CREATING DIGITAL ELEVATION MODEL USING A MOBILE DEVICE [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017
DEM (Digital Elevation Models) is the best way to interpret topography on the ground. In recent years, lidar technology allows to create more accurate elevation models. However, the problem is this technology is not common all over the world.

Comparative analysis for methods of building digital elevation models from topographic maps using geoinformation technologies

open access: yesGeodesy and Cartography, 2021
The article considers the question of estimating the accuracy of interpolation methods for building digital elevation models using Soviet topographic maps. The territory of the Kursk region of the Russian Federation was used as the study area, because it

A Discrete Geometric Optimal Control Framework for Systems with Symmetries [PDF]

open access: yes, 2007
This paper studies the optimal motion control of mechanical systems through a discrete geometric approach. At the core of our formulation is a discrete Lagrange-d’Alembert- Pontryagin variational principle, from which are derived discrete equations ...

Digital Elevation Model enhancement using Deep Learning [PDF]

open access: yesarXiv, 2021
We demonstrate high fidelity enhancement of planetary digital elevation models (DEMs) using optical images and deep learning with convolutional neural networks. Enhancement can be applied recursively to the limit of available optical data, representing a 90x resolution improvement in global Mars DEMs.
