Sentinel-2 Imagery
The Sentinel-2 constellation delivers imagery refresh over the entire globe every five days. Imagery is collected at a resolution of 10 m for visible and near infrared (VNIR) bands. [caption id="attachment_6187" align="aligncenter" width="922"]

Merging Mid- and High-Resolution Imagery in SecureWatch
SecureWatch delivers Sentinel-2 imagery using Open Geospatial Consortium (OGC) protocols via Sinergise’s Sentinel Hub. In the SecureWatch interface, users control visualization of Sentinel imagery, Google and OpenStreetMap basemaps, and high-resolution DigitalGlobe imagery. They can also mix the layers to enable quick cross-referencing. These are the Sentinel-2 layers are now available in SecureWatch:- Latest SWIR Image
- Latest Natural Color Image
- Latest Color Infrared Image
- Cloudless Natural Color Image
- Cloudless NDVI Vegetation Index
- Cloudless NDWI Water Index
DigitalGlobe Imagery + Sentinel-2 Imagery = Better Informed Analysts
Use Case 1: Investigating Areas of Interest in Raqqa, Syria


- This Sentinel-2 SWIR image shows the Santa Rosa, CA wildfire on Oct. 10, 2017 in 20 m resolution. The burned part is brown and there’s a section of bright red (inside the yellow circle), which indicates this area is still hot and burning.
- Switching to DigitalGlobe’s WorldView-3 SWIR image at 7.5 m resolution, the highest resolution of SWIR imagery allowed to be commercially released by U.S. regulations, allows an analyst to further pinpoint the hotspot.
- The hotspot informs an analyst on where to request DigitalGlobe point its satellites to image the following day. This natural color image from Oct. 11, 2017 shows the area where the hotspot is located and what buildings have burned and still need to be protected.
- After the fire has moved away from the area, a follow-up image collection on December 1, 2017 indicates that firefighting efforts in this area succeeded at protecting buildings from being burned.
