Description Of The Project Title
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

Multisource Data Integration to Prepare a Interactive 3D Model of
Kathmandu University



A digital representation of
features, either real or
hypothetical, in threedimensional space



3D models represent a 3D
object using a collection of
points in 3D space, connected
by various geometric entities
such as triangles, lines, curved
surfaces, etc

Some Common 3D File Formats

COLLABORATIVE DESIGN ACTIVITY
 An open-standard XML format for
storing 3D models.

ABC – Alembic (Computer Graphics)



BLEND – Blender(.blend)
CTM – OpenCTM(.ctm)
DAE – COLLADA (.dae)
MRC – voxels in cryo-electron
microscopy

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
U3D – Universal 3D file format (.u3d)
analysis results with others and also
provides a mechanism for updating
VRML97 - VRML Virtual reality modeling
textured 3D GIS data, such as buildings,
language (.wrl)
using third-party software like

Kathmandu University
Computerized maps that allow users to interface
with various aspects of the maps themselves.
Offers following major options to the map user
 Zooming in or out on a specified location,


Panning easily between geographic areas

 planning driving routes and Geocoding
 Providing street/satellite views of a desired
locale.

 Permitting professionals the ability to interact,

Rationale: Why This Project
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.

Objectives Of The Study
The main objective of the study is to prepare the 3D virtual model of the
Kathmandu University showing the photo realistic buildings, roads, boundary,
and other living as well as the inanimate features.
The main objectives are followed by following sub objectives:

•To integrate the spatial data obtained from the heterogeneous sources.
To prepare a Geo database of Kathmandu University
•To prepare the interactive map where users can request different aspects of
map viewing.
•To upload the interactive map on the web portal for multi user access as a
means of map dissemination.

Limitations Of The Study
This study has been undertaken in the view of meeting the partial fulfillment of the
Engineering Project, GEOM 307. The study had to be completed within the limited
time frame and resource limitations.

1.Resource limitation:

The limited budget constrained for the quality data, high precision
instruments i.e. Satellite Images and good working environment
i.e. High speed internet, (For downloading the textures, Images and Google
Earth Integration)

High computer processors (For simultaneous use of various software )

2D Editing

3D Editing

Arc map

Arc Scene

 One of the 3 main component that
make up ArcGIS.

 A software to visualize features
in 3D by providing height
information from feature
geometry, feature attributes,
layer properties, or a defined
3D surface (such as a digital
elevation model, or DEM)

 An interface that allows users to
view data sets together,
perform analysis and create maps
 All 2d mapping works were performed
in Arc map Version 10
 Arc map version 10 provides an easy
interface for mapping functionality

 Arc Scene version 10.0 have
got advance 3d editing tools

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


which ensures that 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.

3d Editing - Arc Scene
 Arc Scene allows 3D editing environment and offers more edit tool
options specific to multipatches
 Editing in 3D is designed to work with the 3D Analyst extension in
ArcScene



3D editor tools are easily available from a dock able toolbar and a pulldown 3D Editor menu

 All tools provide real-time surface feedback, which permits you to save
your edits directly back the document or undo your changes.

Multipatch feature

 A GIS object that stores a collection of patches to represent the boundary of
a 3D object as a single row in a database
 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.

Conclusion and Recommendation
 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 .
