Geotag Photo Report (site-visit and inspection PDF with map points)

About the Geotag Photo Report (site-visit and inspection PDF with map points)

Turn the photos of a site visit into a PDF report: a cover with the project, site, client, inspector and summary, a sketch of where each photo was taken, then every photo with its number, time, coordinates and accuracy, altitude and direction where recorded, Plus Code, a clickable map link, your note and the photo’s SHA-256 fingerprint. A photo list and a fingerprint table close the report.

With a pass, the same points download as CSV (for Excel or Google Sheets), KML (Google Earth, QGIS) and GPX (GPS and mapping apps), and a ZIP holds the original photos, the PDF, the point files and a SHA256SUMS.txt file for checking every photo at once. It works with photos from GPS Map Camera — whose Make a site report button sends a session straight here — and with photos from any phone camera that saves the location. Everything is made in your browser; photos and locations are never uploaded.

Common uses

• Construction and maintenance inspections, snag lists and progress reports.
• Field verification for surveys, utilities, agriculture and insurance claims.
• Real-estate and valuation visits that need a record of where each photo was taken.
• Handing over photo points to a GIS team as KML or GPX.

What the report contains

• Cover: title, project, site, client or reference, inspector, organisation, the time span of the photos, how many have a location, the centre of the points and the distance between the farthest two, your summary, and when the report was made (the device time).
• Sketch of the points: each located photo as a numbered dot at its true position — north up, to scale, with a scale bar and a shaded circle for its accuracy. It is not a map: no streets or buildings are drawn, and nothing is fetched from a map service.
• Photo pages: two or four photos per page, each with its number, file name, time with UTC offset, latitude and longitude with accuracy, altitude and direction when the camera recorded them, Plus Code, a map link you can click in the PDF, your note and its SHA-256 fingerprint.
• Photo list and fingerprint table at the end, for quick reference and checking, and sign-off lines for the inspector’s and the reviewer’s name, signature and date (you can leave them out).

The point files

• CSV: one row per photo with local time, UTC offset, UTC time, latitude, longitude, accuracy, altitude, direction, Plus Code, map link, note and fingerprint — UTF-8, opens in Excel and Google Sheets.
• KML 2.2 (OGC KML): one placemark per located photo with its number, time and description, for Google Earth, Google My Maps and QGIS.
• GPX 1.1 (Topografix GPX): one waypoint per located photo, times in UTC as GPX requires, with a link to the photo file in the ZIP.
• SHA256SUMS.txt (in the ZIP): every photo’s fingerprint in the format sha256sum -c SHA256SUMS.txt checks.

What the fingerprints show — and what they do not

A SHA-256 fingerprint (FIPS 180-4) changes completely if a single byte of a photo changes. Listing them lets anyone confirm later that a photo file is exactly the one in the report: compute its SHA-256 (sha256sum on Linux, shasum -a 256 on macOS, certutil -hashfile photo.jpg SHA256 on Windows) and compare.

The fingerprints are not signed by anyone, so they detect accidental changes and mix-ups only — someone who edits a photo can also make a new report. Locations and times are what the camera device recorded and can be wrong, or overridden by location-spoofing apps. The report says so on its cover.

Where the details come from

Everything is read from the Exif data in the photos: DateTimeOriginal with its offset (or, when a camera writes no offset, the offset implied by the GPS time stamp), the GPS position, GPSHPositioningError (accuracy), altitude and image direction, and the image description as the note. Photos taken with GPS Map Camera also carry the result of its clock check, which the report prints. Nothing is looked up online.

Limitations

• Up to 200 photos of up to 60 MB each per report; the photos, the PDF and the ZIP are made in your browser’s memory.
• HEIC photos can be listed everywhere, but only browsers that open HEIC (Safari) can put their pictures in the PDF; convert them with the HEIC to JPG converter first in other browsers.
• Notes in scripts that need shaping, such as Devanagari, Tamil or Arabic, are drawn into the PDF as pictures by your browser, so they look right but cannot be searched or copied as text.
• No street addresses and no map backgrounds: both would need an online map service. The map links open the exact point in Google Maps or OpenStreetMap.
• Nothing is saved between visits except the inspector, organisation, logo and layout choices: download the PDF or ZIP before you close the page.
