 2019

Up to date maps are needed for many developmental purposes. Traditional methods are slow and cumbersome. Akure Urban needs up to date maps both for monitoring and control of development in form of planning, etc. Remote Sensing and Geographical Information System tools are available to solve the problem. This paper tends to x-ray the importance of Surveying in National development from the perspective of Urban Landuse Mapping. High-Resolution satellite imagery of Akure (Quickbird of 0.7m spatial resolution) was used to map the Akure urban environment for the years 2010 and 2016, and Differential Global Positioning System (DGPS) method to obtain adequate ground control points for the purpose of georeferencing the satellite images. The study area was classified into eight existing land use classes using the segmentation algorithm of object-based image analysis (OBIA) of the e-Cognition Developer 64 software. Through GPS waypoints ground truthing for accuracy assessment of the land use classes was performed. The resultant maps were analysed with ArcGIS 10.3 version. The results showed Residential, Educational, Commercial, Community & Public Institutions, Public Utilities, Open Space & Undeveloped Land, Recreation, Industrial and Transportation as the existing land use classes in the study area; and that the 2010 and 2016 landuse maps generated had accuracies of 87.73% and kappa values of 0.832 and 0.852 respectively thus judging them to be of high accuracy and precision, hence good for analysis; as well as having the existence of both intra- and inter- land use transformations between the two epochs.Residential land use was observed to have the highest positive transformation of 18.38% while the open lands and the organised open lands experienced a decreasing transformation of 10.66% and 0.16% respectively. The results were then used to discuss the role that surveying plays in a nation's development. The research thus proofs the inevitability of the integration of Remote Sensing methodologies and the tool of Geographic Information System for landuse mapping as an invaluable tool in national development. The paper recommended the placement of surveying as first priority before, during and after any developmental processes of a nation.

Land administration system in Nigeria includes the processes of land registration, cadastral mapping, land valuation and land inventory. Developing countries particularly Nigeria is faced with challenges of poor land administration and management. However, whatever the stage of the development of any country, technology plays very vital roles in acquiring a sound technological development in land administration. Traditional approaches to the land administration in the time past, has resulted in the delay of the processes of land titling and registration. The innovative technology brought by geographic information system (GIS), land information system (LIS) and cadastral information system (CIS) has been playing a leading role in the development of cadastral and land administration in Nigeria. The need to develop a web linked with the network of the processes in the land registration arises from the fact that people relationship to land has a very dynamic nature. The delay in time and process of land registration couple with the corruption in land related activities has called for the urgent intervention of all the stakeholders in land administration. In this study, an online network of the processes involved in the land registration was done having investigated the quickest way to solve the problem. A web was designed so that an applicants can check the status of their application online. A more secured cadastral plan must be submitted as one of the documents needed for the application for certificate, the (C of O). The benefits of this system to all stakeholders in land administration in the study area were also discussed.

 Assessment And Determination Of Spatial Distribution Pattern Of Filling Stations In Akure Metropolis, Ondo State Nigeria

 Tukka, A .A. Odunaiya, A. K.

 2018

This study aimed at Assessing and Determination of Spatial Distribution pattern of Filling Stations in Akure Metropolis, Ondo State Nigeria. Department of Petroleum Resources (DPR) stipulated that ‘distance from the edge of the road to any nearest pump should not be less than 15m and less than 400 meters to the next petrol filling station and not be located less than 100 meters from school, hospital, theatres, clinics and other public and semi-public buildings. Meanwhile, in line with the objectives of this study, the Global Positioning System (GPS) instrument was used to acquire spatial and attribute data where queries employing proximity and buffering analysis was performed using ArcGIS 10.3 software respectively. The Z ratio analytical technique was used to examine the conformity of petrol filling stations to the required distance of 400m and 15m from each other and from the road respectively as stipulated by DPR amendment decree 37 of 1997. Findings from the Z ratio analysis at 66 degree of freedom and 95% confidence level reveals that 32(57%) conform to the required distance of 400m apart, 25(40%) conformed to the required distance of 15m from the existing road, 95.5% conformed to the required distance of 100m from existing school and 100% conformed to the required distance of 100m from the existing healthcare facility. there is a general an indication that the distribution of Filling stations in Akure metropolis is tending towards a clustered pattern which automatically translates into high level vulnerability to potential hazards associated with each utility. Thus, recommended is hereby made for adoption of this work by the regulatory agency DPR, as an A-prior data to improve their capacity in enforcing the compliance of petrol filling stations with laid down regulations.

 Power Line Electrification Hazard Mapping: A Case Study Of Federal University Of Technology, Akure, Ondo State

 Odunaiya, K. , Ipadeola, O. , And Tukka, A. A

 2018

Electrical Power remain one of the driving forces of any meaningful economic development, but many a times, losses are encountered when disasters befalls as a result of non-compliance to the standard setback and height clearance provisions of the Town and Country Planning Law CAP 123; the building and subdivision regulations, 1984 of Ondo state for construction of this important infrastructure even in the most prestigious academic environs. Utilizing the 3-D data gathering surveying traverse method and GIS analytical software within the 577.97 hectares of Land of Federal University of Technology Akure, this research was able to cover a total of 241 Medium Tension (MT) poles, 28 Medium Tension/ Low Tension, 365 Low Tension (LT) poles and 6 Transformer. This finding revealed from analysis that with respect to the MT poles just 48%, 16% and 36% of the residential, institutional and educational buildings respectively and for the LT poles just 36.1%, 30.5% and 33.3% of the residential, institutional and educational buildings respectively were in compliance with the guidelines and laws of Ondo state. Analysis have shown that the compliance level is discouraging and it was recommended that adequate measures must be put in place by all relevant authorities of the University and the Power Holding Companies of Nigeria (PHCN) to forestall possible recurrence of imminent danger therefrom.

 Comparative Analysis Of Positional Results Of Post Processed GPS Survey Data Using Three Trimble Software Packages

 1Tukka, A. A., 2Dodo, J. D. And 3Ariyo, T. O.

 2012

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.
