Abstract:
This project centers on the creation of cadastral information system for part of Kosobo phase iii, part 1, in Oyo east local government area of Oyo state. This study describes the design and implementation of a cadastral database with a spatial modeling approach. The objectives are to propose a design of a spatial database that fulfils the requirement for spatial queries for cadastral data. Implementing this design in the study area and enforce the development of multipurpose-motivated cadastral data. In order to meet the study objectives, the required characteristic of a cadastral database was taken into consideration while performing the design. The phases followed during database design process include the conceptual design, the logical design, the data acquisition, physical design, analysis and the implementation of the database system. Attribute data was obtained through questionnaire and oral interview. the graphic drafting was done in AutoCAD land development while Arc view was used for data analysis, queries and presentation. Queries were performed and generated to demonstrate the capabilities of the software used and the database created.

Introduction:
For decades, traditional cadastral system have tended to enjoy a reputation for reliability, well defined processes and a well recognized guarantee of security to private land ownership. Tremendous technological progress, social changes, globalization and increasing intercommunication of business relation with their legal and environmental consequences however it has put a strain on the traditional systems. They cannot adapt to all new developments. An obvious indication of this is many reforms that cadastral systems are going through.
One of these reforms is the application of GIS in cadastral management which is the automation of the old cadastral system by employing modern information observational techniques to ensure fast and efficient services. In consequence cadastral information system in being used to improve services of the cadastral systems. While automation of cadastral system is widely seen as an appropriate tool to improve the performance of the system. Automation however of the traditional perfectible system without re-engineer the procedure aspects may result in performance failure example of this is changes in data processing and presentation.
Until recently, the method of producing cadastral information has been manual opto–mechanical using analogue equipment and generating analogue map database. The analogue procedures and product generation is associated with many problem. These include:
i The equipment are cumbersome and bulky to be carried about.
ii The methods of surveying are labourious and slow.
iii When large area are to be mapped, it easily break down especially during raining season.
iv It is expensive in terms of production and management
The output which is in analogue paper map as database also has the following limitations.
i There is loss of information over time as the map could shrink
ii Once data had been put into map, it is neither easy nor cheap to retrieve or combine them with other spatial data.
iii the printed map is a static qualitative document.
Recent advances in cadastral information system has led to guarantee of title, legal security, fast services for users, complete coverage, comprehensive liable secure system in computerized and automated, Digital data system serves other purposes (i.e. as basis for LIS) integration of different system land registration and cadastral mapping.
