Item DECISION MAKING IN SURVEYING AND GEOINFORMATICS(Faculty of Environmental Sciences, University of Ilorin Kwara State Nigeria, 2019) Babalola, A.; Ipadeola, A.O.; Issa, B.S.One of the most important decisions that a surveyor has to make before embarking on a given surveying project is the selection of the instrument. Where there are number of choices, a decision by way of selection has to be made. The selection can be based on a number of criteria, for instance, accuracy, cost, user friendly, size of project, user knowledge and experience, project type and duration. The need to have the best equipment for the right job cannot be overemphasized. This requires that the surveyor should select the equipment to be used in an objective way, taking into cognizance all factors and their priorities. The aim of this paper is to demonstrate the use of the Analytical Hierarchy Process (AHP) as a form of decision-making methodology in the selection of equipment for a surveying project. Priority weights for each factor controlling the choice are also determined. 3 instruments were considered for selection – Total station, DGPS and theodolite and 7 elements used in the instrument selection - accuracy, cost, user friendly, size of project, experience/ knowledge, project type and duration. The accuracy of the equipment appears to be the element with the highest importance. While experience and knowledge accounted for the next element on the level of importance. The element with the least importance user friendly element.Item GEOSPATIAL ANALYSIS OF THE LAND USE AND LAND COVER CHANGES OF ILORIN METROPOLIS BETWEEN 2000 AND 2017 USING REMOTE SENSING AND GIS TECHNIQUES(Department of Surveying and Geoinformatics, Faculty of Environmental Sciences, University of Ilorin, Ilorin Kwara State Nigeria, 2018) Ipadeola, A.O.; Odunaiya, A.K.; Tella, A.K.; Issa, B.S.; Yusuf, A.; Olabode, T.B.The paper focuses on geospatial analysis of the land use and land cover pattern in Ilorin metropolis using Remote Sensing and Geographic Information System technique (GIS). Rapid land use change has taken place in many developing cities of Nigeria including Ilorin over the past decades. Information on the constant change in land use pattern for Ilorin metropolis is of importance because the city is experiencing rapid land use/cover changes and because land use/cover pattern information is indispensable for sustainable rural-urban land use planning and development. Landsat 7 and 8 images of Ilorin metropolis at three epochs of the years 2000, 2010 and 2017 were used. Environment for visualizing images (ENVI) and ArcGIS software were used for the image classification, image enhancement and further processing, analysis and land use map production. The Land consumption rate and land absorption coefficient pattern were analyzed. The results show that water body increased significantly from 0.474%, 0.474ha area in 2000 to 0.589% in 2010 and experienced even a greater increase in 2017 with 0.731% with an of 7.914ha of the total class. Built-up land increased massively from 26.901%, 420.534ha area occupied in 2000 to 511.770ha, 39.439% area in 2010 and showed a slight drop between 2010 and 2017 to 501.822ha representing 46.333% of the total class. In 2000, vegetation occupies 36.254%, 566.748ha but experienced an increase of 9.33ha area and occupied the highest class with 42.956% in 2010 but showed a massive decrease in 2017 to 358.761ha and 33.124% of the total class. Bare land showed a consistent decrease from 2000 with 568.593ha, 36.372% to 220.806ha, 17.016% in 2010 to 214.581ha, and 19.812% area of the total class in 2017. The study reveals increase in population of the metropolis, steady but increasing trend in built up land and reduction in vegetation. If adequate measures are not put in place, there may be a great measure of loss of naturally vegetated area in Ilorin metropolis, which is mainly because of urban growth and expansion, farming and gully erosion. This paper also confirms the convenience, accuracy and reliability of GIS and Remote Sensing techniques for geospatial analysis of landuse and land cover changes. It is recommended that the information from the results of this work should be use to optimally, effectively plan, and manage the study areaItem SELF-RELIANCE AND COMMUNITY INITIATIVE: FOCUS ON COMMUNITY DEVELOPMENT ASSOCIATIONS IN IDO LOCAL GOVERNMENT AREA, OYO STATE(Faculty of Environmental Sciences, University of Ilorin Kwara State Nigeria, 2018) Ola, A.B.; Adewale, Y.Y.; Bako, A.I.; Issa, B.S.The observed inadequacy in infrastructural facilities in the rural areas of Nigeria has triggered the formation of community development associations (CDAS) to engage in infrastructural development in their respective communities. The contribution of these (CDAS) to the provision of infrastructural facilities in the rural areas of Ido local government area of Oyo state was examined in this paper. Cross-sectional survey research design was adopted for the study. Structured questionnaire was used to obtain information from five purposively selected (CDAS) leaders. the study revealed that water projects and road rehabilitation were the major infrastructural projects executed by all (100%) and 60% of the (CDAS) respectively. The (CDAS) secured funds through compulsory levies paid by members (100%), financial assistance from members of the communities in diaspora (40%), philanthropists (40%) and voluntary donations by community members (20%). Infrastructural facilities provided by the associations enjoyed adequate patronage from community members (100%). There was positive perception of the existence and relevance of the (CDAS) in their respective communities by the residents. inadequate funds (60%); lack of financial assistance from government (100%); and non-payment of compulsory levies by some members (40%) were the challenges facing the (CDAS). the paper posits that for any rural infrastructural development efforts of the government to be successful and sustainable, involvement of the rural people (target users) through their (CDAS) is desirable.Item Self-Reliance and Community Initiative: Focus on Community Development Associations in Ido Local Government Area, Oyo State.(Published by Faculty of Environmental Sciences, University of Ilorin, Ilorin., 2018-05-17) Ola, A.B.; Adewale, Y.Y.; Bako, A.I.; Issa, B.S.The observed inadequacy in infrastructural facilities in the rural areas of Nigeria has triggered the formation of community development associations (CDAS) to engage in infrastructural development in their respective communities.
