This document discusses the development of a WebGIS-based Land Information System for Balangoda Urban Council using open source software. The key points are: 1. The system will develop digital maps connected to a spatial database for land management and tax procedures. It will publish maps through a web interface for public access and spatial analysis. 2. The system aims to visualize 3D building information like heights and number of stories. 3. The research will only use open source software to develop a low-cost system that is important for developing countries like Sri Lanka.

2. 1.0 Introduction
1.1 General Background
LIS
• Legal, administrative and economic decision making in order
to planning and development of land
10/9/2012
• Database containing spatially referenced land related data for
a defined area
• Procedures and techniques for the systematic collection,

updating, processing and distribution of that data
Modern trend is to publish LIS as GIS services

4. 1.2 Land related problems of Balangoda
Urban Council
1. Land management problems
• Land degradation
• Finding suitable places for each type of purpose
10/9/2012
2. Tax payment procedure problems
Research Presentation
• Time and Accuracy
• Updating
• Multi storeys buildings having different owners
• Large number of human power
3. Data Sharing
• between different sections in UC
• visualize those data to people 4
4. Software cost

Main Problem
How to develop webGIS based LIS using only open source software
having 3D information as well?
10/9/2012
Secondary Problems
Research Presentation
1. How to make digital maps which connecting to data base for
doing land management and effective tax procedure?
2. How to publish created digital maps through WWW keeping
capable of doing spatial analyzing and quick input and output?
3. How to visualize 3D information on the map?

8. 1.6 Significance of the Research
Land Information System,
1. Digital
• Easy and effective spatial data management and storage
capability
10/9/2012
• Can update and retrieve information easily
2. Web Based
Research Presentation
• Can access to data freely and quickly to general people and
another government and private companies.
• Easy to share data between different section of UCs
3. Querying data
• Land use planning
• Land administration 8
• Design making in situation like natural disaster etc

9. 1.6 Significance of the Research
4. 3D Land Information
10/9/2012
Research Presentation
 3D information in this research
1. Height of Buildings
2. Number of storeys of building
3. Owner name of each storey of one building
4. Visualization of cartographic 3D view of building
5. Open Source
• No any sort of software cost for developing using and updating of
system 9
• Very important for developing countries like Sri Lanka

10. 1.7 Limitation of Research
• Balangoda Urban Council
1. Very interesting to use new technology.
10/9/2012
2. Completely finished government title registration
programme.
3. Nearest Urban Council from Sabaragamuwa University.
Research Presentation
• Not consider entire UC’s area as study area
1. Within given time period can’t collect ,input such amount of
data.
2. Can’t get all UC’s area’s cadastral layer from Survey
Department 10

11. 1.8 Study area
• Most important area
in Balangoda UC.

Information System (LIS) allows any individual to gather
information regarding land holding.
The web based plot wise information system provides the facility
for ready and immediate extraction of information regarding land
ownership and built up history”.

A WebGIS and geodatabase for Florida’s wetlands 2004
(Mathiyalagana V. ,et al.,2004)

“There is need to develop more Web-based tools to share
environmental datasets and information.
Research Presentation
Decision-makers and administrators often have limited
expertise in GIS and complex spatial analyses.
WebGIS has the potential to share data, provide easy access
for users with limited GIS knowledge

3D Cadastre ,
Jantine Esther STOTER (2004)
“It can be concluded that a full 3D cadastre that both registers

surface parcels and volume parcels offers best potentials and is
realizable”. Cases in Queensland, British Columbia, Norway and
Research Presentation
Sweden showed already that it is possible to establish volume
parcels within the juridical frameworks.”
“This thesis showed that it is possible to register volume parcels
together with 2.5D surfaces of parcels within a cadastral and
technical framework”.
