Dataset Information

Point cloud data derived from Pleiades imagery of the Bilila-Mtakataka Fault, Malawi. The bi-stereo Pleiades imagery (50 cm pixel-1) was processed using the Leica Photogrammetry Toolbox within ERDAS Imagine. Point Cloud data was prepared for Open Topopgraphy using PDAL. Processing was carried out by Michael Hodge (University of Cardiff, now at Office for National Statistics, UK) and Austin Elliot (University of Oxford), supported by Juliet Biggs (University of Bristol) and Ake Fagereng (University of Cardiff). Luke Wedmore (University of Bristol) prepared the files for upload.

The Imagery was purchased using a small grant from COMET (Centre for Observation and Modelling of Earthquakes, Volcanoes and Tectonics). Michael Hodge was supported by the NERC GW4+ Doctoral Training Partnership (NE/L002434/1) and COMET. Austin Elliott was supported by COMET and NERC Large Grant Looking into the Continents from Space(LICS; NE/K011006/1). Luke Wedmore was supported by EPSRC Global Challenges PREPARE project (EP/P028233/1). Juliet Biggs was supported by LICS (NE/K010913/1) and PREPARE(EP/P028233/1). Ake Fagereng was supported by PREPARE (EP/P028233/1).
