TOPOGRAPHICAL INFORMATION OF PART OF INSTITUTE OF TECHNOLOGY (IOT) ADEWOLE, ILORIN KWARA STATE
Abstract
Topographic information system is very essential in this present age in other to be able to update map and retrieve necessary data at any given time with minimal efforts. Topographic information can be explained as the combination of human effort and computer-base tools for the collection, storage, analysis, manipulation and retrieval of various kind of data relating to geographic features (Man-made and natural) on the surface of the earth. It is necessary to create topographic information system for different location because the information generated from such system can be used for various purpose in physical planning and decision making in such location, The aim of the project is to produce an update topographical information of institute of technology Adewole Ilorin, kwara state for the effective use of people and for people to have access to it from any part of the world via Topographical information system, via field and office reconnaissance in other to be familiar to the study area, using the digital instrument Differential Global Positioning System South model NTS 455 to acquired spatial data (X, Y, Z coordinates) within the study.The data processing were adequately and effectively done by using AutoCAD 2007, ArcGIS 10.5, Surfer were used for the spatial analysis, query generation and information presentation. The result shows the database design of spatial database, perimeter plan, detail plan, contour plan, composite topographic map, and testing of query and analysis.
