Although a number of terrain generation techniques have been proposed during the last few years, all of them have some key constraints. Modelling techniques depend highly upon designer's skills, time, and effort to obtain acceptable results, and cannot be used to automatically generate terrains. The simpler methods allow only a narrow variety of terrain types and offer little control on the outcome terrain. The Genetic Terrain Programming technique, based on evolutionary design with Genetic Programming, allows designers to evolve terrains according to their aesthetic feelings or desired featur

This paper summarizes typical energy-balance data for a variety of polar terrain types, to aid in a better understanding of climate and climate change. Terrain types examined include closed boreal forests, open woodlands, tundra, the pack ice of the Arctic Ocean, glaciers and large ice sheets. For each of these terrains energy-balance-related parameters, including albedo, surface roughness, and thermal diffusivity of the subsurface and their seasonal variations are considered. Components of the surface energy balance, and particularly the net radiation or radiation balance, are presented on a

We present a robust control scheme for skid-steered vehicles that enables high-speed path following on challenging terrains. First, a kinematic model with experimentally identified parameters is constructed to describe the terrain-dependent motion of skid-steered vehicles. Using Lyapunov theory, a nonlinear control law is defined, guaranteeing the convergence of the vehicle to the path. To allow smooth and accurate motion at higher speeds, an additional linear velocity control scheme is proposed, which takes actuator saturation, path following error, and reachable curvatures into account.

Identifying terrain parameters is important for high-fidelity simulation and high-performance control of planetary rovers. The wheel–terrain interaction classes (WTICs) are usually different for rovers traversing various types of terrain. Every terramechanics model corresponds to its wheel–terrain interaction class (WTIC). Therefore, for terrain parameter identification of the terramechanics model when rovers traverse various terrains, terramechanics model switching corresponding to the WTIC needs to be solved. This paper proposes a speed-independent vibration-based method for WTIC recognition

This paper presents the method for a vision-based terrain recognition system that uses a convolutional neural network (CNN). The dataset includes images of various terrains under different conditions. The pretrained CNN is used for extracting features from pre-processed images, which are then used to classify the terrain types. The SoftMax layer of the architecture provides the result of terrain recognition. In the present work, experiments are performed with two pre-trained models. The system provides 80% accuracy using Tensorflow and ensemble learning Keywords— CNN; ; Tensorflow; terrain rec

The hazard of ice accretion on overhead power circuits is significant, yet predicting it is very difficult. The key reason lies in the shortage of sufficient observational data on ice thickness, and previous studies have also rarely taken into account micro-terrain and micro-meteorological conditions. In response to the challenge of simulating overhead line icing, this study introduces a new icing simulation technique that fully considers the effects of micro-terrain and micro-meteorology. For this technique, typical micro-terrains of overhead line areas are first identified by using high-reso

The similarities and differences in the mechanical characteristics of the cylinders in the environments with and without terrains are compared. The research results show that, when the IWs propagate over terrain, the waveform structures are prone to continuous changes. The intense reverse alte

Flygburen laserskanning är en effektiv metod för insamling av höjddata över stora områden och används därför frekvent som underlag till digitala höjdmodeller, både på nationell och regional nivå (Wehr & Lohr 1999). Fördelen med insamlingsmetoden är att de utsända laserpulserna reflekteras på både markytan och objekten ovan mark, exempelvis vegetation, byggnader och liknande. På så vis genereras ett tredimensionellt punktmoln från vilket ytterligare produkter kan genereras.

The article describes the forms and methods of analyzing complex terrain in design. The impact of complex terrain analysis on the design and construction process. The tasks of terrain analysis and the sequence of its study are considered, morphometric methods of terrain analysis, their features, tools and sequence of actions are presented. Examples of the application of the above methods of analysis are considered on the example of the coastal zone of the Voronezh reservoir.

Simplified Finite Element Analysis (FEA) truck tire models are developed and used to examine the interaction between the tire and various types of terrain. Soft terrain such as hard soil and dry sand is modeled using solid, elastic-plastic elements. The general trends of vertical and longitudinal forces and normal and shear stress distributions in the soft soil are compared with published data for preliminary validation. The cornering characteristics on both rigid and soft soil terrains are also predicted and compared. Additionally, a detailed FEA truck tire is introduced as the next phase of

The U.S. Army is increasingly interested in autonomous vehicle operations, including off-road autonomous ground maneuver. Unlike on-road, off-road terrain can vary drastically, especially with the effects of seasonality. As such, vehicles operating in off-road environments need to be in-formed about the changing terrain prior to departure or en route for successful maneuver to the mission end point. The purpose of this report is to assess machine learning algorithms used on various remotely sensed datasets to see which combinations are useful for identifying different terrain. The study collec

Thaw of permafrost and associated ground ice melt can reduce ground stability, modify terrain, and reconfigure drainage patterns affecting terrestrial and aquatic ecosystems and presenting challenges to northern infrastructure and societies. The integrity of ground-based transportation infrastructure is critical to northern communities. Geomorphic features can indicate ground ice presence and thaw susceptibility.

Autonomous ground vehicle (AGV) research for military applications is important for developing ways to remove soldiers from harm’s way. Current AGV research tends toward operations in warm climates and this leaves the vehicle at risk of failing in cold climates. To ensure AGVs can fulfill a military vehicle’s role of being able to operate on- or off-road in all conditions, consideration needs to be given to terrain of all types to inform the on-board machine learning algorithms. This research aims to correlate real-time vehicle performance data with snow and ice surfaces derived from multispec

The Natural Sounds and Night Skies Division (NSNSD) received a request to collect baseline acoustical data on Great Smoky Mountains National Park (GRSM) roadways. Two acoustic monitoring stations were deployed during the summer (June/July) and winter (November/December) of 2023. The goal of the study was to conduct an acoustic inventory at these locations and to understand the degree to which vehicle noise in general, and specifically utility terrain vehicle (UTV) noise, may affect wildlife and visitor experience. In recent years, there has been an increase in the use of Utility Terrain Vehicl

Permafrost conditions in the Slave Geological province are not well understood. Thaw of permafrost and associated ground ice can reduce ground stability, which modifies terrain and drainage patterns and affects terrestrial and aquatic ecosystems. This presents critical challenges to northern resource development and societies where thaw of ice-rich permafrost negatively affects the integrity of ground-based infrastructure. In an effort to address this knowledge gap, this report presents a digital georeferenced database of landforms identified in permafrost terrain using high-resolution satelli
