The LandsatLook Viewer is a prototype tool that was developed to allow rapid online viewing and access to the USGS Landsat image archives. This viewer allows you to:
Interactively explore the Landsat archive at up to full resolution directly from a common Web browser
Search for specific Landsat images based on area of interest, acquisition date, or cloud cover
Compare image features and view changes through time
Display configurable map information layers in combination with the Landsat imagery
Create a customized image display and export as a simple graphic file
View metadata and download the full-band source imagery
Landsat 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.
The Landsat Update is an informal communication tool, prepared periodically and distributed electronically to USGS Landsat partners, to provide information about Landsat activities and related topics of interest.
