Evaluating Suitable Analysis Methods Using Digital Terrain in Viewshed Analysis [PDF]
Journal of the Korean Association of Geographic Information Studies, 2011 The purpose of this study is to contribute enhancing the accuracy of viewshed analysis through the explanation for an analysis method of viewshed analysis using GIS. According to previous studies, the visible area using digital terrain in viewshed analysis depends on a visible interest area, scale of terrain, spatial resolution and surface data.

Uncertainty Analysis of Digital Elevation Models by Spatial Inference From Stable Terrain
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022 The monitoring of Earth’s and planetary surface elevations at larger and finer scales is rapidly progressing through the increasing availability and resolution of digital elevation models (DEMs). Surface elevation observations are being used across an expanding range of fields to study topographical attributes and their changes over time, notably in ...

Grip and Grasp: Lizard Claw Inspired Robotic Manipulators
Advanced Robotics Research, EarlyView.Our study identifies the most effective lizard claw shape for use as an end effector in a bioinspired robotic manipulator. By examining key geometric features and combining them into comparative indices, the Crotaphytus collaris claw is found to be the best fit.

The estimation of errors in calculated terrain corrections in the Tatra Mountains
Contributions to Geophysics and Geodesy, 2010 In general, calculation of terrain corrections can be a substantial source of errors in evaluating Bouguer anomalies, especially in rugged mountainous areas like the Tatra Mountains where we also get the largest values of the terrain corrections as such.

A theoretical approach to domain decomposition for parallelization of Digital Terrain Analysis
Annals of GIS, 2013 Nowadays, many geocomputations are benefiting from parallel computing technologies. As a category of data and computationally intensive problems, Digital Terrain Analysis (DTA) can be improved by parallelization based on data parallelism. Load-balancing is one of the factors impacting the performance of a parallel DTA algorithm.

Systematic Exploration of 3D Concrete Printing Parameters for Conformal Printing on Sloped Surfaces
Advanced Robotics Research, EarlyView.A conformal slicing algorithm is developed for robotic 3D concrete printing (3DCP) on sloped surfaces as a first step toward printing slab‐on‐grade foundations on uneven terrain. Systematic experiments quantify the effects of nozzle speed, extrusion rate, and toolpath direction on filament dimension and stability.
