3D City Modelling made easy in uSMART

TIN Imaging: drape images onto triangles/shapes over massive areas

Although the Mass Data Module is not the only Module used for 3D City Modelling in uSMART, it is an integral part of the process. There are essentially six easy steps to create 3D City models in uSMART. Please refer to our brochure 3D City Modelling Made Easy in uSMART for more details about the steps.

The unlimited capacity of the MDM allows users to accurately model whole cities, and even entire countries. Image draping is done using orthophotos and flat aerial images used in the Softcopy system. Oblique imagery is not required, images for triangles on the sides of the buildings are determined from the flat (vertical) aerial images. During the TIN Imaging (draping) process, clash detection is done for non-planimetric images, ensuring that even in dense cities the sides of the building are represented accurately.

Advantages of using the uSMART 3D City Modelling solution include the ability to navigate to any position in the city. Users are not restricted to particular view points; a user can for instance "walk" around a building and even through a building and view it from any angle. Another advantage is that the 3D buildings are very accurate and precise measurements can be done on the buildings. Details on the buildings are placed using an accurate True 3D DEM.

There are no restrictions to the size of the data set, as the MDM module is designed to overcome memory limitations and the speed of working with the data does not decrease as more data is added. It is therefore possible to add more and more data to the set. All the cities that are done may therefore be added to the same data set effectively building a 3D Model of a country, a continent or the world. There are no restrictions to what the users can do with this data. The high accuracy of the data make it ideal for survey applications such as planning and building validation yet the visual appeal make it perfect for creating fly-throughs for e.g. marketing purposes, to use in navigation systems and movie creation, etc.
