Map Marker Extractor

Screenshot → calibration → geo-located markers. Runs entirely in your browser.

1. Screenshot & calibration points
Upload or paste a screenshot to begin.

Tip: press Ctrl/Cmd+V anywhere to paste a screenshot.

2. Reference points

Click on the screenshot to drop a reference point. Type, paste, or pick its coordinates. 1–2 well-spread points suffice for clean maps; use 4+ for scans or photos.

No reference points yet. Click anywhere on the image.
3. Detect markers

Most reliable. Turn on, click every pin on the screenshot, then run detection.

Pick one well-formed marker per color/shape variant; detection tightens to match.

4. Results & export
Output coords:
Add at least 2 reference points with coordinates to project detected markers to real-world locations.
