Fracture patterns observed in the Jandaira carbonate formation (Potiguar basin, NE Brazil), digitised using a drone and manual interpretation in DigiFract software. These patterns are translated to a local coordinate system to allow for easier implementation in flow models, and each fracture has its attributes stored, including length, spacing, orientation and aperture calculated using different models. Data is stored in two formats: - Shapefiles (open with open-source QGIS, matlab shaperead, and several python modules including basemap). - Google kml files (open with Google Earth)
