View Our Changing Earth: Esri Provides Free Access to More than 8 TB of Landsat Satellite Data + 2 Online Viewers
In 2008, the secretary of the US Department of the Interior (DOI), Dirk Kempthorne, addressed the audience at the Esri International User Conference and announced that as part of a larger US government initiative to make its data more available, all Landsat scenes in its archives would be available for free. This includes the Landsat Global Land Survey (GLS) datasets, which provide the best worldwide imagery data for how our earth is changing. Last year, Esri announced that it would make this imagery data accessible for free on ArcGIS Online.
Working in close collaboration with DOI, Esri is pleased to announce the release of the Landsat imagery services. These image services enable fast and easy access to 30 years of Landsat imagery as part of ArcGIS Online. Esri is providing this data (more than 8 TB) on ArcGIS Online and serving it as over 20 different dynamic, multispectral, multitemporal image services that provide access to the full image information content, along with change detection capabilities. In addition, Esri has created web maps and an interactive web application that leverage these image services, providing even greater access.
