Online content contains only the most recent imagery, typically less than two years old. This imagery is orthorectified and pan-sharpened (MSI). Archived content includes “raw” imagery, older imagery (depending on the area, imagery dates can range back 5-10 years, and in some places more), and also the data contained in the online content. Images in the archive are displayed at lower resolution but are available for download at full resolution.
You can download the entire image strip, but it is not required. If you do not want to download the entire strip, you can optionally to clip images to a defined AOI (e.g., shapefile, drawn polygon, viewport extent, snapshot). See Ordering Archive Imagery.
All imagery in our online content is orthorectified, but users can access “raw” images from our archives.
Images average approximately 5m (CE90) based on location and NADIR.
The best available DEM is leveraged (typically SRTM30).
- NIR Approximately 2.4m GSD
- SWIR 7.5m GSD
- Yes. Snapshots saved as anything other than PPT or JPG are geo-referenced.
- Snapshots are full spatial resolution, but not full spectral resolution. For all MSI bands, you must pull the raw image from the archive.
Imagery can be downloaded in geographic or UTM projections.
