Consequently, the information requirements for land title administrations have increased. Yet the system of information collation and retrieval has remained, in most cases, unchanged leading to haphazard development of land resources with serious legal, planning, economic, and environmental impacts. This realization led to the involvement of Information Technology (IT) tools, to assist in the creation, documentation, and management of land titles. This paper describes a database application model to improve the situation. The methodology, operation, and evaluation of the system are discussed. The paper concludes that the system will provide reliable and easy system for collating information, analysis, retrieval, and monitoring trends pertaining to any particular plot of land which is invaluable for efficient land title management in Nigeria.

The demarcation is of utmost importance as it shows the extent and limit of each piece of land which is very crucial in Cadastral Science. In this paper, with the help of this popular transform, we have been able to successfully detect the boundaries and delineate the lands. With further perfection, the employment of these digital image processing algorithms could provide better alternative method over the hitherto ways being used in Plane Surveys.

IT is "an umbrella term that includes computer hardware and software; digital broadcast and telecommunications technologies as well as electronic information repositories such as the Web or those found on CD-ROMs. IT also encompasses a number of continually evolving range of elements that further includes television, radio, mobile phones, office automation equipment, electronic teaching aids, etc. This work aims to investigate the extent to which IT is being employed by Technology Incubation Center Kano to achieve its set objectives. The work also concludes that the golden aims of Technology Incubation Centers in the Country could be achieved more efficiently and more cost effectively if IT is made good use ...

Specifically edges are points where there is a boundary between two image regions. Visually, they form the outline of a feature. An edge is the boundary between a feature and its background. Technically, if edges of features are algorithmically identified and detected accurately, then all features could be located and their basic geometric properties could be determined. Similarly, these edges and forms of features are part and parcel of Cadastral Surveying and they are used to obtain the geometric values of the features, hence delineating and mapping cadastral features for the production of Cadastral plans using field oriented Surveying.Besides cadastral plans, high resolution satellite imageries have potential cadastral values as they are used to depict cadastral features. In computer vision they are used to extract linear features. The extraction of linear features or boundaries defining the extents of land...

Image enhancement approaches fall into two broad categories: Spatial domain methods and Frequency domain methods. This paper presents an implementation details of the results of the image processing application software designed using Matlab as a tool for some given ordinary images using the above mentioned methods. The designed software produces image histogram, histogram equalization of an image. Low pass and high pass filters could be applied to the imageries too. Finally having tested the application with several images, it was found to be relatively effective in both ways as contained in the results herein. Key wordsHistogram, histogram equalization, spatial domain, frequency domain

The aim of developing it was to facilitate an effective processing and display of client needs in Land Titles Management in any province as a near substitute to the conventional Geographic Information System,GIS, which is too complex and expensive to most developing countries. These countries need a cost effective,simple and web -aware system application in response to the need for computer -based tools to support the already existing stages of land information processing and dissemination in land management. The methodology,development,operation and evaluation of the model are discussed. It's methods of local access and identifying online clients(those accessing the database through the www web and Internet)are also outlined. It is concluded that this system is potentially useful in facilitation the systematic, effective, efficient and cost constrained ways of processing and displaying of client requirements to their satisfaction.

Northern region of Nigeria is part of the developing societies and is yet to fully embrace IT in regional and local developments. Investment in IT can be oriented towards consumption or production. In both cases, IT creates new jobs and entrepreneurial opportunities. The paper reviews IT vis-à-vis its relevance as a medium for development in the Northern region. The challenges that would be encountered in the process of minimizing the regional digital divide through greater IT access, for greater effectiveness and efficiency in development are as well highlighted. Some recommendations are forwarded for the attainment of a digitized Northern Nigerian region for sustainable development.

The fine spatial resolution implies that each object is an aggregation of a number of pixels in close spatial proximity, and accurate classification requires that this aspect be subtly considered. K-means clustering algorithm is a better method of classifying high resolution satellite imagery. The extracted regions are classified using a minimum distance decision rule. Several regions are selected as training samples for region classification. Each region is compared to the training samples and is assigned to its closest class. The procedure significantly reduces the mixed pixel problem suffered by most pixel based methods. In this paper, we used K-means clustering algorithm to classify satellite imagery into specific objects within it for cadastral and environmental planning purposes, thereby eliminating the above mentioned problems and getting better classification accuracy with the overall performance for accuracy percentage as 88.889% and Kappa values as 0.835.

Yet a condition for market driven economies encompasses not only deregulation and privatization of resources but also transparency, accessibility and ease of transaction of whatever kind. Land and land resources have become the basis of most economic enterprises. This paper uses the SQL server and dynamic web approach to illustrate the use of online Cadastral system for the management and extraction of individual land information by Title holders from a web server. The system provides an interactive medium not only for the owners to use, view, access, pass information and receive same without physically visiting the office, but also for Planners, Surveyors and Administrators to do same. Thus the proliferation of internet access has removed the hitherto geographical barriers. The system besides being cheap is efficient, convenient...

They are used to extract linear features, like roads, etc. These linear features extractions are important operations in computer vision. Computer vision has varied applications in photogrammetric, hydrographic, cartographic and remote sensing tasks. The extraction of linear features or boundaries defining the extents of lands, land covers features are equally important in Cadastral Surveying. Cadastral Surveying is the cornerstone of any Cadastral System. A two dimensional cadastral plan is a model which represents both the cadastral and geometrical information of a two dimensional labeled Image. This paper aims at using and widening the concepts of high resolution Satellite imagery data for extracting representations of cadastral boundaries using image processing algorithms, hence minimizing the human interventions. The Satellite imagery is firstly rectified hence establishing the satellite imagery in the corr...

Consequently, they suffer in the midst of plenty due to lack of appropriate knowledge. To address the problem of poverty, we seek ways to provide the vital information to all, who are mostly in the rural areas, through IT, which is the processing, storing, and distribution of Information electronically. The question, which requires urgent answer, is considering the age long problem of neglect, access to and unwholesome decay of these rural areas, how can the much needed information that will transform them be accurately and timely delivered? The issues and strategies that need to be addressed which may provide the answer, are the focus of this paper. It is expected that if what is highlighted in this paper is carefully considered and implemented, it will transform our rural areas through generation of employment and poverty reduction. It will also increase in th...

The former have higher spatial resolutions while the latter have relatively lower spatial resolutions but are rich in spectral information. The two types of images have complementary features of spatial and spectral resolutions as such could be fused or merged to produce a better imagery that would be used in land use classification, cadastral feature analysis, change detection, maps updates, hazards monitoring and many other land related applications as well as for general quantitative image analysis. Image fusion quality evaluation approaches are divided into two main categories: qualitative and quantitative evaluation approaches. In qualitative approach, quantifying image quality is done through subjective means by human experts, whereas quantitative evaluation is based on objective performance assessments of the fusion processes. Registration of images that may be used as reference in image quality m...
