Satellite · Ground · Public record
GroundAlpha watches 240 sites, starting with AI data-center campuses, from orbit, from the ground and from the public record. Every reading sits next to its source and its date.
Free to start: follow sites and get an email when a new pass, story or permit lands.
Evidence, not assertions
The same site, read two ways. Both halves below are live: a story published about a site we watch, and what we hold on it, each line dated.
What was reported
“Oracle issues force majeure notice to Blue Owl following series of setbacks at Project Jupiter data center campus – report”
A headline tells you what someone said. It rarely says when the site last looked like that.

Orbit
Sentinel-1 radar sees through cloud and at night. Each pass over a site is kept as a dated frame, and change is only measured between passes flown on the same orbit, so a new viewing angle never reads as new construction.
Ground
Vetted field scouts photograph sites on the ground. Every photograph carries where it was taken, which way it faced and when, and is reviewed before anyone sees it.
Record
County permits, parcel records, filings and news are tied to the same site and dated, so the frame and the record that explains it sit side by side.
Open to everyone
Public pages for sites we watch: the latest pass, the history on file and the latest news. No account needed.
Method
Each site is outlined from public sources such as permits, filings and facility records, and checked by an analyst before it is watched.
New radar passes are added as they land, and read against earlier passes from the same orbit.
Scouts photograph what the satellite cannot settle; news and county records are matched to the site as they appear.
Follow a site and get an email when a new pass, story or permit lands there. At most one a day.
Passes on file since Jan 2025. New readings land as the satellites fly over.
