Automated Conflation of Digital Elevation Model with Reference Hydrographic Lines
ISPRS International Journal of Geo-Information, 2020 Combining misaligned spatial data from different sources complicates spatial analysis and creation of maps. Conflation is a process that solves the misalignment problem through spatial adjustment or attribute transfer between similar features in two ...

Flood Risk Analysis on Terrains [PDF]
Proceedings of the 25th ACM SIGSPATIAL International Conference on Advances in Geographic Information Systems, 2017 An important problem in terrain analysis is modeling how water flows across a terrain and creates floods by filling up depressions. In this article, we study the flooding query problem: Preprocess a given terrain Σ, represented as a triangulated xy -monotone surface with n
