Accuracy assessment of ALOS AW3D30 DSM and comparison to ALOS PRISM DSM created with classical photogrammetric techniques

European Journal of Remote Sensing, 2020
In this study the accuracy of ALOS Global Digital Surface Model (AW3D30) with a point spacing of approx. 30-meter mesh was examined, taking as a case study several areas of Greece with complex geomorphologic characteristics.

High resolution digital surface model (DSM) to support modelling of urban flooding. [PDF]

, 2011
This research work focuses on the generation of a high resolution digital surface model featuring complex urban surface characteristics in order to enrich the database for runoff simulations of urban drainage systems. The discussion of global climate change and its possible consequences have taken centre stage over the last decade.

Evaluation of Footprint Horizontal Geolocation Accuracy of Spaceborne Full-Waveform LiDAR Based on Digital Surface Model

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
Spaceborne full-waveform LiDAR has shown unique advantages in measuring global surface elevation. Laser footprints generally have decimeter-level vertical accuracy, meeting the requirement of ground elevation control points.

Enhancing Photogrammetric DSM Based on Multiscale and Domain-Invariant Semantic Feature Learning

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Despite the rapid development of stereo matching techniques, digital surface models (DSMs) reconstructed from disparities suffer from occlusion, solar shadow, and textureless ambiguity, thus failing to meet the requirements of 3-D city modeling.

Detecting changes between a DSM and a high resolution SAR image with the support of simulation based separation of urban scenes [PDF]

, 2012
As a SAR image is often the only available data in crisis situations, e.g. after an earthquake, a change analysis of the SAR image with previously acquired data may enable a fast analysis of the damage caused by the disas-ter.
