FracG UI

FracG is a tool for analysing discontinuity data (e.g. faults and fractures). The input is provided as line-vector data in shapefile format.

The analyses performed by FracG include:

• Models of fault length distribution and principal orientations
• Statistical parameters including scan line analysis
• Box-counting to obtain fractal dimension
• Maps of fault density, intensity, distance to faults
• Classification of faults (orientation, intersection numbers)

FracG is able to construct georeferenced graphs and apply various algorithms to them, including:

• Betweenness Centrality
• Minimum Spanning tree
• Shortest path
• Maximum Flow

Analysis can optionally be extended by including raster data (e.g. DEM), for example:

• Extraction of raster values along faults
• Augmenting the georeferenced graph by using raster data as edge and vertex weights
