A Method of Optimizing Terrain Rendering Using Digital Terrain Analysis [PDF]
ISPRS International Journal of Geo-Information, 2021 Terrain rendering is an important issue in Geographic Information Systems and other fields. During large-scale, real-time terrain rendering, complex terrain structure and an increasing amount of data decrease the smoothness of terrain rendering. Existing rendering methods rarely use the features of terrain to optimize terrain rendering.

Flood Risk Analysis on Terrains [PDF]
Proceedings of the 25th ACM SIGSPATIAL International Conference on Advances in Geographic Information Systems, 2017 An important problem in terrain analysis is modeling how water flows across a terrain and creates floods by filling up depressions. In this article, we study the flooding query problem: Preprocess a given terrain Σ, represented as a triangulated xy -monotone surface with n

Analysis of terrain navigability in underwater terrain aided navigation [PDF]
Journal of Physics: Conference Series, 2021 Abstract Aiming at the problem that the single terrain characteristic parameter cannot comprehensively evaluate the terrain navigability of the matching areas, the weighted vector correlation degree is introduced, and the terrain characteristic parameters such as the standard deviation of terrain elevation, roughness, correlation ...

Ontological analysis of terrain data [PDF]
Proceedings of the 2nd International Conference on Computing for Geospatial Research & Applications - COM.Geo '11, 2011 Geographic applications require increasingly accurate data, for example to support high fidelity visual simulations. However, information about data accuracy is typically not directly available, and must instead be inferred from the manner in which the data was acquired and processed.

Orometry-based terrain analysis and synthesis [PDF]
ACM Transactions on Graphics, 2019 Mountainous digital terrains are an important element of many virtual environments and find application in games, film, simulation and training. Unfortunately, while existing synthesis methods produce locally plausible results they often fail to respect global structure.

Quantitative and Qualitative Terrain Analysis Based on Digital Terrain Model
IOP Conference Series: Earth and Environmental Science, 2021 Abstract Within the Digital Terrain Models (DTM) processing and consequently qualitative and quantitative analysis, it is possible to gain a credible imagination of real terrain shape. In order to obtain an appropriate DTM, it is necessary to decrease the influence of the gross errors that have negative effects on the final DTM.

Analysis of flat terrain for the atlas robot [PDF]
2013 3rd Joint Conference of AI & Robotics and 5th RoboCup Iran Open International Symposium, 2013 This paper gives a description of an approach to analyze the sensor information of the surroundings to select places where the foot of a humanoid can be placed. This will allow apply such robot in a rescue scenario, as foreseen in the DARPA Robotics Challenge, where a robot is forced to traverse difficult terrain.
