Commuter Megaregion`

The Megaregions of the US

Garrett Dash Nelson

Every day, hundreds of millions of commuters weave more than 4 million threads connecting more than 70,000 Census tracts in the contiguous United States. These threads provide evidence for a new functional geography of the continent—based not on state or city lines, but on megaregions of vast areas connected by deep economic ties. By subjecting these connections to an algorithm which detects natural groupings in large data sets, we can define a mosaic structure of regions which cut interestingly across our familiar map of the country. Looking at the US in this new way helps us to reorient ourselves in terms of the ways that people are spatially connected in the twenty-first century.

 Nick Camerlenghi

This website offers virtual access to a premier collection of 4,000 curated and cataloged historic depictions amassed by Rodolfo Lanciani (1845–1929), a pioneer in the systematic, modern study of the city of Rome. The project is a collaboration of Dartmouth College, University of Oregon, Stanford University and Istituto Nazionale di Archeologia e Storia dell’Arte in Italy, which houses the images.

The CORONA Atlas Project

Since its declassification in 1996, Cold War-era CORONA satellite imagery, collected from 1960-1972 as part the world’s first spy satellite program, has proven to be an extraordinarily powerful resource for archaeology and other disciplines. Because the imagery pre-dates the dramatic land use changes that have come with urban expansion, industrialization, and agricultural intensification in recent decades, it preserves a view of countless archaeological sites and other landscape features that have been destroyed or obscured by modern development. Furthermore, because CORONA offers the only source for global-scale, historic, high-resolution imagery, it is a critical tool in studies of environmental, land use, and urban transformation.
