The study aimed at using geovisualisation method for guiding structural height restriction around the airport. In Nigeria, there is a growing demand for Airports and safety is paramount to aviation industry as calamity is irreversible. In respect of this, precautionary measures are better emplaced at inception to safeguard the industry as much as possible. For example, failure because of engine faults in flight cannot be completely erased, at least, planes hitting buildings due to either low altitude of the airplane or excessive height of structures could be totally abated. Data used for this study involved Geospatially acquired data obtained through primary and secondary methods. The data were processed and a 2km buffer zone was created around the proposed airport for analysis. Modelling of the study was done to relatively deci...

Data used for this study involved Geospatially acquired data obtained through primary and secondary methods. The data were processed and a 2km buffer zone was created around the proposed airport for analysis. Modelling of the study was done to relatively decipher the height relationship between the airport runway and the buffer zone. Hypotenuse theorem was used and available data, airplane altitude along various directions were calculated in relation to the mean sea level through which proposed heights restrictions were made for structures within the buffer zone in the study area. It was scientifically deduced that using of only number of building ,floors and other structures, the height above earth surface are not enough to set such height restriction, instead, elevations of adjoining land should also be a striking factor taken into set structural height restriction aided by Geo observation data.

Differences in their area of emphasis and interest notwithstanding, these specialists have a common objective - they wish to model the surface of the earth i.e. describe and represent the surface of the earth conveniently and with certain accuracy. This project was attempted to generate a Digital Surface Model (DSM) for Emmanuel Alayande College of Education, Oyo, Oyo West Local Government Area, Oyo State. Reconnaissance was first of all carried out. Spatial data was acquired directly from the field using automated ground survey method (Sokkia 550+Total Station) in order to keep pace with currently available advanced technology and required accuracy of data. Non-spatial data was obtained through social survey by oral interview method and visual perception. The acquired data were later processed and analysed. Graphic representation of the processed data was carried out with Computer Aided Design (CAD) software specifically AutoCAD 2010 and Surfer 9. The designed database was implemented using ESRI’s Geographic Information Software ArcGIS 9.3, creating room for analytical operations like spatial analysis and spatial search to be performed on the created database. Analyses performed gave rise to digital information in form of Digital Surface Models, maps, and plans. Some queries were generated to enable spatial search on the database created and transform such dataset into an information system which then support decision making process in different area of application effectively.

All human activities take place in space or in other words at particular location, viable information about which is indispensable if one is to ensure they are effectively and sustainably executed. This geoinformation are obtained from an array of sources through various means and methods ranging from conventional land survey to high-tech Geographic Information Systems. Geomatics refers to any technology or business service associated with two or three-dimensional mapping, from environmental pollution monitoring, to directional well drilling, to automated tractors that through global positioning systems (GPS) and computer technology are literally able to steer themselves. The various products of Geoinformation Systems find application even in the least of day to day activities and ultimately in the region of effective planning and execution of construction and urban development and renewal projects. As an important contributor towards actualizing the Millennium Development Goals (MDGs), Geoinformatics equally double as a veritable gold mine for upcoming and goal driven youths as it provides enabling grounds for productivity and self-dependency. All that is needed for a start is only a personal computer, an adequate knowledge of information technology and access to the internet. A good business strategy of identifying who needs a particular product, as geoinformatics has the capability of generating various end products from the same datasets, is highly essential and publicizing it to the targeted end user.

This study uses GIS to investigate the water distribution network of Federal School of Surveying, Oyo, Oyo East L.G.A. Oyo state, Nigeria. The objective is to create a geo-database that supports improved operations and performance for the purpose of serving as a Decision Support System (DSS). The data as used were the downloaded satellite imagery (raster data) covering the study area, ground coordinates (vector data) obtained through automated ground surveying techniques and attribute data obtained through social survey. Different analyses were performed to demonstrate the effectiveness of the application of GIS in the management and administration of efficient water distribution network. The generated results can be employed to facilitate decision making processes towards realization of a sustainable water distribution networks cum management. The study has further demonstrated the suitability of GIS techniques in studying water distribution networks for effective administration and management.
