Multi-scale terrain representation and terrain analysis
SPIE Proceedings, 2009Multi-scale handling and representation of terrain is one of the key hot topics in GIS. It can meet the demand of different users on the different scale geo-spatial data. Through multi-scale representation of terrain the non-scale GIS can be achieved and the users can acquire the info they care about easily by such GIS.

Terrain Analysis for Armed Forces
2014The main activities of armed forces take place in the terrain. Knowledge of terrain impact on such activities is very substantial for their achievement. Terrain impact on chosen activities can be described using mathematical models and these can be applied in GIS.

Efficient representation and analysis of triangulated terrains
Proceedings of the 25th ACM SIGSPATIAL International Conference on Advances in Geographic Information Systems, 2017Terrain trees are a new in-core family of spatial indexes for the representation and analysis of Triangulated Irregular Networks (TINs). Terrain trees combine a minimal encoding of the connectivity of the underlying triangle mesh with a hierarchical spatial index, implicitly representing the topological relations among vertices, edges and triangles ...

Area Sampling for Terrain Analysis
The Professional Geographer, 1962Area sampling is most useful in reducing the time and effort required for studies of large areas. It permits the formulation of rapid approximations and, because time is saved, it enables more detailed observations to be made and a greater number of variables to be considered.

Analysis of terrain using multispectral images
Pattern Recognition, 1997Automated terrain analysis is required for many practical applications, such as outdoor navigation, image exploitation, remote sensing, reconnaissance and surveillance. In this paper, we present a hierarchical approach to analyze multispectral (MS) imagery for autonomous land vehicle navigation.

Terrain matching by analysis of aerial images
[1990] Proceedings Third International Conference on Computer Vision, 2002A terrain matching algorithm has been developed for use in a passive aircraft navigation system. A sequence of aerial, optical images is matched to a reference digital map of the three-dimensional terrain. Stereo analysis of successive images results in the recovery of an elevation map of the observed terrain.

Software for Modelling and Analysis of Rover on Terrain
Proceedings of Conference on Advances In Robotics, 2013Wheeled rovers traversing soft terrain are subjected to extensive testing to determine the slope climbing limits, obstacle limits, steering limits and drive torque/power requirements. To understand the wheel soil interaction and reduce the number of tests, simulation software enabling virtual runs of the rover on soft soil have been developed by Space ...

Terrain analysis from curvature profiles
International Journal of Imaging Systems and Technology, 1990AbstractThis paper describes a new algorithm which uses Gaussian and mean curvature values of the terrain surface to extract feature points. These points are then used for recognition of particular subregions of the terrain and in estimating relative positions of these subregions in the terrain.

Uncertainty analysis for soil‐terrain models
International Journal of Geographical Information Science, 2006The aim of the study was to examine how robust soil‐terrain models are to uncertainty in the source elevation data. The study site was a 74 ha agricultural field in Australia. A global positioning system was used to measure elevation and the uncertainty of the measurement, therefore allowing maps of elevation and its uncertainty to be created.

Performance analysis and terrain classification for a legged robot over rough terrain
2012 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2012Minimally actuated millirobotic crawlers navigate unreliably over uneven terrain-even when designed with inherent stability-mostly because of manufacturing variabilities and a lack of good models for ground interaction. In this paper, we investigate the performance of a legged robot as it traverses three distinct rough terrains: tile, carpet, and ...
