Description Of The Project Title
Multisource Data Integration to Prepare The Interactive 3D Model of Kathmandu University
Multisource Data Integration to Prepare a Interactive 3D Model of Kathmandu University
Spatial data acquired from different heterogeneous sources are being input into a common data base
The use of different data sources brings along many challenges.
For example, multiple data formats, various accuracies, coordinate systems and level of details must be taken into consideration

Some Common 3D File Formats
ABC – Alembic (Computer Graphics)
BLEND – Blender(.blend)
CTM – OpenCTM(.ctm)
DAE – COLLADA (.dae)
MRC – voxels in cryo-electron microscopy
U3D – Universal 3D file format (.u3d)
VRML97 - VRML Virtual reality modeling language (.wrl)
COLLABORATIVE DESIGN ACTIVITY An open-standard XML format for
storing 3D models.
Often used as an interchange format for 3D applications.
Also format for 3D textured objects stored inside KML.
File extension: .dae (digital asset exchange)
Exporting multipatch features to COLLADA allows sharing of complex analysis results with others and also provides a mechanism for updating textured 3D GIS data, such as buildings, using third-party software like SketchUp

Rationale: Why This Project
Multisource Data Integration to Prepare The Interactive 3D Model of Kathmandu University
Kathmandu University being the leading institution of Nepal doesn’t have any means to disseminate the University map portals among its visitors, students and other stake holders
The two dimensional master plan without any spatial reference is still serving as the tool to visualize the spatial position of the University components
So a necessity of three dimensional map was felt which could serve as a tool to visualize all the features along with the terrain in digital form with the web access.

TIN representation of the terrain
TINs are a form of vector-based digital geographic data and are constructed by triangulating a set of vertices (points).
The vertices are connected with a series of edges to form a network of triangles following Delaunay triangulation

INTERACTIVE TIN EDIITNG
The resulting triangulation satisfies the Delaunay triangle criterion
No vertex lies within the interior of any of the circumcircles of the triangles in the network.
If the Delaunay criterion is satisfied everywhere on the TIN, the minimum interior angle of all triangles is maximized.
The result is that long, thin triangles are avoided as much as possible.

Contain 3D models with vertical and overhanging faces allowing the creation of photorealistic 3D views.
Can contain texture information, such as a digital photograph of the front of a building.
Is stored in the Geodatabase or shapefiles in the same manner as point, line, and polygon data.

Multisource Data Integration to Prepare The Interactive 3D Model of Kathmandu University
Multisource data integration is often a complex task and involves the series of coordinate transformation and file formats interpolability issues.
The users of today’s era wants map to be more interactive and user friendly.
Accurate 3D modeling of the any geographical location first seeks the quality data with completeness and correctness and also the excellent working environment .
Establishment of the web server is the effective means of disseminating
the maps among the variety of users . A complete 3D model can be build for better visualization and information
