GeoProof

GPS Photo Proof for Home Inspectors

Your report is the product. Two hundred photos go into it, and every one of them is a claim: this defect, in this house, on this date. Six weeks after closing, a buyer emails asking why you never flagged the water damage in the basement — and the only thing standing between you and a long afternoon is whether your photos can say for themselves where and when they were taken.

For home and building inspectors

Three ways photos get you into trouble

Two houses from the same builder. You inspect a tract home on Tuesday and its near-twin three streets over on Wednesday. Same floor plan, same white kitchen, same panel, same furnace model. On a screen, those photo sets are indistinguishable. Anything that mixes them mixes them silently — you will not catch it by looking.

"You missed it." Sometimes the defect really is in your photo set, clearly shot, and the complaint dissolves the moment you produce the image with the address and the inspection date on it. Sometimes the condition genuinely appeared after you left — a leak that started in the six weeks between your visit and the buyer moving in. A dated photo of that ceiling, dry, is the difference between those two conversations.

The re-inspection. The seller repairs four items and you go back. Now you have two shots of the same corner of the same crawlspace and you need everyone to know which came first. Without a date on the picture, "before" and "after" is just the order you happened to paste them in.

What lands on each photo

Stamped at the moment of capture

  • GPS coordinates, and the accuracy the phone reached
  • Street address for those coordinates
  • Date and time, checked against a public time server rather than the phone's own clock
  • Compass heading and altitude
  • Weather at capture, optional and off by default
  • Your logo and the job name — the inspection address works well

Because it is drawn into the pixels, it survives the trip into your report software, out again as a PDF, and onward as a forwarded email or a screenshot on somebody's phone. Hidden EXIF data does none of that; most of the pipeline your report travels through will discard it.

Every photo also gets a SHA-256 fingerprint at capture, so you can re-check later whether that exact file has changed since it was taken. That is a change check on a file — no more than that. GeoProof does not certify anything and is not a legal service.

Walking an inspection

  1. At the kerb. Set the job name to the property address, then shoot the front of the house. That single photo, with the address on it, is what ties the rest of the set to a building.
  2. Exterior circuit. Grading, siding, flashing, roof from the ground. The heading on each shot tells you which elevation you were looking at when you write the report that evening.
  3. Systems. Panel, water heater, furnace, condenser — a wide shot for context, then the data plate, then the defect. Age and model come from the plate; the timestamp says when you read it.
  4. Attic and crawlspace. The nastiest photos and the most disputed ones. Shoot the access point first, then work in, so the report shows a path rather than a set of disconnected dark corners.
  5. Before you drive away. Export a PDF grouped by job, drop it into your report software as a photo appendix, and you are done with the sorting.

Under the house, and the accuracy number

GPS works off satellites, so no mobile data is needed for a position. But you spend a good part of the day inside a building — in a basement, an attic, under a floor — and satellite reception degrades badly under a roof and worse under earth. That is real, and it is not something an app can fix.

This is why the accuracy figure is stamped alongside the coordinates. A shot from the driveway may read a few metres; one from a crawlspace may read far worse, and the photo says so instead of quietly pretending otherwise. In practice, the exterior establishing shot is what pins the inspection to an address, and the interior photos sit under it in the same job.

The street address lookup is the other thing that needs a connection: on a vacant property with no signal you get coordinates immediately, and the street name fills in later once the phone is back in coverage.

Client property, on your phone only

No account, no cloud, no upload. Photos of the inside of somebody's home stay on your device — there is no GeoProof server holding them. Whatever leaves is what you deliberately export.
