Control Position Fix Using Single Frequency Global Positioning System Receiver Technique-A Case Study
This research investigated the use of Single frequency GPS for position fix by differential GPS technique. Ten controls on the UMaT campus were coordinated by Precise Traversing and GPS techniques. The results shows average standard deviations for morning, afternoon and evening observations for the planimetric coordinates of receivers oriented to the north and not to the north From the analysis of the results obtained, the morning and evening observations with GPS receiver oriented to the north direction produced better accuracy.

Assessing and Modeling Land Cover Changes Using Remote Sensing and GIS in the Ejisu-Juaben
This study was conducted to identify the various causes and areas prevalent to changes in the Ejisu-Juaben using remote sensing and GIS techniques. The project used the unsupervised classification in assessing and monitoring the various changes. The result indicated that the change due to increase in population and agricultural activities are significant; thus built up areas have increased from 20.7378 km2 to 53.9771 km2 and agriculture from 295.11 6 km2 to 401.753 km2 from 2004 to 2007. The rate of the change should be assessed and the information generated should be used for better planning of the municipality.

Mapping Malaria Incidence Using GIS for Health Information Management
In this research, a database of malaria incidence and the geographical information representing the boundaries as well as the centre of the administrative units of the Western Region of Ghana were built using cartographic and GIS techniques. When the incidence rates of malaria were examined spatially, some areas were found to be malaria endemic whiles others were malaria season. This study can be considered as a pilot application for the distribution of malaria incidence rate on maps to facilitate control program against the disease and to examine the environmental factors causing the disease spatially.

Modelling Flood Prone Areas Using GIS: A Case Study of the Ga and Accra Metropolitan Districts
In this study, GIS was adopted to predict flood prone areas in the Ga and Accra districts. DEM together with Distance Allocation to rivers is combined using Weighted Sum to produce flood prone maps within the Ga and Accra Metropolitan districts. To do this, the contour map of the area was converted to DEM in a rasta environment. The DEM map produced and distance allocation to river map were weighted to produce a flood risk map which showed that areas like Weija, Nsakyina, Odumase, Manhean, and Kolokohwe are flood prone.

Pit Wall Monitoring at Ghana Bauxite Company Limited
This study established that monitoring of the slopes of surface mines can prevent loss of life, equipment, production and possibly the mine. Overviews of slope monitoring requirements, from the survey points of view, as well as the types of equipment and instrumentation that are available were determined. It concluded that conventional survey instrumentation will continue to have their place in slope monitoring.

The Use of GIS to Study the Spatial Variations of Diseases: A Case of Western Region, Ghana
In this research, a database of disease statistics and the geographical information representing the boundaries as well as the centre of the administrative units of the Western Region of Ghana were built using cartographic and GIS techniques-choropleth mapping to examine the spatial distribution of the selected diseases.

Assessment of the Quality of Spatial Data: A Review.
This research explored data quality measures that may eliminate any liability lawsuits against data developers and data users. It also assessed the future of Spatial Data Quality and the role of Spatial Data Authority, Ghana (SPADAG), may play.

Land-use/land-cover Mapping using Remote Sensing for Urban Development-A Case Study of Tarkwa and its Environs.
In this research, a study was carried out in the Tarkwa municipality of the Western Region of Ghana to detect land use/land cover changes over a period of 17 years (1990-2007) using remote sensing and to assess its implications for the management of future urban development. The fundamental materials and data types used for the assessment consisted of temporal Landsat satellite images of a 20 km radius of Tarkwa for the years 1990, 2000 and 2007 as well as 162 ground reference points.

Site Selection for Waste Disposal using GIS.
This study investigated most suitable site, greater than one hectare (1 ha) for constructing a waste disposal site for the Akosombo Community, in the Eastern Region of Ghana using GIS application. To achieve this, Spatial Multi-Criteria Evaluation (SMCE) window of ILWIS Software was used to perform Multi-Criteria Evaluation in a spatial context. The input data was a number of raster maps of Akosombo known as criteria. These criteria were grouped, standardised and weighted and an output map generated indicating the extent to which criteria are met. The output map indicated suitable areas with a total area of suitability being 34.42 ha.

Predicting the Yield of Crops using GIS/GPS Integration.
This research discussed the prediction of crop yield using GIS/GPS integration. The area of the study was the Benso Oil Palm plantation Ltd. in Takoradi. Data on yield and selected variables, namely; soil organic matter content, soil potassium content and amount of fertilizer applied, for fifty-five blocks were collected to predict the yield of the oil palm. Global Positioning and Geographical Information Systems were used in the mapping of the study area to depict the variability of yield and the spatial factors.

Mapping Swollen Shoot Disease using GIS at the Afosu Plantation of Cocoa Research Institute (CRIG), Tafo.
This research explored the possibility of using GIS to map swollen shoot disease in a cocoa farm and to predict the most prevalent areas of the farm affected by the disease in order to isolate the area for treatment. In this study, a portion of the farm was demarcated and a grid was put on it. The coordinates of the grid nodes were recorded with their corresponding number of infested trees and a spatial distribution map was developed for the prediction of the disease in the farm.

Assessing the Spatial Distribution of Arsenic from Goldmine for Environmental Management at Obuasi, Ghana.
In this research, geostatistics were applied to study the hazard posed by arsenic in the area. The ordinary kriging estimates of arsenic were mapped using soil samples and indicator kriging applied to characterize the hazard posed by arsenic concentration at a threshold value of 20 ppm in the study area. These maps provide a decision support tool to define the areas where remedial action is needed in the light of the risks to humans and the ecosystems.

Determination of a Mathematical Model between Global and Cartesian Coordinate Systems.
In this research, the latitudes and longitudes of selected stations with known Cartesian coordinates were determined using a hand-held GPS. Statistical analyses were conducted to establish a correlation between the Global and the Cartesian coordinates of the selected stations and a mathematical model generated to represent the results. The results yielded a remarkable deterministic coefficient of 92% between the Global and Cartesian coordinate systems.
