Mapping Rohingya Refugee Camps in Bangladesh – An Analysis Using the OSHDB API
Humanitarian mapping activations show increasing numbers of contribution. This blog post illustrates the specific potential of the Open Source OSHDB API [1] for detailed analyses of such activations by means of a case study. The examined area is Cox’s Bazar in Southeast Bangladesh, where almost 1 million Rohingya refugees fled to from Myanmar in 2015.…

4D objects-by-change: Spatiotemporal segmentation of geomorphic surface change from LiDAR time series
How can surface change processes be detected and delineated in large time series of 3D point clouds? A paper on the extraction of 4D objects-by-change has just been published in the ISPRS Journal of Photogrammetry and Remote Sensing. It presents an automatic method for 4D change analysis that includes the temporal domain by using the…

The Importance of Monitoring Interval for Rockfall Magnitude‐Frequency Estimation
Rockfalls commonly exhibit power law volume-frequency distributions, where fewer large events are observed relative to more numerous small events. Within most inventories, the smallest rockfalls are the most difficult to detect and so may not be adequately represented. A primary challenge occurs when neighboring events within a single monitoring interval are recorded as one, producing…
