Terrascope is a Google Earth implementation of the LANDSAT MSS, TM and ETM+ ortho mosaics for the 1970s, circa 1990 and circa 2000. It is designed to allow rapid comparison of LANDSAT imagery between these periods for any view in Google Earth. The imagery is provided as superoverlays in which resolution (level of detail) increase as you zoom in on an area. Full resolution is 57 metres/pixel for the 1970′s (MSS), 28.5 metres/pixel for the circa 1990 (TM) and 14.25 metres/pixel for circa 2000 (ETM+). The rationale for terrascope is to provide an easy mechanism for visual change detection for non remote-sensing specialists who may be interested in environmental change research (desertification, land use change, urbanisation, coastal fluvial and water body change), awareness raising (of hotspots for habitat loss for example), and conservation monitoring or prioritisation uses.

Mapping the DuBois Philadelphia Negro is a recent project housed at the School of Design at the University of Pennsylvania and aimed at recreating the survey W.E.B. Du Bois conducted in 1896 that served as the basis for his 1899 classic, The Philadelphia Negro. Data will be mapped and analyzed using GIS and spatial statistical methods and used as the basis to addressing the following questions:
- How did DuBoisâ€™s research methods reflect and influence developments in the social sciences and social survey movement?
- What was the basis for his class grades?
- What was the nature of residential segregation in 1896 by race, ethnicity, and migration status?
- What happened to the Black residents and Black institutions of the 7th Ward during the 20th Century?
- How did housing conditions in Philadelphia compare with housing conditions in New York and other cities?
