MAPPING AND ASSESSMENT OF FACILITIES USING REMOTE SENSING AND GEOGRAPHIC INFORMATION SYSTEM (GIS) TECHNIQUES IN LANGTANG NORTH L.G.A. OF PLATEAU STATE, NIGERIA.

Abstract

The concept of digital mapping is a well-known technique that has brought a lot of changes in the cartographic industry today. This project produced a digital map of the existing and proposed facilities / utility services in Langtang North metropolis of plateau state. A spatial database of these facilities and utility services was also created using ESRI’S ARCMAP 10 Software. The Ikonos satellite image served as a base map showing all the facilities that were visible and could be recognized. Various layers of the segment maps were obtained. These were the Road network, River and main Water pipeline. Other facilities were mapped as point maps they are: Telecommunication masts, Boreholes, Transformer stations, Petrol and Gas filling stations, Health care institutions and Recreational centers. Some facilities services required upgrading and expansion, The Borehole located in Tabbat central and the Ponzhi Tarok palace motorized borehole. The NTA/ TV community station located at Zangzat, the MTEL/ NITEL in Tabbat and the Langtang Mini stadium needed upgrading and expansion as a result of the deplorable state of facilities presently. The transformer located at the hospital junction is not meeting the required service delivery because of the problem of overload. Adequate recommendations were also made based on the study results.
