摘要：This workscrutinize the integration of Geographic information system (GIS) and remote sensing in mapping of land use/land cover of Geidam local Government area of Yobe state, where the changes that took place within the period was examine by processing the Landsat 7 Enhanced Thematic Mapper Plus (ETM+) of the year 2000, Landsat 8 Operational Land Imager(OLI) of the year 2016 and 2020. The images were processed in ERDAS imagine 2014 and ArcGIS 10.6 software packages the classified image was tested and the accuracy assessment was 92.45% and the Kappa (K^) was 0.9025 which is within the tolerance limit. The results after processing revealed that between the year 2000 and 2016, there is proliferation in water body, settlements, farmlands and vegetation by 0.51%, 0.06%, 1.30% and 5.30% respectively and there is diminution of 7.17% in bare soil class.However, between the period of 2000 and 2020, there is also an increase in the class of water body, settlements, farmlands and vegetation cover by 1.74%, 0.22%, 6.02% and 7.80% respectively andsimilarly there is a decrease of 15.78% in bare soil class.Thus, there is an increase on the land cover within the period which include water body, settlement, farmland and vegetation neverthelessthe decrease in bare soil which might be connected with the measures taken in combating desertification in the study area.
