Any map. Any projection.
Georeferenced automatically.
Upload a scanned geological, topographic, or legacy map. Monarcha identifies the coordinate system, matches control points, and georeferences in seconds, not hours.

Layers
Fast processing
Upload a scan and get a georeferenced output in seconds, not hours.
High accuracy
AI-matched control points deliver results that rival manual GCP placement.
Broad projection support
UTM, state plane, local mine grids, and thousands of EPSG codes.
Automatic GCPs
Control points are identified and matched without manual intervention.
Any map, any projection
Geological surveys, topographic sheets, mine grids, legacy cadastral maps. Monarcha identifies the coordinate system and transforms automatically. Supports UTM, state plane, local mine grids, and 4,000+ EPSG codes.
Also works with the Digitizer →Detected projection
Automatic control-point matching
AI-driven feature detection identifies grid intersections, marginal notations, landmark features, and text labels to compute accurate ground control points. Most maps need zero manual adjustments.
Control points
Flexible output formats
Export as GeoTIFF, Cloud-Optimized GeoTIFF, or bring results directly into ArcGIS, QGIS, or Leapfrog. Full CRS metadata preserved. Batch processing handles hundreds of maps at once.

How it works
Three steps from a paper scan to a spatially-accurate digital layer.
Upload your scan
Drag and drop a scanned map in TIFF, PNG, JPEG, or PDF format. Batch upload is supported.
AI identifies the projection
Monarcha reads marginal notations, grid ticks, and map metadata to determine the CRS.
Review and export
See the overlay on a satellite basemap. Adjust control points if needed. Most maps require no edits.
