Operationalizing the spatial influence of the risk factors behind the open-air drug markets in Durham region
… The results are based on the use of the Risk Terrain Modeling (RTM) to explore tile spatial factors behind the open-air drug markets. In particular, the spatial influences of the criminogenic features, which are alcohol outlets, bus stops, street robbery, and prostitution areas on open-air …

A study of the relationship between the use of GIS and project success in selected construction organizations
… as related to the following two GIS functions: Terrain Modeling and Traffic Management. Some functions that were very close to the .05 level of significance included Estimating Project Costs, Terrain Analysis, 2D and 3D Visualization, and Route/Site Selection.</p> <p>Recommendations included the …

An Analysis and Critique of DEM Creaion and 3-D Modeling Using Airborne LIDAR and Photogrammetric Techniques
… projects. Accurate digital representations of terrain and ground features are extremely useful for efficient design, communication and data representation in projects involving land development, transportation planning, hydrologic analysis, environmental impact studies, and much more. Within …

3-D Point Cloud Generation from Rigid and Flexible Stereo Vision Systems
… become a concern. Deciding if an area of terrain has a level enough slope and a wide enough area to land a Vertical Take Off and Landing (VTOL) UAV or if an area of terrain is traversable by a ground robot is reliant on data gathered from sensors, such as cameras. 3-D models, which can be …

Prime Number-Based Hierarchical Data Labeling Scheme for Relational Databases
… computer science fields including data mining, terrain modeling, and image analysis. A good representation of such data accurately captures the parent-child and ancestor-descendent relationships between nodes. There exist a number of different ways to capture and manage hierarchical data while …

Design and Implementation of Articulated Robotic Tails to Augment the Performance of Reduced Degree-of-Freedom Legged Robots
… support polygon on both flat and uneven terrain. Modeling of the combined legged robotic systems and attached articulated tails has led to the derivation of dynamic formulations that were analyzed to scale articulated tails onboard legged robots to maximize inertial adjustment …

Stochastic Terrain and Soil Modeling for Off-Road Mobility Studies
… representations of the variability of the terrain profile. It is not practically feasible to measure the terrain at a sufficiently large number of points, or, if measured, to use such data directly in the simulation. Dedicated modeling techniques and computational methods that realistically …

Refining and Expanding the Feature Stamping Process
… processes depends largely on how well the input terrain data represents the earth's surface. Modelers obtain terrain data for a study area by performing surveys or by gathering historical survey data. If a modeler desires to create a predictive model to simulate the addition of man-made features …
