- Abstract
This paper aimed to access the impact of our present government as per developments is concerned which can be detect and access through satellite imagery using geospatial technology in Ekiti Central Senatorial District, South Western Nigeria. This research cover 31 years epoch which was analysed using multi-temporal satellite imageries of Landsat (TM) images of 1986, Enhanced Thematic Mapping plus (ETM+) images of 2002 and 2017 along with recent Google earth imagery. The study also employed GIS software such as ArcGIS 10.2, Erdas Imagine, QGIS and Idrisi selva for supervised images classification method, preprocessing and accuracy assessment, acquisition of some vector layers and prediction and modelled between 2017 and 2032 respectively. The land use was classified into various land use classes such as built-up, water body, forest, wetland, farmland and exposed surface along with their statistical values which helps to determine the consequence of anthropogenic activities in the area. The results show that built-up area covered 73.53 kmsq, 93.98 kmsq, and 124.59 kmsq of the land area and constituted 4.8990%, 6.261%, and 8.2996% in 1986, 2002 and 2017 respectively while 152.47 kmsq and 10.16% was generated for year 2032 as prediction land use using model in Idrisi Sleva software and this constituted the most extensive type of land use/land cover in the study area. The increasing population and economic activities were noted to be putting pressure on the available land resources due to government intervention in the area. This paper highlights the land use/land cover types, the change over the years and the causes of the changes scenario. The importance of Remote Sensing and GIS techniques in mapping and change detection was also highlighted. The aim of this research paper is to carry out assessment of the level of development in Ekiti Central Senitorial District with a major focus on the causes of the rapid development which is obviously government policy. Over the years the government has cited some facilities in this area, hence the rapid rate of development. The development over the years can be technically analyzed with access to satellite imageries using geospatial techniques. Key words: TM, ETM+, QGIS , ARCGIS, Satellite Imagery and Geospatial techniques.
