SkyTruth
Came across this site a while ago, and I really think this can be a vital resource:
A picture is worth a thousand words. SkyTruth uses pictures taken from orbiting satellites and aircraft to show people the impacts of our activities on the planet.
These images reveal the landscape disruption and habitat degradation caused by mining, oil and gas drilling, deforestation and urban sprawl. And because satellites have global reach and can repeatedly capture images of any area, they can be used to monitor industrial sites, logging operations, environmentally sensitive areas, shipping traffic, fisheries, and resource-management practices no matter where in the world they occur. With a global archive of satellite images now stretching back more than 30 years, we can also use current and historical images to show changes in the landscape over time.
At SkyTruth, we specialize in designing and conducting projects that use images to study and communicate environmental impacts. Our technical staff uses advanced image processing techniques to turn raw image data into a wide range of useful products, including large-format maps and posters, page-sized brochures and flyers, virtual globes (Google Earth) and Web-friendly digital graphics. We also provide custom-processed images in digital formats compatible with the most widely used Geographic Information Systems (GIS) software. </em>
Fascinating- and very needed- stuff.
