Current data modes are adequate for basic 3D work, but need to be extended into the temporal domain. We have basic analytical operations, but more work is needed on true 3D (volumetric analysis) and 4D analysis. Visualization is adequate for small to medium sized static data sets, but significant breakthroughs are required for large dynamic data sets.”
