Earthdata SearchEarthdata Search allows you to search, discover, visualize, refine, and access NASA Earth Observation data.
EarthExplorer (USGS)EarthExplorer provides access to one of the largest civilian remote sensing data archives. It contains a comprehensive record of the Earth’s changing land surface to conduct research on changes that affect our environment, resources, health, and safety. Time series images are a valuable resource for scientists, disaster managers, engineers, educators, and the general public.
esa: EARTH ONLINEFree online images and datasets from ERS and Envisat missions related to atmospheric chemistry, altimetry, (A)ATSR, MERIS, and a subset of the SAR data, and The Earth Explorer missions. Requires on-line registration. Delivered through the European Space Agency.
Global Land Cover Facility (GLCF)Provides earth science data and products to understand global environmental systems. Develops and distributes remotely sensed satellite data that explains land cover. Free to anyone using FTP. Online datasets may be accessed electronically through the Earth Science Data Interface (ESDI).
Global Visualization ViewerAllows for accessing remote sensing data. You can view and download worldwide satellite imagery from the USGS.
Landsaat (USGS)Represents the world’s longest continuously acquired collection of space-based moderate-resolution land remote sensing data. Four decades of imagery provides a unique resource for those who work in agriculture, geology, forestry, regional planning, education, mapping, and global change research. Landsat images are also invaluable for emergency response and disaster relief.”
National Atlas programThe former National Atlas program was removed from service in 2014. Some of its previous products and services are available from the following USGS sources at this link.
