Terrain Analysis for Armed Forces

CARTOCON, 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 Analysis Enhancements to the Height Above Nearest Drainage Flood Inundation Mapping Method

Water Resources Research, 2019
Flood inundation remains challenging to map, model, and forecast because it requires detailed representations of hydrologic and hydraulic processes.

Traversability Analysis by Semantic Terrain Segmentation for Mobile Robots

2021 IEEE 17th International Conference on Automation Science and Engineering (CASE), 2021
Mobile robots have the potential to be used in many outdoor tasks, such as search and rescue, patrolling, and delivery services. To enable robots to safely navigate through outdoor environments, it is important to analyse the terrain.

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.

Lunar Crater Detection Based on Terrain Analysis and Mathematical Morphology Methods Using Digital Elevation Models

IEEE Transactions on Geoscience and Remote Sensing, 2018
Lunar impact craters are the most typical geomorphic feature on the moon and are of great importance in studies of lunar terrain features. This paper presents a crater detection algorithm (CDA) that is based on terrain analysis and mathematical ...

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

Incremental terrain visibility analysis

SPIE Proceedings, 2006
Visibility analysis is an important aspect in terrain analysis. Terrain visibility calculation is a time-consuming process, and visibility algorithms are dedicated to reduce the algorithm complexity to enhance calculation speed. We use digital elevation model to represent terrain.
