Dinger, Florian; Kleinbek, Timo; Dörner, Steffen; Bobrowski, Nicole; Platt, Ulrich; Wagner, Thomas; Ibarra, Martha; Espinoza, Eveling, 2021, "SO2 and BrO emissions of Masaya volcano from 2014 to 2020 [Research Data]",, heiDATA, V1, UNF:6:VbhqF5vB+XRklpsSgIST5A== [fileUNF]
EXCERPT FROM ABSTRACT: Masaya (Nicaragua, 12.0°N, 86.2°W; 635m a.s.l.) is one of the few volcanoes hosting a lava lake, today. This study has two foci: (1) discussing the state of the art of long-term SO2 emission flux monitoring with the example of Masaya and (2) the provision a...

Winiwarter, Lukas; Anders, Katharina; Zahs, Vivien; Hämmerle, Martin; Höfle, Bernhard, 2021, "M3C2-EP: Pushing the limits of 3D topographic point cloud change detection by error propagation [Data and Source Code]",, heiDATA, V1
The analysis of topographic time series is often based on bitemporal change detection and quantification. For 3D point clouds, acquired using laser scanning or photogrammetry, random and systematic noise has to be separated from the signal of surface change by determining the mini...
