Historical geological maps were vectorized, projected and integrated into a digital geoscience database for mineralization research, landmass reconstruction and industrial analysis.
The challenge
Antiquated map formats were difficult to combine with modern GIS and geological analysis workflows.
World-scale projection created distortion risks near polar and equatorial regions, while the maps also carried dense geological attributes.
The approach
SBL vectorized landmass, sedimentation and orogeny layers while preserving projection accuracy.
The team integrated geological samples, groundwater contours and chemical signatures into a structured spatial model.
Assess
Review map eras, projections and geological feature types.
Vectorize
Convert landmass, sediment and sample features into digital layers.
Integrate
Normalize attributes for geoscience search and analysis.
The result
The client gained a digital geoscience layer that could support historical reconstruction and mineral exploration analysis.
- Old physical maps became usable GIS layers.
- Projection handling protected critical spatial relationships.
- Disparate geological attributes were brought into one model.
- The database supported research and industrial analysis paths.
