This document presents the development of a 3D spatial information system using GIS for a college campus. The system was created by developing separate layers to represent features of the campus such as buildings, routes, and boundaries. Attributes were assigned to each layer to store related information. The layers were then merged into a geospatial database in ArcGIS software. Users can perform queries on the system to locate specific features and obtain related attribute data. The 3D model allows querying spatial relationships and navigation between campus buildings.

Introduction

4. • The case study area is a campus spread over 88 hectares (220
acres )
• Campus of Indian School of Mines, Dhanbad
• comprises the academic buildings , student hostels and
residential facilities for staff
• campus area is well developed in all means which makes it
perfect for this kind of analysis
Case Study area

5. Spatial Information system

“…the purpose of geographic inquiry is to examine
relationships between geographic features collectively and to
use the relationships to describe the real-world phenomena that
map features represent.” (Clarke 2001, 182).
 Technique that enables representation, description,
measurement, comparison, and generation of spatial patterns
 is one of the persistent research and application area in
Geographic Information System (GIS)

6.  detailed mapping with aid of information technology
 GIS is used for
1. capturing the data
2. Storing the data
3. analyzing the data
4. managing the data
5. presenting the data
 Provides the infrastructure to handle the spatial data
Role of GIS ( geographic information system )

7.  provides a wide range of application and tools for
development of a well classified extensive spatial information
system
 manipulation and analysis of individual layer of spatial data
 Connecting all the information to geographic location
Role of GIS….

8. ARC GIS 9.3 version
• ArcMap
• ArcScene
• ArcCatalog
Software involved

9. Step-1 Identification of Features
 identifying the features of the campus
 CPWD map of the campus area was used to identify the
features
E.g.- Hostels , grounds,
routes ,etc.
STEPS FOR BUILDING THE DATABASE AND MODEL
CPWD map of Campus

10. • Data needed for Attributes of the geographic features
• Attributes and data depend upon the application of the information system
• For e.g. Attributes Hostels for Layer
1. Hostel name 6. Height of each floor
2. Construction year 7. warden name
3. No. of block/wings 8. contact no. of office
4. No. of rooms in each floor 9. branch of the students accommodated
5 . Total no. Of rooms
 Similarly for other layers data was collected
Step-2 Data collection

11. • In this study object based database is implied
• individual objects are represented explicitly using geometric
counterpart
• primitive spatial data objects are points, lines and polygons
Object based database ( vector database)
points lines polygons
Vector data

12.  Modeling of the features in forms of Points, lines and Polygons ( Vector Data
Types ) in form of layer
 A Geo-database was created in ArcCatalog Extension of ArcGIS -9.3.
 physical representation of the features
 Layers Created in database are as follows :
Academic buildings, Hostels , residential buildings, department, routes , boundary,
 Various Attributes were defined to associated the information with Geographic
location and store it in GIS
Step-3 Layering

13. • all layer merged to a system in ArcGis
Step-4 Merging the layers

14. Work Flow

15.  referred to as data models and
Descriptive Model
 describes the objects in landscape
view
 attempts to capture the spatial
relationships within a object (e.g. shape of the building ) and
the other objects in the landscape (e.g. distribution of buildings)
 these models can be presented in 2-D and 3-D space
Representation Model

16. 2-DView of Digitized map of the campus area

17. 3-D spatial Information System in ArcScene Software Window

18. Real time answers to question can be performed e.g.
• Location of public amenities
• How do one can go from one building to another ?
• how many students are there in this hostel ?
• who is the HOD of Mining Engineering Department ?
• and many more queries
 these queries are based on alternative views of a database
Querying and reasoning

19. Query placed to Spatial information system to find a building
If ‘Mining engineering’ building need to be found then a query
can be placed to locate the building .
Department layer properties
Definition Querry
Query Builder
name =‘mining engineering’

20. Definition query and query Builder

21. Result of query
