Content

Contains georeferenced, manually digitized, fracture traces along with delineated target areas for them. Both are in GeoPackage databases. These can be opened with modern GIS-software, e.g. QGIS or analyzed in Python with e.g. geopandas or fracture network analysis toolkit fractopo.

See https://www.kaggle.com/nasurz/fracture-trace-visualization for a visualization of the traces.

Digitizing was done by two operators from Geological Survey of Finland, Nikolas Ovaskainen (Researcher) and Ismo Aaltonen (Senior Specialist).
