My sister Janice in Edmonton sent me an interesting article from the BBC on how new satellite mapping technology is helping out after Katrina in New Orleans. Be sure to check out Tim Holtt's before and after images on the right-hand side of the page for some amazing before and after shots of parts of the affected area. Just move your cursor over the picture to watch it change.
Janice is a GIS (Geographic Information Systems) analyst with The Forestry Corp and she uses a lot of satellite imagery and analysis in her work. So this is of particular interest to her and her colleagues.
Thanks to Janice for the link.
