MUMBAI, India, November 27, 2013 /PRNewswire/ -- Rolta today announced that it has been awarded a prestigious 3D City Modeling contract by a major Middle-East country. Valued at over $25M, this is one of the largest and most comprehensive projects of its kind ever undertaken. (Logo: http://photos.prnewswire.com/prnh/20121023/570667 ) Rolta is an early mover in adopting and mastering the technologies required to address this emerging trend of using 3D City Models for municipal management. The Company first won a project for establishing a large 3D map for Dubai. With subsequent multi-million dollar add-on awards from Dubai, and one recently from the Sultanate of Oman, Rolta has developed specialized software tools and has established an enviable track-record for creating intelligent 3D Maps. This is an ambitious project designed to fulfill the challenges of sophisticated analysis and simulation for town planning, infrastructure development, environmental management, homeland security and emergency response. The project entails creation of a 3D model of various municipal areas covering nearly 5000 sq km, with tens of thousands of buildings. The model would be a lot more than a composite picture of the region -- it shall be architected to build intelligence into the model for each building, feature, roadway and parcel through dynamic linkages to disparate data sources. Exterior surfaces of buildings will be rendered in a photo-realistic manner and a user could "fly" through the model to visualize areas of interest. Interiors of thousands of buildings and many prominent landmarks will also be modeled in 3D to high levels of accuracy. Modeling a city in 3D involves deployment of very sophisticated technologies, such as aerial oblique imaging, photogrammetric mapping, street-view imaging, GPS surveys, laser-scanning, and integration of numerous data sources into a CityGML data warehouse that can be accessed via the Web by diverse users based on security access privileges of each. Rolta will use a number of software suites from its large repository of intellectual property to perform various tasks.
