3D GIS in China | GIM International

Not only For VisualisationUser BenefitsE-CommerceBIMThe Chongqing 3D models are highly informative models; one can take coordinates from the 3D objects, other attributes and hyperlinks for further information, etc. Therefore the 3D models with different levels of detail – from topographic sources to civil & infrastructure engineering and AEC – are not only for visualisation purposes, but are also widely used in environmental simulation and decision-making. They facilitate many changes. For instance, the rule-based 3D engine provides real-time adjustment, 3D simulation and assessment for the planning and design schemes. These are new but very effective technological tools for the workflow planners, according to Ms Xue: “The 3D engine can also be applied in ‘intensive’ city management when connected with information about enterprises, population and real estate.” CSI maintains a leading position at national level in the aspects of key 3D city simulation and 3D modelling technologies, mass multi-source data integration, and so on.

An Alliance PartnershipModern GIS AdvantagesReplacement SuccessAbout ITC Holdings Corp.Implementing a business strategy, ITC Holdings Corp. — including its subdivision ITCTransmission— entered into an alliance partnership with Mitsubishi Electric Power Products Inc. (MEPPI; Warrendale, Pennsylvania). Although there is nothing revolutionary about the companytight manufacturing tolerances, simple proven designs and attention to detail during assembly (especially with single O-ring seals and sealant products), MEPPI has developed a reputation for high-quality products with the lowest overall cost of ownership. Choosing to partner with MEPPI made sense to ITC for a variety of reasons. An important design feature required for new circuit breakers was that the mechanisms driving the interrupters not rely on pneumatic or hydraulic pressure. ITCpast experience with the inherited air-blast and hydraulically driven circuit breakers was that these systems required frequent maintenance and repairs.
