Terrain [PDF]

open access: yesBorderlands journal, 2021
Abstract Indigenous leaders and scholars demand greater respect for their governance and knowledge authority, with one priority the de/centring of the environmental management research-praxis arising out of natural science traditions (Latulippe and Klenk, 2020).

Curvature Weighted Decimation: A Novel, Curvature-Based Approach to Improved Lidar Point Decimation of Terrain Surfaces

open access: yesGeomatics, 2023
Increased availability of QL1/QL2 Lidar terrain data has resulted in large datasets, often including large quantities of redundant points. Because of these large memory requirements, practitioners often use decimation to reduce the number of points used ...

Characteristics of Ozone Pollution in Tai’an and Topographic Effects of Mount Tai

open access: yesAtmosphere, 2022
Through the analyses of the observed concentrations of ozone (O3) in Tai’an from 2016 to 2021, the results show that O3 pollution was relatively serious, with the mean concentrations of the 90th percentile of daily maximum 8-h O3 (O3-8h-90per) above 180 ...

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.

Fast approximation of visibility dominance using topographic features as targets and the associated uncertainty [PDF]

open access: yes, 2003
An approach to reduce visibility index computation time andmeasure the associated uncertainty in terrain visibility analysesis presented. It is demonstrated that the visibility indexcomputation time in mountainous terrain can be reduced substantially ...

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 ...

Geo-environmental mapping using physiographic analysis: constraints on the evaluation of land instability and groundwater pollution hazards in the Metropolitan District of Campinas, Brazil [PDF]

open access: yes, 2010
Geo-environmental terrain assessments and territorial zoning are useful tools for the formulation and implementation of environmental management instruments (including policy-making, planning, and enforcement of statutory regulations).

Terrain classification for a quadruped robot [PDF]

open access: yes, 2013
Using data retrieved from the Puppy II robot at the University of Zurich (UZH), we show that machine learning techniques with non-linearities and fading memory are effective for terrain classification, both supervised and unsupervised, even with a ...

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).

Vague terrain, terrain vague ? [PDF]

open access: yesArcheopages, 2017
à partir d’un espace « vide », un « terrain vague », reconnu au cœur du vicus gallo-romain de Diodurum (Yvelines), émerge une série de questions quant à sa nature, sa fonction, son statut. C’est aussi, plus généralement, celles de son rapport à la ville, à son espace, à sa structure même, composée de « pleins » mais aussi de « vides », qui sont posées ...
