Precision Geocoding & Mapping (Location Tab)¶
The map uses OpenStreetMap tiles for street view and Esri / ArcGIS imagery for satellite view; attribution is shown in the map's bottom-right. Address search is handled by MapTiler with an automatic fallback to OpenStreetMap Nominatim.
Smart Search & Paste¶
- Address search: type any address or landmark to fly the map there.
- Smart Paste: paste GPS coordinates from almost any source:
- Google Maps URL: right-click a point and copy the link.
- Decimal pair: e.g.
45.5231, -122.6765. - DMS (degrees/minutes/seconds): e.g.
40°42'46.0"N 74°00'21.6"W.
Formats not supported
Plus Codes (OLC) and what3words strings are not currently recognised. Convert to decimal first.
Workflow Power Tools¶
- Pin to map: save a photo's location as a temporary reference pin.
- Last used: instantly re-apply the most recently used coordinates.
- Clear location: strip the current GPS coordinates (staged; not committed until you write changes).
- Location Presets: save named coordinates (e.g.
Home Studio,Gallery East Pier) for one-click reuse. Presets are stored locally in your browser and remain available across sessions on the same device.
GPX Track Sync¶
Import a .gpx log recorded on a GPS handheld or with the Mobile GPS Field Logger.
- Scope: Run Match operates on every photo in the gallery, not just your current selection.
- Time Offsets: correct for a camera clock that drifted from UTC. Jade GT also supports per-camera offsets when a shoot mixes bodies with different clock settings. The matcher applies the right offset to each photo based on its camera identity.
- Match Window: default is 30 minutes; the threshold is a slider in the Match Preview. Tighten to 1 to 2 minutes for dense logs, or widen if your camera clock was badly out. Photos outside the window are flagged as unmatched and keep their original GPS.
- Matching algorithm: Jade GT picks the single closest GPX point by timestamp. It does not interpolate between track points, so matches are as accurate as your GPX sample rate.
- What gets written: only latitude and longitude. Altitude, heading, and speed captured by the Logger are not written to EXIF.
What the Match Preview shows
After clicking Run Match, the preview shows a card per photo with:
- Old vs New coordinates.
- Time delta to the matched GPX point.
- Filter (All / Matched / Unmatched) and sort (Time Delta / Filename) controls.
- Per-card checkboxes: tick the cards you want to apply before confirming.
- If many photos come back unmatched, the preview shows a Fix Clock shortcut that jumps you straight to the offset workflow on the Logger page.
What the GPX parser reads
Jade GT parses <trkpt> (track points) and <wpt> (waypoints). <rtept> route points and GPX extensions (including speed, cadence, heart-rate fields) are ignored.
