Deep residential representations: Using unsupervised learning to unlock elevation data for geo-demographic prediction [article]

Matthew Stevenson, Christophe Mues, Cristián Bravo
2021 arXiv   pre-print
LiDAR (short for "Light Detection And Ranging" or "Laser Imaging, Detection, And Ranging") technology can be used to provide detailed three-dimensional elevation maps of urban and rural landscapes.  ...  However, the geographically granular and open-source nature of this data also lends itself to an array of societal, organizational and business applications where geo-demographic type data is utilised.  ...  Acknowledgements The authors acknowledge the use of the IRIDIS High Performance Computing Facility, and associated support services at the University of Southampton, in the completion of this work.  ...
