A Comparison of Depth Interpolation by Using GIS & Neural Networks
Depth measurement is Considered as a first goal in hydrographic survey, it depends on different techniques and instruments, it’s most costly procedures. However; some mathematical models are used for condensing depths with a relatively low cost. Artificial neural networks appears and in many applications used to solve real-world forecasting, classification and function approximation problems. It is fast, intelligent and easy to use Neuro Intelligence supports a...
Assessing The Accuracy Of Global Population Distribution Datasets For Maternal And Perinatal Health Applications
ABSTRACTGlobal 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 heterogen...
Land Use And Land Cover Changes Detection In Abakilikimetropolis And Its Environs From 1986 To 2014 Using Remote Sensing And Geographic Information System.
ABSTRACTThis project examines the use of GIS and Remote Sensing in mapping Land Use LandCover in Abakiliki between 1986 and 2014 so as to detect the changes that has taken placebetween these periods. Subsequently, an attempt was made at overlaying the observed landuse land cover in those epoch time. In achieving this, Land Consumption Rate and LandAbsorption Coefficient were introduced to aid in the quantitative assessment of the change.The result of the work shows rapid growths in built-up l...
Site Suitability Analysis For Solid Waste Disposal In Enugu Urban Using Remote Sensing And Geographic Information System
ABSTRACTIdentifying solid waste disposal sites and appropriately managing them is a big task to manydeveloping countries. This is a critical problem in Enugu urban in particular. The existing sitein Enugu urban is not sufficient in its capacity and it is damaging the environment due to itslocation, and the type of waste dumped, while the surrounding area is being irrigated. Due tothe expansion and urbanization developments in Enugu State, it badly needs to developcontrolled solid waste dumpin...
Optmisation Of Primary Heath Care Facility Location, Case Of Gweru District.
ABSTRACTAs 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 o...
Solid Waste Collection Management Information System For Gweru City Council
AbstractSolid 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 ...
Location Theory Based Bio-energy Systems planning in site optimisation modelling – Manicaland (Zimbabwe
ABSTRACTIn as much as decision makers increasingly are turning to Geographical Information Systems toassist them with solving complex spatial problems, these systems on their own do not adequatelysupport decision making because they are lacking in analytical modelling capabilities, do noteasily accommodate variations in either the context or the process of spatial decision making.One response to these shortcomings is the development of spatial optimisation modellingtechniques which are explic...
Models For Flooding And Erosion Control In Parts Of Nigeria
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...
Modelling Traffic Congestion Using Analytic Hierarchy Process In A Geomatics Environment, A Case Of Lagos State
1.0 BACKGROUNDMany 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 forma...
The Use Of Object Oriented Image Analysis Automatic Extraction Of Unpaved Roads In Updating Road Maps: A Lesson For The Department Of The Surveyor General
AbstractThis 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 an...
Examining the relationship between road traffic accidents and the environmental factors using spatial statistics
AbstractThis 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 hotspots ...

A Grounded Theory Approach To The Investigation Of Cadastral Activities And Processes Of Gweru Municipality
AbstractThis 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 la...
The Method Of Simulated Annealing For The Optimal Adjustment Of The Nigerian Horizontal Geodetic Network
ABSTRACTThe Horizontal Geodetic Network of Nigeria is made up of terrestrially arranged chains oftriangles augmented by precise traverses. The work on the network began early 19th centurybut by 1930 the work was discarded and a re-observation of the network was carried out tothe highest possible accuracy then, enhanced with high order geodimeter traverses whichlinked to other neighboring African networks.The full network consists of 515 stations, with 2411 observations which comprise 2197 ang...
Web Based City Engineering Services Fault Reporting System: A Case Study Of Gweru City Council Engineering Department Chapter 3: Methodology
ABSTRACTLocated 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 vol...
