3D city models are basically a computerized or digital model of a city contains the graphic representation of buildings and other objects in 2.5 or 3D.
Generally three main Geomatics approach are using for Virtual 3-D City models generation, in first approach, researcher are using Conventional techniques such as Vector Map data, DEM, Aerial images, second approach are based on High resolution satellite images with LASER scanning, In third method, many researcher are using Terrestrial images by using Close Range Photogrammetry with DSM & Texture mapping.
Heh, yeah, I know I started this several years ago, but what can I say; that one I never finished, and even if I DON'T finish this one, I've still made at least a lot more progress on it than I did with the last one. It's not something that's gonna be knocked up in a couple of weeks.
It could even take me up to a couple of YEARS, although given how much I have already done in comparison to how big the CBD is, it shouldn't take years and years.
The moment-to-moment gameplay involves purchasing property for the railroad corporation, building out tracks from place to place, and configuring trains of various types and sizes to take certain trips at certain times.
If you want, you can even sit back and watch the train go around the city, though you should know that doing that is just as productive as it sounds.
It's being built in sketchup, and imported into Google Earth.
When it's finished, I'll release it as a single big Sketchup file, which you can then import straight into Google Earth as a single model.
While Sim City found success by making a larger and larger sandbox in which to create, A-Train took a different path. It manages its city building more indirectly, using a railroad corporation’s expansion (and occasional side venture investments) as a foundation for urban growth.Individual buildings, for example, can be selected and downloaded over a service interface in a variety of 3D data formats.The model provides a unique foundation for research and development for technology-based companies, startups in the digital economy and scientific institutions.In the wake of the most recent Sim City’s crash-and-burn reception, it seems like an apt time for other city-builders to finally grab a piece of the limelight.And while Cities: Skylines seeks to recapture what made classic Sim City great, A-Train 3D: City Simulator stays right where it’s always been and hopes the public will finally notice.
