Free Landsat Downloads Hit Half Million
- Apr. 2 • On April 2, 2009, the U.S. Geological
Survey (USGS) Landsat Project delivered its 500,000th free image
for Fiscal Year (FY) 2009. A recent USGS policy change enabled Landsat
data to be distributed at no charge via the internet. Prior to the
policy change, the highest year of distribution was in FY2001 when
approximately 25,000 scenes were delivered. This phenomenal increase
in distribution comprises an estimated 95 TB of data downloaded by
users. Although the USGS does not have detailed records since the
mission's inception in 1972, there is good evidence that more data
have been distributed in the last 6 months than in the entire first
36 years of the Landsat missions combined.
