- December 2006, another VTP visualization of the Lower Colorado River
Drainage Basin, by Jason Jessup

hydrology, population, land use and many other attributes. The area
covers most of what is Arizona.

- Virtual Philadelphia
- a detailed model of part of downtown Philly which was created for the center city business district by Israeli company GeoSim
- NY Times article "A 3-D View of the City, Block by Block" (Feb. 17 2005) has more details
- as of April 2008, GeoSim released a free standalone Windows app, GeoSimPHILLY which lets you walk/fly around the model
- The city model itself, while just a portion of downtown, is very detailed and visually impressive, showing a huge amount of work that went into the model. Potted plants and bicycles and dumpsters on the sidewalk, fire escapes on the buildings, every single store sign and awning meticulously modelled. The dynamic aspect, people and cars roaming the streets gives a sensation of reality. Address search and clickable buildings make it (potentially) useful beyond tourism.
- However, the camera navigation is painfully bad.
- Philadelphia has Philly Tree Map

- The official DC GIS
Data Clearinghouse/Catalog has a number of raw data layers

- The DC Data
Catalog seems to be another official data access site
- It contains links to some useful datasets including Street Trees
