Accumulated Surfaces & Least-Cost Paths: GIS Modeling for Autonomous Ground Vehicle (AGV) Navigation
… an accumulated surfaces can be built on which a least-cost path can be located. The sensitivity analysis allows generation of many routes which can be field tested for the appropriate weight selection for each factor. Ultimately, the entire process would select an optimal path and output closely …

Identification of barriers and least cost paths for autonomous vehicle navigation using airborne LIDAR data
… a significant role in identifying barriers and least cost paths for such vehicles. Least cost paths minimize the sum of impedance across a surface. Impedance can be measured by steepness of slope, impenetrable barriers such as vegetation and buildings, fence lines and streams, or other factors …

Autonomous Vehicle Path Planning with Remote Sensing Data
… problem. Previous research has demonstrated that least cost paths generated from aerial LIDAR and GIS data could play a role in automatically determining suitable routes over otherwise unknown terrain. However, most of this research has been theoretical. Consequently, there is very little …

The networked polis: Unravelling Magnesia's place in the Hellenistic world through the digital reconstruction of journeys.
… topographic dataset. A minimum total cost methodology is used to construct a network of least cost paths linking 2,600 nodes across the Greek world, calibrated with the Peutinger Table and Delphic theorodokoi list. The network is applied to solving the travelling salesman problem under …

DISPERSAL BEHAVIOR OF WHITE-TAILED DEER IN AN AGRICULTURAL LANDSCAPE
… to record dispersal and excursion movement paths. Linear mixed effects models were used to test for differences in path characteristics between sexes and ages (e.g., distance, straightness, duration, and speed). I used known-fate models, with demographic, temporal, and home range variables …

The Archaeology of Travel in Greater Nicoya (500 BC – AD 1250)
… hamlets in western Nicaragua and northwestern Costa Rica. Traveling across land and canoeing or rafting over the large freshwater lakes and rivers, these peoples voyaged for many hours to trade goods and maintain social and political ties with their neighbors. The range and frequency of these …
