One of the difficulties faced by teams responding to the current Ebola outbreak in West Africa is identifying individuals and communities residing in remote areas. Existing maps of these regions either do not exist or are inadequate or outdated. This means that basic data like location of houses, buildings, villages, and roads are not easily accessible, and case finding and contact tracing can be extremely difficult.

To help aid the outbreak response effort, volunteers from around the world are using an open-source online mapping platform called OpenStreetMap (OSM) to create detailed maps and map data of Guinea, Sierra Leone, Liberia, and parts of Mali.

Those answers can be found online using the U.S. Energy Information Administration's interactive U.S. Energy Mapping System, which shows all the major energy infrastructure for any given address in the U.S.

DETROIT — A midnight blue Chevy rolls slowly down a snow-covered street, an emergency strobe light on its roof and a sign on its side that promises this is “official business.” At each house, business, even vacant lot, workers in the car pause to decide whether someone lives there and what shape the place is in before snapping a photo and beaming it to “mission control” miles away.

All over Detroit, scores of these workers — on some days as many as 75 three-person teams — have been wending their way through the streets since December, cataloging on computer tablets one of this bankrupt city’s most devastating ailments: its tens of thousands of abandoned and dilapidated buildings.
