© 2022 Global Journals 1 Global Journal of Science Frontier Research Volume XXII Issue V Year 2022 34 ( H ) Version I Using Remote Sensing and GIS to Investigate the Effect of Urban Sprawl on Health Facilities in Egbeda Local Government Area, Ibadan, Oyo State, Nigeria as shape files for statistical analysis and mapping. Also Geographical Positioning System (GPS) was used to identify the health institutions and obtain the coordinates of the location of each identified health facilities. These were loaded on the imagery of Egbeda Local Government Area that was digitized from the images using the software of ArcGIS 10.2 . IV. R esults and D iscussion The changes that occurred in Land use and Land cover in Egbeda Laocal Government Area, Oyo State for the past 34 years are shown in the following landuse and land cover maps of Figure 2 and Table 1. However, the total area of each of the landuse and land cover was calculated in 1984, 2006 and 2018. Table 1 is the summary of the area coverage in areas and percentage of land use and land cover types under study which includes the total area covered by the classification. Figure 2 shows the three years tend pattern from 1984 to 2018. In 1984, bare surface, cultivation, built up, vegetation and water body measures 0.0788%, 10.5660%, 9.8148%, 78.5841%, and 0.9563%, respectively. In 2006, bare surface lost from 0% to 0%, cultivation gained from 10.5660% to 13.4195%, built up also gained from 9.8148% to 21.4131%, vegetation lost from 78.5841% to 64.0343% while water body also gained from 0.9563% to 1.1331%. In 2018, bare surface remains the same, cultivation and vegetation lost from 13.42% to 3.6%, and 64.03% to 62.41% respectively, while built up and water body all gained from 21.41% to 35.80% and 1.13% to 1.23 % respectively. It shows that there is a continuous increase in built up area from 25.4565Km² in 1984 to 84.5118Km² in 2018. This shows that land use from 1984 to 2018 with an increase of 59.0553Km², this shows that there is an increase of more than 50% within those years.
