🎯 Build an ODM GCP file β€” click for instructions

1) Load your drone photos (they stay on this device β€” nothing is uploaded) Β· 2) Import surveyed points from an Emlid Flow CSV/DXF (or add manually) Β· 3) Select a point, then click its target in every photo where it's visible (β‰₯ 5 photos recommended, nadir + oblique) β€” use the πŸ—Ί Map to see which photos were taken near each point Β· 4) Export gcp_list.txt and feed it to ODM / WebODM. Before flying, open the ✈ Flight area tab to draw the mission area on a full-screen map and download it as a KML for a DJI Pilot 2 mapping mission β€” no photos needed. Points, tags, the flight area and the chosen CRS are kept in this browser between sessions; photos are re-loaded each time.
