Richmond’s MacDonald Dewittler, an information solutions company, has announced that the U.S. Department of Homeland Security (DHS) and Federal Emergency Management Agency (FEMA) have purchased a license for their National Urban Change Indicator, a system that uses satellite data to measure the human impact on locations over the past 25 years.

This is a development I’d like to see more coverage of in the coming months. Urban sprawl is a sad fact of life  in North America, and how we manage the spread of cities into our hinterland could be an essential facet of North American environmental policy.

Why isn’t Canada’s Environment Ministry using a system like this? Or the Americans’ for that matter? It could provide invaluable information about the past for the future.
