Breeding Terrains with Genetic Terrain Programming: The Evolution of Terrain Generators [PDF]

open access: yesInternational Journal of Computer Games Technology, 2009
Although a number of terrain generation techniques have been proposed during the last few years, all of them have some key constraints. Modelling techniques depend highly upon designer′s skills, time, and effort to obtain acceptable results, and cannot be used to automatically generate terrains.

On realistic terrains

open access: yesProceedings of the twenty-second annual symposium on Computational geometry, 2006
This paper is focused on the worst-case complexities of the visibility map and the shortest paths on realistic polyhedral terrains. The authors give a set of input assumptions which can reasonably present the values of the model parameters in terrains that arise in practice.

Spatial patterns of surface soil moisture and hydro-physical properties in Lijiang River watershed

open access: yesShui kexue jinzhan, 2016
Spatial heterogeneity is a basic characteristic of soil moisture and hydro-physical properties. We applied geostatistical approach to assess the spatial patterns of soil moisture and hydro-physical properties to identify the distribution and variability ...

Multifractal Correlation between Terrain and River Network Structure in the Yellow River Basin, China

open access: yesISPRS International Journal of Geo-Information, 2022
As the most basic physical geographic elements, basin terrain and river networks have high spatial complexity and are closely related. However, there is little research on the correlation between terrain and river networks.

A cellular-automata model for assessing the sensitivity of the street network to natural terrain

open access: yesAnnals of GIS, 2021
Natural  and human-made features are not exclusive in settlements but interact across time and space, placing the context in constant evolution. The purpose of this paper is to search for the influence of terrain, a natural feature, on the configuration ...

Numerical Study of the Impact of Complex Terrain and Soil Moisture on Convective Initiation

open access: yesAtmosphere, 2020
The relative importance of topography and soil moisture on the initiation of an afternoon deep convection under weak synoptic-scale forcing was investigated using the weather research and forecasting (WRF) model with high resolution (1.33 km).

A survey on terrain based navigation for AUVs [PDF]

open access: yes, 2010
Terrain Based Navigation (TBN) is a method rootedto the early cruise missile navigation systems, when GPS wasnot yet available. For decades, TBN has been applied as acomplementary system to INS navigation for Unmanned AerialVehicles (UAV).
