Flood is one of the most devastating natural hazards which lead to the loss of lives, properties and resources. It has therefore become important to create easily read, rapidly accessible flood hazard map, which will prioritize the mitigation effects. This study addresses the need for an efficient and cost-effective methodology for preparing flood hazard maps in Ghana, particularly those region...

The popularity of Internet technology has brought about some fundamental changes in the field of GIS. Internet GIS is emerging as a new technology to access, process, and disseminate spatial information over the Internet. Internet GIS cover a much wider audience than the traditional GIS. This raises many issues that are distinct from traditional desktop GIS, such as easy access, webcompatible u...

Ž . Environmental planning takes advantage of geographic information systems GIS to manage geographic data. GIS are, however, tools which require a great deal of training and programming expertise and, furthermore, have little support for decision makers during their planning activities. This paper presents WOrkflOw-based spatial Decision Support System Ž . WOODSS — a software developed at the ...

One of the challenges according to Dangermond (1999) and Tomlinson (2000) for GIS units in the 21st century is to be able to manage themselves successfully in order to deliver the right product at the right time to the right customer. Tomlinson (2000) also indicated that there will be several management tools available to assist GIS units to enable them to manage themselves successfully. This p...

GIS has emerged as an elitist, anti-democratic technology by virtue of its technological complexity and cost. The question of democratizing this technology has been addressed in the GIS and Society literature. This paper addresses the thorny issue of uneven access to GIS and the associated social power it confers. Following the principle that effective access to information leads to better gove...

Geographic Information Systems (GIS) are used to store, manipulate and visualize both spatial and non-spatial data. Because of their data manipulating capabilities, GIS have been linked to different simulation models in different research areas and are commonly used for both surface and ground water modeling. Unfortunately this has been done mainly with proprietary GIS which are expensive and w...

Cocoa occupies 6 million hectares in humid coastal West Africa where 70% of the world supply is grown, 90% of which is produced on 2 million family farms of 2 hectares or less. Here, at least 16 million people depend on cocoa but earn only $100/person/year from the crop. There is need to optimize the farming system, minimize the environmental impact of technologies, and improve socio-economic d...

Geographic Information System (GIS) has long been essential tool for governments, environmental institutions, military and others who depend on geographic information. GIS combines layers of data about a location to create a fuller and more accurate picture of that location. These data are obtained from different sources in different formats, datum and coordinate systems. The problem of traditi...
