Experimental results of a terrain relative navigation algorithm using a simulated lunar scenario [PDF]
, 2015 This paper deals with the problem of the navigation of a lunar lander based on the Terrain Relative Navigation approach. An algorithm is developed and tested on a scaled simulated lunar scenario, over which a tri-axial moving frame has been built to ...

DEVELOPMENT OF A DIGITAL ELEVATION MODEL OF KARA-BOGAZ-GOL BAY
Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2020 The article presents the results of the efforts to create a digital elevation model of Kara-Bogaz-Gol Bay. The informational background for the digital elevation model was maps of 1:200 000 and 1:100 000 scales. The digital elevation model was created by

Comparative analysis of the differences between using LiDAR and contour-based DEMs for hydrological modeling of runoff generating debris flows in the Dolomites [PDF]
, 2015 Present work aims to explore the differences in hydrological modeling when using digital elevation models (DEMs) generated by points from LiDAR surveys and those digitized on the contour lines of the regional technical map (RTM) and their relevance for ...
