Shaping pre-modern digital terrain models: The former topography at Charlemagne's canal construction site. [PDF]
PLoS ONE, 2018 The use of remote sensing techniques to identify (geo)archaeological features is wide spread. For archaeological prospection and geomorphological mapping, Digital Terrain Models (DTMs) on based LiDAR (Light Detection And Ranging) are mainly used to ...

Development of a stream DTM generation methodology using UAV-based SfM and LiDAR point cloud. [PDF]
Sci RepFiltering ground points and generating accurate Digital Terrain Models (DTMs) are crucial for hydrological and ecological modeling in riverine environments. This paper proposes a methodology for DTM generation in stream areas by integrating point clouds from a UAV-based structure from motion (SfM) and light detection and ranging (LiDAR) while applying ...

METHODS FOR THE UPDATE AND VERIFICATION OF FOREST SURFACE MODEL [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016 The digital terrain model (DTM) represents the bare ground earth's surface without any objects like vegetation and buildings. In contrast to a DTM, Digital surface model (DSM) represents the earth's surface including all objects on it.

A SEGMENT-BASED APPROACH FOR DTM DERIVATION OF AIRBORNE LIDAR DATA [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016 Abstract. With the characteristics of LIDAR system, raw point clouds represent both terrain and non-terrain surface. In order to generate DTM, the paper introduces one improved filtering method based on the segment-based algorithms. The method generates segments by clustering points based on surface fitting and uses topological and geometric properties

Airborne laser scanning for terrain modeling in the Amazon forest [PDF]
Acta Amazonica, 2018 Very few studies have been devoted to understanding the digital terrain model (DTM) creation for Amazon forests. DTM has a special and important role when airborne laser scanning is used to estimate vegetation biomass.
