MVRsimulation recently built a 3D terrain dataset of Latvia, with 0.25 meters per-pixel (mpp) resolution open-source imagery and a digital terrain model compiled at 10m covering the entire country. This terrain was built with the latest version of MVRsimulation Terrain Tools for Esri® ArcGIS®.
The terrain includes cultural features for five areas of interest (AOIs) totalling in 38,913 geotypical building models generated in Esri CityEngine, as well as road networks and powerlines: Keguma (3,771 buildings), Riga (22,276 buildings), Segulda (6,402 buildings), Senite (4,562 buildings), and Zilupe (1,902 buildings). Keguma also features a model of the Kegums hydroelectric power station geolocated on the Daugava River. For nighttime viewing, building models contain emissive light-map textures. The entire terrain is populated with tens of thousands of trees, color-blended to match the underlying imagery.
This Latvia terrain dataset was delivered to the Latvian Ministry of Defence for use in joint terminal attack controller joint terminal attack controller (JTAC) training. The Latvian JTAC training site at the Adazi Military Base uses seven VRSG licenses in its dome-based Advanced JTAC Training System (AJTS). Supported by DefenseTek Solutions, Ltd., these simulation systems enable Latvian JTACs to carry out unit-level continuation, qualification, and mission rehearsal training requirements.
This new Latvia 3D terrain dataset, built with Terrain Tools in MVRsimulation’s round-earth VRSG terrain format, for rendering in VRSG, is available as part of MVRsimulation’s Europe terrain drive to all customers who are on active VRSG software maintenance and are US Government agencies or contractors (for official use only). The Europe terrain dataset is delivered on an external hard drive. (A nominal fee covers the processing of large quantities of data in the VRSG terrain format and the hard drive distribution media.) The Latvia terrain dataset can be viewed only with a valid VRSG version 7.0 or above software license with active software maintenance.
