digital elevation models

Study of digital elevation models of objects of historical and cultural heritage created over different years

The purpose of the work is to investigate the digital elevation models of the mass grave of 1944, built on the basis of aerial and cartographic data of different times. The implementation of the task involves the construction of digital elevation models (DEM) on the territory of the Jewish mass grave in the city of Vynnyky and Italian prisoners of war near the city. On the territory of the Jewish mass grave in the city of Vynnyky, a DEM was created based on a stereo pair of archival aerial images obtained in 1944 and on the basis of aerial photography from a UAV conducted in 2015.

Methodology for automatic extraction of structural relief lines from raster DEMs created by laser scanning data

It is proposed for automatical detecting of break-lines from raster Digital Terrain Models (DTM) based on geo-informational modeling. Practical implementation is performed on the DTM, was been created from Laser Scanning.


Analysis of the results of the use UAV Trimble UX-5 for creation of orthophotomaps and digital model of relief

Purpose. The purpose of this paper is to analysis and research capabilities of unmanned aerial vehicle (UAV) Trimble UX5 to create orthophotomap and digital elevation models (DEM), as well as identifying and addressing possible shortcomings in the aerial survey and processing of aerial photographs. Methods. Before starting aerosurveying conducted reconnaissance of the area.
