Land Use/Land Cover Analysis Using Remote Sensing and GIS: A Case Study of The Polytechnic Ibadan, Oyo State, Nigeria (2005, 2010 and 2015)

Abstract

This study therefore examines the Land use/land cover analysis of The Polytechnic Ibadan using remote sensing and GIS. Landsat TM imagery of 2005, 2010 and 2015 was used to identify and classify the assessment spatial changes that have occurred in the institution between the year of the study. A GIS database of the study area and their location within the interval of 5years (2005-2010-2015) was generated and analyzed with the aid of GIS analytical functions. These includes: Land use/land cover classification using ArcGIS 10.2 Software and ILWIS 3.4. The result showed that the intensive rate of admitting students and insufficient administrative and academic offices has resulted in spatial changes in land cover land use between 2005_2010 and 2015. It also shows that population growth among student admitted as well as the need in more administrative and academic offices in the institution imposes a lot of pressure on the institution in providing a conducive environment. This research highlights the increasing rate of student admitted which leads to creation of additional infrastructural facilities by the institution and the need to apprehend the situation to ensure sustainable environmental development.
