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. Prior to every analysis FracG will attempt to clean the vector data by removing duplicate entries and correcting flaws in the topology (e.g. merging points within a threshold distance).
The analyses performed by FracG include:
- Models of fault length distribution (optional) 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 different algorithms
- Betweenness Centrality (optional)
- Minimum Spanning tree
- Shortest path
- Maximum Flow
Analysis can optionally be extended by including raster data (e.g. DEM)
- Extraction of raster values along faults
- Augmenting the georeferenced graph by using raster data as edge and vertex weights
