Development of a Land Information System of Tumpure Residential and Commercial Layout in Akko Local Government Area of Gombe State

Abstract

The study has to do with the method and steps in creation and development of a Land Information System (LIS) for Tumpure residential and commercial layout in Akko Local Government Area (LGA) of Gombe State. This involved the creation and testing a multimedia relational database of the attributes of the individual parcels which were linked to the polygonized spatial positions of the parcels in Geographic Information Systems (GIS) in Arcview 3.2a software environment. The analogue layout plan of the area of study was acquired, scanned, Georeferenced and digitized in AutoCAD 2000i environment. The digitized layers were then exported into the Arcview 3.2a software for parcel polygonization and subsequent table creation and linkage to the graphics. Video clips and snap shots of buildings and other special features obtained from individual parcels were recorded with digital camera and linked to their respective parcels in the Arcview software. High resolution satellite imagery covering the layout was obtained from Google Earth, Georeferenced and overlaid with the parcel layer to reveal the features contained in each parcel pictorially. The structured information contained in the database was evaluated and tested and found to be easily and readily accessible and retrievable through locational and attribute queries. The results demonstrated the efficacy of the system. Adequate recommendations were also made.
