Earth observation imagery

USGS Landsat Missions

U.S. Geological Survey / NASA
Scope

Long-term multispectral Earth observation data used for land-surface and post-fire analysis.

Strong use

Pre/post image comparison, vegetation change, burn indices, mapping context and reproducible remote-sensing workflows.

Evidence limits

Cloud, revisit time, pixel size, spectral response and processing level affect interpretation. Imagery is evidence, not a cause finding.

Source policy: Tecnobosque identifies what a source can support and what it cannot. A link to an authoritative source does not transfer authority to Tecnobosque and does not remove the need to preserve publication time, version and incident context.
