FREE NASA’s new Remote Sensing Toolkit for Startups

There are dozens of websites that NASA uses to host its remote-sensing data and tools (more than 50, we kid you not!). So, for someone not too familiar with the geospatial industry, making sense of all this information or even figuring out which asset can be located where could be an overwhelming exercise. Not surprisingly, NASA has not been able to make startups or other small businesses tap into its full commercialization potential, even though these companies could benefit greatly from access to free and open remote-sensing data.

The Landsat program is the longest-running enterprise for acquisition of satellite imagery of Earth. On July 23, 1972 the Earth Resources Technology Satellite was launched. This was eventually renamed to Landsat. The most recent, Landsat 8, was launched on February 11, 2013. The instruments on the Landsat satellites have acquired millions of images. The images, archived in the United States and at Landsat receiving stations around the world, are a unique resource for global change research and applications in agriculture, cartography, geology, forestry, urban and regional planning, surveillance and education, and can be viewed through the USGS ‘EarthExplorer’ website. Landsat 7 data has eight spectral bands with spatial resolutions ranging from 15 to 60 meters; the temporal resolution is 16 days. Landsat images are usually divided into scenes for easy downloading. Each Landsat scene is about 115 miles long and 115 miles wide (or 100 nautical miles long and 100 nautical miles wide, or 185 kilometers long and 185 kilometers wide).
