Turn Your Maps Into GIS Data

Send Eigenform a scanned geological map and get back clean, georeferenced GIS data: polygon geometry, shapefiles and GeoJSON, ready to drop into your workflow. Flat rate, two working days.

From Scan to Structured Data

Our production map pipelines turn hand-drawn and printed geological sheets into clean polygon geometry with contacts closed, units separated, and the legend read off the margin and joined back onto the shapes it describes. The sheet is georeferenced from its own graticule and corner ticks, and comes back as shapefile and GeoJSON in whatever projection your software expects.

See our worked example in the Kyrgyzstan Soviet-era map vectorisation case study, powered by our Geocluster tools.

What We Deliver

• Polygon geometry: Closed, topologically clean unit boundaries resolved from cross-hatched units and annotation-broken contacts.
• Shapefile & GeoJSON: Georeferenced vector layers delivered in the coordinate reference system (CRS) your GIS workflow requires.
• Attributed units: Map legend extracted from the sheet margin and joined directly to the corresponding polygon geometry.
• Linework layers: Structural faults, geological contacts, and fold axes separated into dedicated queryable layers.

Automated Quality Control

Every extracted value and polygon boundary is verified against the source sheet, flagging topological gaps, unclosed contacts, and legend mismatches before delivery. Need custom enterprise workflows? Contact Eigenform or explore Eigenform AI.
