Both geographic information systems (GIS) and network analysis are burgeoning fields, characterised by rapid methodological and scientific advances in recent years. A geographic information system (GIS) is a digital computer application designed for the capture, storage, manipulation, analysis and display of geographic information. Geographic location is the element that distinguishes geographi...

To get a more convenience work in forest application, GIS and information system is used in forestry. GIS technology is used to build an informational management system of forest disease. For the practical requirement, the system is implemented by PDA which works outside to help completing the data collection. The major function of the system is input and output of the forest disease data and p...

The provision of dynamic mapping and spatial analysis over the Internet poses challenges both in terms of technology but also bandwidth and performance. d-cypha has met this challenge with the implementation of a three-tier technology solution called d-cyphaMap currently being offered as an ASP service in New Zealand. Underpinned by Oracle Server, the d-cyphaMap solution also incorporates softw...

Three-dimensional (3D) GIS is gaining more and more acceptance among both scientists and the general public. Though powerful in data visualization, 3D GIS is comparatively weak in geospatial analysis. In order to enhance 3D GIS’s analysis capability, we present an approach for integrating geospatial processing services into 3D GIS. The architecture of our approach contains four layers which are...

The advancement of Internet technologies and geographical information systems (GIS) have opened up new opportunities for the application of Internet-based GIS in the context of information and knowledge management. Based on the observation that almost every type of information resource has some geographical relationship this paper introduces how GIS can be used as search components in informati...

The inclusion of error handling capabilities within geographical information systems (GIS) is seen by many as crucial to the future commercial and legal stability of the technology. This thesis describes the analysis, design, implementation and use of a GIS able to handle both geographical information (GI) and the error associated with that GI. The first stage of this process is the development...

Four critical computing issues r...

Increasingly sophisticated technologies, such as On-Line Analytical Processing (OLAP) and Geospatial Information Systems (GIS), are being leveraged for conducting community health assessments (CHA). Little is known about the usability of OLAP and GIS interfaces with respect to CHA. We conducted an iterative usability evaluation of the Spatial OLAP Visualization and Analysis Tool (SOVAT), a soft...

As a new development based on GIS and distributed computing, Distributed GIS (DGIS) was introduced and propelled by both the demands for GIS in a distributed environment and the advancements of computing technologies. Demanding for new geospatial applications presents new challenges for DGIS, and the solution to overcome the challenges in turn leads to the advancement of DGIS. This article exam...

This paper presents an overview of GIS certificate programs available through colleges and universities in the United States and Canada. It is argued that by presenting a structured sequence of coursework, GIS certificate programs have begun to address the varied educational goals of both traditional students and non-degree professionals. A survey of certificate programs listed on the World Wid...
