Fault database for the George and NE Edward Rifts, Uganda

<p>This database is associated with a master's research project at the University of Bristol. The initial geospatial database documents the geometry of 152 faults identified through digital mapping, along with associated attributes. This represents the first detailed fault mapping conducted in the area. The version of record is in .geojson format, however data is also available in .kmz and .shp formats. Attributes are adapted from Williams <em>et al. </em>(2022) and the Global Earthquake Model Global Active Faults Database (GEM-GAFD; Styron & Pagani, 2020).</p> <table> <caption>List and brief description of the attributes in the fault database ('EGR_faults')</caption> <thead> <tr> <th scope="col">Attribute</th> <th scope="col">Data Type</th> <th scope="col">Description</th> <th scope="col">Notes</th> </tr> </thead> <tbody> <tr> <td>FAULT_ID</td> <td>integer</td> <td>Unique numerical reference ID</td> <td> </td> </tr> <tr> <td>CONFIDENCE</td> <td>integer</td> <td>Certainty of whether the fault exists there</td> <td>1 = moderate, 2 = high</td> </tr> <tr> <td>FAULT_NAME</td> <td>string</td> <td>Name of fault</td> <td>Not all faults are named.
