Description

Digital data of 3D models featuring geometry model, texture map and textual attribute to represent the geometrical shape, appearance and position of three types of ground objects i.e. Building, Infrastructure and Terrain in Max, 3ds, FBX and VRML formats.

3D Spatial Data 3D-BIT00 (CSDI Portal)

The 3D Spatial Dataset consists of three major types of ground objects i.e. Building, Infrastructure, and Terrain. The building models are classified into Level 1, 2 and 3 to represent different level of details to the physical building. All buildings and/or podium with footprint area greater than 4 sq. meters in B1000 digital topographic map are constructed to 3D building model and classified as Level 1 building model which mean that are extruded from the footprint of a building tower and/or podium with the relevant building base and top level but do not apply photorealistic texture. Those prominent buildings with land mark importance are constructed to Level 2 and Level 3 building models with photorealistic texture applied to surface of model. The difference of Level 3 from Level 2 is the model with reference to the architecture drawings from other departments. The infrastructure model includes major roads and bridges that are 3 dimensional representation of road on 3D surfaces and bridge in wireframe model including surfaces, parapets, girders, supporting columns and towers respectively. Terrain model is represented by Triangular Network Model (TIN) derived from available breaklines and height points from various sources with attachment of an orthophoto images. The Terrain model is a Digital Elevation Model (DEM) to represent the elevation of bare ground.
