APPLICATION OF GROUND SURVEY AND GEOGRAPHIC INFORMATION SYSTEM (GIS) IN PRODUCTION OF DIGITAL MAP OF ABUBAKAR TATARI ALI POLYTECHNIC, MAIN CAMPUS, BAUCHI, BAUCHI STATE

Abstract

This study employed GIS techniques to produce a digital map of Abubakar Tatari Ali polytechnic, Bauchi. A total station was used to obtain rectangular coordinates (Easting, Northing and Height) of natural and artificial features within the polytechnic. These features include; building, electric poles, roads, streams, sport heights, etc. The coordinates were later typed in notepad and exported to AutoCAD software for plotting (script plotting). Each feature was plotted as independent thematic layer. The layers were exported to ARCVIEW software for generation of contour lines and compilation. The map was produced indifferent layers, namely; boundary, building, contour, road, stream and utility. The layers were superimposed on one another to form a composite map. From the study, the digital map of Abubakar Tatari Ali polytechnic, Bauchi was produced and hence is recommended that digital mapping should be embraced because of its flexibility to handle data in layers and assurance of dimensional stability of storage medium, eliminates loss of data or details in transfer from one medium to another and maintains positional accuracy since the data are held in digital form.
