SHAPE MODELING AND ANALYSIS OF TERRAIN

International Journal of Shape Modeling, 1994
Summary: The construction of high-fidelity digital terrain models (DTM) requires the development of adaptive techniques for modeling and analysis of terrain surfaces. The paper presents a conceptual framework for digital terrain modeling which includes all relevant tasks to achieve this goal.

Multi-scale terrain representation and terrain analysis

SPIE Proceedings, 2009
Multi-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

2014
The 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.

Terrain matching by analysis of aerial images

[1990] Proceedings Third International Conference on Computer Vision, 2002
A 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.

Terrain analysis and remote sensing

Photogrammetria, 1982
Remote sensing has been used in terrain analysis for several decades in the form of conventional black and white aerial photographs. During the past decade or so, newer forms of remote sensing and improved methods of data analysis have become widely available. A number of texts now exist outlining the principles of remote sensing and their applications

Efficient representation and analysis of triangulated terrains

Proceedings of the 25th ACM SIGSPATIAL International Conference on Advances in Geographic Information Systems, 2017
Terrain 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, 1962
Area 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.

Uncertainty analysis for soil‐terrain models

International Journal of Geographical Information Science, 2006
The 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.

Analysis of terrain using multispectral images

Pattern Recognition, 1997
Automated 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.

Software for Modelling and Analysis of Rover on Terrain

Proceedings of Conference on Advances In Robotics, 2013
Wheeled 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 ...
