Lagos city is a mega city and the hub of many economic activities. There is a high influx of people into Lagos on a daily basis and the population growth is also on the increase. The state has experienced a population growth that is rapid over the years and this has brought about an increase in the need for rapid expansion of land use activities for commercial, residential, industrial among several other uses. There is also the expansion of cities into sub-urban areas and more areas are witnessing development. Land reclamation is also an activity that has increased land area for various uses and places that were formerly swampy have been converted into dry ground on which various activities are carried out. It is important to know the rate at which land is being used and the factor responsible for this. An important way of achieving this is to have a broad aerial view of the area under study and also to use special software to analyze this data. The best way to achieve this is through the use of Remote Sensing Technology while GIS assist in providing analytical tools that can be used to provide adequate information on which decision that will be made in the future. 1.2 STATEMENT OF THE RESEARCH PROBLEM
There is the need to know the cause of administration problems with a view to providing a lasting solution that works in line with sustainable development. In Lagos it has been observed that land is a major platform in human activities and it is where human activities take place. Land use in Lagos has over the years undergone rapid changes and many open spaces have been converted into residential, commercial, industrial and several other uses. There are also a lot of conflicts, policy issues, legislations as well as political issues that go into the way land is being used and there is no means of gathering useful spatial information and analytical tools that will constantly provide information on land use and pattern of growth in Lagos. The use of Remote Sensing and GIS provide the means through which land information and growth pattern can be analyzed with the use of the latest technology.
1.3 AIM OF THE STUDY
This study investigates the implications of the rapid expansion of metropolitan Lagos for land administration using Geographic Information Systems (GIS) and Remote sensing technology. This is intended to enable planners and policy-makers contribute to improved land administration and enhance their competence in decision-making.
The objectives of this study include
1. Capturing of data for analysis
2. To design a decision support tool for land administration 3. To demonstrate how latest advances in geospatial information can guide planners and policy makers towards an improved land administration 4. Presentation of findings and recommendation for sustainable development.
1.5 THE STUDY AREA: LAGOS STATE
Lagos state is situated in the South Western Nigeria within latitudes 6 degrees 23’N and Longitude 2 degrees and 3 degrees 42 E. The state is bounded from the North and East by Ogun State, in the West by the Republic of Benin and the South by the Atlantic Ocean. The total land mass of the state stretches over 3,345 kilometers. While the state appears physically smaller, it is ranked as the most highly populated state in the country with an estimated population of about 10 million inhabitants representing 10 % of the total population of Nigeria. Because water is the most significant topographical feature in Lagos State, water and wetlands cover 40% of the total land area in the...
