Terrain visual databases are accurate and interactive representations of real geographic areas. Each visual database is designed and built to perfectly fit the type of application it is used in. Terrain size, resolution, and detail level are perfectly balanced with performance in order to provide a realistic and immersive experience for trainees and system operators.
At the core of a terrain visual database are two main geoelements:
1. A digital terrain model (DTM), which represents the topographic bed on which the virtual visual
database is laid
2. Aerial imagery, which is the visual layer that is laid on top of the DTM
Put together, the two geoelements create an interactive 3D terrain. On top of that newly created environment, we insert and populate 3D models of both natural components, such as vegetation, and man-made components such as buildings and roads to provide a realistic and immersive experience for trainees and system operators.
Ultra High Resolution OFF-ROAD for Training at Ground Level
Ground-level visual databases are the most complex visual databases to create and render. Due to a trainee’s low point of view and the fact that the entire training session occurs on the ground, overall visual quality must be ultrahigh, even up to 3 to 5 centimeters per pixel. Ground-level visual databases are therefore created with ultrahigh-resolution data: imagery, topography, vector data, textures, and 3D models and artifacts.
Extensive Far Reaching Areas,
Exceptional Airports Modeling
Flight simulation visual databases are usually created using medium-low-resolution source geodata such as orthophotos and digital terrain models. They cover extremely large geographic areas that may include full countries and even continents. Every visual database is created to fit the specific needs of such end users as jet fighter pilots, commercial airplane pilots, helicopter pilots, and umanned-aerial-vehicle operators. Because every flight starts and ends in an airport, airport modeling receives special attention. Airport modeling is created at different modeling levels—from geotypical to accurate geospecific level D models. Our airports include professional runway and taxiway lighting systems, ground markings, and signages. All are fully compatible with FAA standards. For more details

High-Resolution Surface Representation
3D visual databases for mining simulation are highly detailed ground-level terrains that are created using an ultrahigh digital terrain model grid. The unique topographical structure of open-pit mines is built of angled and stepped sides, which requires highly detailed surface textures of few centimeters per pixel in order to provide high visual quality. The mining industry uses simulators to train truck drivers and heavy-machinery operators for improvement in technical operation for promotion of safety. These visual databases are very complex with regard to terrain detail, textures, and 3D artifacts.
