Publication Authors *Ariyo T.O. , Tata H. , Omogunloye O. G.
Year Published 2016
Abstract

 Access to a secure, safe and sufficient source of fresh water is a fundamental requirement for the survival, wellbeing and socio-economic development for all humanity. The challenges face by the Lagos State Water Cooperation (LSWC) is to ensure continuous water supply for her citizen. In spite of this effort to rescue the situation, a substantial proportion of the city‘s population are yet to be served with water from the main source. One of the major challenges in water supply is the provision and management of the pipe network and the associated assets. Effective functioning of these assets is necessary for distributing water continuously and efficiently. The methodology for this research work was data acquisition, geo-referencing and digitizing, data integration, data analysis and manipulation, data display as maps, charts and tables. Analysis and result for this research works shows that LSWC is made up of 22 Project Control Units (PCUs), from which analysis shows that population is higher than water supply in Lagos West, Owode, OluteKirikiri, Ajegunle, Victoria Island, Itire among other. Water supply as regard to population ranges between 0 – 0.94 g/c/d whereas on the other hand, water supply is higher in Iseri Oke, Isolo, Shomolu, Surulere, Yaba and Lagos/Ikoyi ranging from 1.09 – 8.71 g/c/d. The study shows that water is in short supply and with the use of a GIS software has showed the expected water supply within Lagos Metropolis. Some of the factors that have been identified as important controls on water demands in the study area include increase in population, increase standard of living and purchasing power, changes in social tastes and policy decisions. Unfortunately, LSWC is unable to meet the growing water demand of the people due to: inadequate water facilities such as network distribution, water works (reservoirs), inadequate power supply, poor state of some of the equipment, reckless over-consumption and misuse of water amongst others.

Publication Title Mapping And Spatial Distribution Of Petroleum Products By Marketers In Nigeria
Publication Authors *Tata H., Ariyo T.O. & Omogunloye O. G.
Year Published 2016
Abstract

Nigeria is  endowed  with abundant natural resources of  which petroleum resources play  a dominant role in the economy. These resources can be effectively harnessed and managed for the benefit of all Nigerians. Unfortunately, the distribution of petroleum products in the Nigerian economy is fraught with complex problems resulting sometimes in petroleum products outages, inflated prices of products and contentions on the pump price of products. The aim of this paper is  not only to  evaluate the  distribution of petroleum products in the  country but  to  apply Geographical Information System (GIS) to highlight distribution weakness in the country. The research work was carried out using data acquired from NNPC, PPPRA and NEITI. These data was processed using GIS. The findings from the study show that the distribution system of petroleum products in Nigeria is ineffective and inefficient due to a number of factors which have been identified. To meet all this demand for these products without provoking market imbalances, the right supply levels are needed. Measuring this is always a challenge for the experts  who  work  in  the  oil  industry. Thus,  the  use  of  GIS  should  be  employed in  the downstream sector of oil industry.

Publication Title COMPARATIVE ANALYSIS OF POSITIONAL RESULTS OF POST PROCESSED GPS SURVEY DATA USING THREE TRIMBLE SOFTWARE PACKAGES
Publication Authors Tukka, A. A.*, Dodo, J. D.** and Ariyo, T. O.

Abstract

In Global Positioning System (GPS) survey, post processing technique has proved to be the most efficient means of obtaining precise and accurate positional results. Different types of post-processing software are available and surveyors use them at random without knowing their comparative efficacy. Trimble software packages can be used to post process GPS data in order to determine final positions of points on earth’s surface. However, these packages have not been compared to determine which of the software is better than the others under certain circumstances. Therefore, this study attempts to assess and compare positional results of points obtained using Trimble Business Centre (TBC), Trimble Total Control (TTC) and Trimble Geomatics Office (TGO) software for post processing GPS survey data of the same study area. The survey data was processed at 150, 250 and 350 satellite elevation angle using 24 hours GPS (at 30 seconds interval) RINEX data of four stations. These are FUTY Continuously Operating Reference System (FUTY CORS), DDD1, DDD2 and DDD3 stations for GPS week 1622 and Day 40. The results obtained revealed that TBC has the least Root Mean Square Errors (RMSE) and Trace of variance-covariance matrix in the baseline domain. Also, in the coordinate domain, TBC gave the least value of coordinate variance. TGO produced the highest values of RMSE and Trace of variance-covariance matrix in the baseline domain and also the highest variance in coordinate domain. Therefore, TBC was found to give more consistent and satisfactory positional results than TGO and TTC. Hence, TBC is recommended, as the most appropriate commercial software for post processing GPS surveying data.

Publication Title Developing And Consuming Mobile Location-Based Systems
Publication Authors Omogunloye O. G., Ariyo, T. O., Falebita M. A., Oladiboye O. E.
Year Published 2016
Abstract

The convergence of the internet, wireless and location technologies has been creating new opportunities for mobile devices. Mobile location-based system (MLBS) has emerged as a critical field of study in mobile communication. The study investigates the technologies used to develop Location-Based Systems (LBS) and describes various methods of consuming such systems. It features significant programming logics and processes needed to successfully implement an adequate Location-Based System. To explore this cutting-edge technology in a user-friendly manner, a real-world application was developed to demonstrate the processes and platforms deployed to consume LBS. The demo which could be deployed on seven different platforms including Android, Blackberry, Symbian etc, utilizes legacy data storage based on Microsoft.Net Windows Communication Foundation WCF (Restful Services) and MS SQL Server. The developed product is a hybrid application that helps mobile user find businesses and places closest to them or in their suggested area in order of proximity. The work demonstrates practicable solution to developing and consuming multi-platform, light weight, cross-domain mobile enabled Location-Based Systems.
