Spectrometry-derived Ecosystem Composition

Imaging spectrometry was used to provide spatially-comprehensive measurements of plant functional type (PFT) composition across a functionally diverse and topographically heterogeneous ~710km2 area in the Southern Sierra Mountains of California.

Global Spatio-Temporal Search: NEH Funded Enhancements to WorldMap

Though millions of geo-service layers exist just a click away, there is no good way to discover most of them. In the early days of the web it was hard to find a web page; this situation holds today for most geo-data.

With a grant from the National Endowment for the Humanities, the CGA is building a platform to create, maintain, and deploy a global public registry of web map services, and has developed a new visual interface to support searches by time and space.  The technology can scale to millions, even billions of objects.

Temporal Gazetteer

The Temporal Gazetteer (TGAZ) is a search engine and machine-readable API for historical placenames.  Built upon toponymic databases of historical placenames from the China Historical GIS, the Toponimika - Historical Gazetteer of Russia, and the Gazetteer of Historical Monasteries in Greater Tibet, the TGAZ system architecture provides a method for integrating historical plac

China Historical GIS

The CHGIS project has produced a comprehensive series of datasets related to the administrative geography of Chinese History. The data layers include nationwide coverages (for the years 1820 and 1911), and time series (for the Dynastic period from 221 BCE to 1911 CE). The administrative features include Provinces, Circuits, Prefectures, and Counties as they changed over time. Supplemental datasets include G.W. Skinner regional systems, Buddhist sites, features from historic Russian maps of China, Tibetan townships, modern gazetteer layers for each province, and many others.

Mapping for the Out of Eden Walk project

The Out of Eden Walk is a 21,000-mile journalistic endeavor to create a global record of human life at the start of a new millennium as told by villagers, nomads, traders, farmers, soldiers, and artists who rarely make the news.  Sponsored and hosted by National Geographic, the project is led by Pulitzer Prize winning writer Paul Salopek who is walking the path of human migration across the globe, and recording what he encounters in the form of writing, photographs, video, and audio.
