To assess the uses and value of Landsat imagery, social scientists at the USGS Policy Analysis and Science Assistance Branch (PASA) of the Fort Collins Science Center are conducting a long-term study of Landsat imagery users. A series of surveys provides longitudinal data on how the users and uses of the imagery are changing over time in response to changes in the provision of the imagery. The 2012 survey was completed by over 11,000 people registered as Landsat users with USGS. The results show that Landsat imagery is applied in projects at all scales around the globe by users in all sectors. Landsat imagery is highly valued by these people, who identified considerable economic benefits from the use of the imagery. Also in 2012, case studies focusing on the use of Landsat imagery in water, forestry, and mineral and energy exploration applications provided an in-depth look at the market and non-market value of the imagery. These efforts document the widespread and increasing use and value of Landsat imagery.
