Assessing Vertical Accuracy and Spatial Coverage of ICESat-2 and GEDI Spaceborne Lidar for Creating Global Terrain Models

Digital Elevation Models (DEMs) are a necessity for modelling many large-scale environmental processes. In this study, we investigate the potential of data from two spaceborne lidar altimetry missions, ICESat-2 and GEDI—with respect to their vertical accuracies and planimetric data collection patterns—as sources for rasterisation towards...

Computational modelling of terrains

The book Computational modelling of terrains presents an overview of algorithms and methodologies to reconstruct, manipulate, and extract information from terrains.<br/><br/>It covers different representations of terrains (eg TINs, rasters, point clouds, contour lines) and presents techniques to handle large datasets.

Icesat full waveform altimetry compared to airborne laser altimetry over the Netherlands

Since 2003 the spaceborne laser altimetry system on board of NASA’s Ice, Cloud and land Elevation Satellite (ICESat) has acquired a large world-wide database of full waveform data organized in 15 products. In this research three products are evaluated over The Netherlands. For this purpose the raw full waveform product, the derived Gaussian...
