Digital soil mapping using multiple logistic regression on terrain parameters in southern Brazil Mapeamento digital de solos utilizando regressões logísticas múltiplas e parâmetros do terreno no sul do Brasil

open access: yesScientia Agricola, 2006
Soil surveys are necessary sources of information for land use planning, but they are not always available. This study proposes the use of multiple logistic regressions on the prediction of occurrence of soil types based on reference areas.

An Automated Processing Algorithm for Flat Areas Resulting from DEM Filling and Interpolation

open access: yesISPRS International Journal of Geo-Information, 2017
Correction of digital elevation models (DEMs) for flat areas is a critical process for hydrological analyses and modeling, such as the determination of flow directions and accumulations, and the delineation of drainage networks and sub-basins.

Analysis of flat terrain for the atlas robot [PDF]

open access: yes2013 3rd Joint Conference of AI & Robotics and 5th RoboCup Iran Open International Symposium, 2013
This paper gives a description of an approach to analyze the sensor information of the surroundings to select places where the foot of a humanoid can be placed. This will allow apply such robot in a rescue scenario, as foreseen in the DARPA Robotics Challenge, where a robot is forced to traverse difficult terrain.

TERRAIN TECTONICS OF THE CENTRAL ASIAN FOLDED BELT

open access: yesГеодинамика и тектонофизика, 2015
The terrain analysis concept envisages primarily a possibility of approximation of fragments / terrains of various geodynamic settings which belong to different plates. The terrain analysis can supplement the theory of plate tectonics in solving problems

Distributed texture-based terrain synthesis [PDF]

open access: yes, 2011
Terrain synthesis is an important field of Computer Graphics that deals with the generation of 3D landscape models for use in virtual environments. The field has evolved to a stage where large and even infinite landscapes can be generated in realtime ...

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).
