Before-and-After Satellite Reports
A dated, independent satellite record of what changed on a site between any two dates. Built for developers, owners' reps, site teams, buyers, and lenders who need to prove what happened and when.
On a development or construction site, the most expensive arguments are about what happened and when. Was that slope cleared before or after the permit? Did the contractor grade what the schedule says they graded? What did this parcel look like the day before you bought it? Construction and Land Change Detection settles those questions with evidence. We compare satellite imagery from any two dates you choose and lay the site out side by side, with a plain-language paragraph under each image explaining exactly what moved: grading, clearing, stockpiles, and new construction. The result is a dated, third-party record you can drop into a permit file, a closing, a draw request, or a dispute, produced without putting anyone on-site. For an owner's rep or a civil team, it is a way to verify progress between site visits. For a buyer or lender, it is due diligence you can defend. For anyone who has ever been on the wrong end of a he-said-she-said over a site, it is the receipt.
