ABSTRACT Global population distribution datasets have been used in a lot of studies and research programmes including public health research due to their availability and large scale geographical coverage. Their increasing application in maternal and perinatal studies has increased the implications of the data extracted from the datasets. The newly developed SDGs with very high expectations in terms of deliverables in the health care sector require high quality data which reveals the heteroge...
ABSTRACT This project examines the use of GIS and Remote Sensing in mapping Land Use Land Cover in Abakiliki between 1986 and 2014 so as to detect the changes that has taken place between these periods. Subsequently, an attempt was made at overlaying the observed land use land cover in those epoch time. In achieving this, Land Consumption Rate and Land Absorption Coefficient were introduced to aid in the quantitative assessment of the change. The result of the work shows rapid growths in buil...
ABSTRACT Identifying solid waste disposal sites and appropriately managing them is a big task to many developing countries. This is a critical problem in Enugu urban in particular. The existing site in Enugu urban is not sufficient in its capacity and it is damaging the environment due to its location, and the type of waste dumped, while the surrounding area is being irrigated. Due to the expansion and urbanization developments in Enugu State, it badly needs to develop controlled solid waste ...
ABSTRACT As access to health care is a human right in Zimbabwe it is expected that primary health facilities should be optimally located to serve demand. It is therefore a challenge for the government and policy makers to provide primary health facilities which are optimally located to serve demand conveniently. This paper highlights a GIS method for optimising location of primary health care facilities. The study area is Gweru district in Zimbabwe. Using location allocation models in ArcGIS ...
Abstract Solid waste alludes to all materials that are not prime items, for which the individual creating the material has no further use in terms of his or her own motivations for generation and utilization. In developing countries, Zimbabwe included, municipal authorities rely on poor methods and techniques in waste collection administration which are subjective and tend to increase operational costs of solid waste collection activities. Instead of maintaining vibrant information management...
ABSTRACT In as much as decision makers increasingly are turning to Geographical Information Systems to assist them with solving complex spatial problems, these systems on their own do not adequately support decision making because they are lacking in analytical modelling capabilities, do not easily accommodate variations in either the context or the process of spatial decision making. One response to these shortcomings is the development of spatial optimisation modelling techniques which are ...
ABSTRACT Flooding and erosion phenomenon is a major environmental problem prevalent in the rainforest region of Nigeria. The need to develop appropriate models to control the menace of the phenomenon is informed by the high demand for land and the increasing incidents of flooding and erosion in some parts of the country. Whatever model is to be adopted, its effectiveness depends on the contributions from geodetic measurement data. Once relevant data from geodetic and other sources have been ...
1.0 BACKGROUND Many of the metropolitan traffic management control centres established in 1970's and 1980's in the Western and Asian countries have been replaced by large wall-mounted maps with Geospatial Information Systems (GIS) displays. This is done in order to achieve optimal transportation systems. The capability of GIS to map and define the geometric relationship between spatial entities (topology), overlay separate entities of the same theme, and to handle data of different formats ha...
Abstract This paper exhibits a method for extraction of unpaved roads from high resolution Pleiadis satellite imagery using Object Oriented Image Analysis (OOIA). The study area is Woodlands in Gweru Zimbabwe. Using ENVI EX, a rule based classification was performed. Classification rules were made from unpaved roads properties, by utilizing combination between unique multispectral bands, principal components and also utilizing combination of geometric attributes like width, length, neighbor a...
Abstract This research presents an approach to examine the relationship between road traffic accidents and the environmental factors using spatial statistics. Road accident data for this research study was acquired from Leeds City Council database for the years 2009 to 2016.Other used datasets were obtained from OSM and DivaGis websites. To examine spatial patterns of road traffic accidents in the city of Leeds, network kernel density estimation was used to determine the road accident hotspot...

Abstract This paper explores the power of Constructivist grounded theory methodology to discover the theory of the Gweru Cadastral processes and activities. The researcher used the tools and techniques of constructivist grounded theory to mine rich data at Gweru council which he then performed data analysis to yield analytic categories. The researcher then used these analytic categories to write the Gweru cadastral processes theory which he then compared with the theory within the domain of l...
ABSTRACT The Horizontal Geodetic Network of Nigeria is made up of terrestrially arranged chains of triangles augmented by precise traverses. The work on the network began early 19th century but by 1930 the work was discarded and a re-observation of the network was carried out to the highest possible accuracy then, enhanced with high order geodimeter traverses which linked to other neighboring African networks. The full network consists of 515 stations, with 2411 observations which comprise 21...
ABSTRACT Located in and forming part of their communities, councils are ideally positioned to search out the fine approaches to meeting local needs. Accountable for delivering an estimated eighty per cent (Andrew, et al., 2013) of public sector transactions of their areas, local authorities have a particular responsibility to design their services in probably the most accessible, monetary and ‘user-friendly’ manner. A critical function is to work intently with other public, private and vo...
ABSTRACT Needs for spatial data are increasing due to the different uses it can be put to. Due to the progress in digitalization, the volumes of data in various fields are accumulating quickly at an unprecedented speed. Different types of spatial resources come from different units but they may be integrated effectively through SDI development so that users can easily obtain and apply the shared resources. Spatial Data Infrastructures (SDIs) enable access, sharing and propagation of spatial d...
