LocatePic 3-Layer Cartographic Triangulation Methodology
LocatePic is engineered around a deterministic, auditable 3-layer spatial verification protocol. Rather than relying on opaque black-box guessing, every image or video keyframe is evaluated through binary header parsing, 5-node optical vector decomposition, and sovereign GIS topology alignment.
Hardware GNSS & Container Provenance
Before invoking optical inference, our browser-resident exifr and QuickTime parser inspects JPEG, HEIC, AVIF, WebP, PNG, TIFF, and MP4/MOV containers. It decodes IFD0 hardware tags, ExifIFD focal length and timestamp registers, GPSIFD (0x8825) DMS rational coordinates, and QuickTime ©xyz atoms with zero external network transmission.
Terrain, Infrastructure, Flora & Signage
When social compression strips EXIF tags, the image is decomposed into five orthogonal evidence vectors: 1) 30m SRTM DEM horizon curves, 2) Civil engineering specs (viaduct piers, guardrails, insulators), 3) Botanical species and bloom calendars, 4) Epigraphic script and phone prefixes, and 5) Meeus/NOAA solar shadow bearings.
Sovereign Matrix & Overpass QL Lock
Candidate regions are intersected against our 240-country driving handedness, ITU calling prefix, and live OpenStreetMap Overpass QL infrastructure graph—producing a weighted WGS-84 coordinate lock, UTM grid reference, and confidence radius.
