A discussion of crowdsourced geographic information initiatives and big Earth observation data architectures for land-use and land-cover monitoring
Posted in Publications, VGI Group on Jun 3rd, 2018
The effective monitoring of land-use and land-cover changes (LULCC) is a basic requirement for understanding socio-enviromental processes of local to global scales. Remote sensing data and methods have long been established as the most effective approach for monitoring LULCC. The potential for further increasing the effectiveness of this approach is proportional to the astonishingly large [...]

3D micro-mapping: Towards assessing the quality of crowdsourcing to support 3D point cloud analysis
Posted in Lidar Group, Publications, VGI Group on Feb 19th, 2018
Crowdsourcing has been widely applied to extract information from 2D geodata sources such as satellite imagery. In this new study published in the ISPRS Journal of Photogrammetry and Remote Sensing we apply this technique to the growing field of 3D point cloud analysis. This work has been conducted in our 3D-MAPP Project which was funded [...]
