LandSat at 40

LandSat imagery was the first example we saw of the value of images from space for business.  We examined them for use in forest management for the pulp industry.  Now Google Latlong has an excellent overview of what this data has meant, and links to a number of resources available, including some new ones they have put together.  We have come a long way in resource imagery,  and this was an excellent and inspirational start.
