Geographical Bioinformatics Systems (GBS) represent the marriage between two distinct and well established fields, GIS & Bioinformatics. Bioinformatics refer to the use of computers to handle biological information—that is, the use computers to store, compare, retrieve, analyze and predict the composition or structure of biomolecules. On the other hand, the term Geographic Information Systems (...

Although Geographic Information Systems (GIS) have been recognised as the most advanced technology for the management of geospatial information, they are still unable to efficiently manage the temporal dimension. Originally this problem affected only the study and analysis of highly dynamic phenomena. Today’s expansion of GIS technology, the ease to acquire and store geospatial data and the inc...

The changing trends in information technology have greatly influenced the role of GIS in spatial data management, analysis, processing and presentation. It has evolved from the conventional cartography and image processing to advanced 3D visualization and dynamic graphics tools. Due to this evolving nature of GIS, it has found wide applications in a number of diverse fields. Geophysical explora...

The notion of “real world” geographic information systems (GIS) technology can be examined through reviewing how one of Brazil’s largest non-governmental organizations (NGOs), Fundação SOS Mata Atlântica, has evolved in an iterative process with the development and use of GIS technology. Examining the actual ways in which GIS is incorporated into the activities and actions of NGOs, such as Fund...

Geographical Information System (GIS) is a hot topic. There is now a textbook and a journal devoted to the subject (Burrough, 1986; Coppock and Anderson, 1986) and it seems one can attend a conference on the subject practically any week. Although computer processing has been applied to geographical problems for more than a quarter of a century, it appears that there must be something different ...

An evaluation was conducted on a web-based e-learning system designed to facilitate integration of Geographical Information Systems (GIS) into the Civil Engineering curriculum. The principal goals of the evaluation were to determine the overall effectiveness of the system and to better understand underlying learning processes. Data were collected from 80 students who participated in a computer ...

One of the fundamental issues of geographical information science is to design GIS interfaces and functionalities in a way that is easy to understand, teach, and use. Unfortunately, current geographical information systems (including ArcGIS) remains very difficult to use as spatial analysis tools, because they organize and expose functionalities according to GIS data structures and processing a...

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...

Recently, Geographical Information System (GIS) has emerged as an innovative and important component of many projects in public health and epidemiology. One of the most useful functions of GIS in epidemiology continues to be its utility in basic mapping. GIS may also involve more sophisticated spatial analysis of disease occurrence and contributing environmental factors. Depending on the quanti...

In this paper we present a novel Point-based pattern analysis for predicting Cassiterite (tin-ore) as a secondary mineral deposit in the Plateau Younger Granite Region of Nigeria (PYGR) using statistics, spatial analysis and machine learning techniques. Existing mining data points collected from field survey in the PYGR and the geological map of the region were digitized and converted into shap...
