Purpose – The purpose of this paper is to provide an overview of free and open source (FOSS) geographic information system (GIS) software within the broader contexts of the open source software movement and developments in GIS, and pose the question of whether libraries and academic departments should consider adopting FOSS GIS. Design/methodology/approach – The process of creating a basic them...

One of the important stages in the implementation of a GIS is referred to preparation of data to be entered to the system. To produce spatial data for entering to GIS using photogrammetric techniques, common and current method is to utilize photogrammetric and GIS systems individually (off-line procedure). Preparing spatial data on the basis of the mentioned method has a lot of problems, such a...

This paper makes the case that the time is right for certification and/or accreditation in GIS. The paper begins with a brief history of the debate, and details current trends in the field of GIS that are driving current initiatives in GIS certification and accreditation. The two major driving factors are major growth of the GIS profession, and initiatives coming from the Surveying community. I...

What this paper tends to address are followings. (1) A notable common characteristic of many GIS applications we ever might ignore is that the ability of analysis is not primarily provided by GIS itself, GIS generally plays roles of data management and virtual environment construction, and it is the users of GIS software that achieve that intelligencerequired process of problem solving. That is...

The use of geographic information system (GIS) technology allows public health practitioners to explore disparities in health, analyze disease outbreaks, and prioritize the use of limited resources for improving population health. Nursing students benefit from use of World Wide Web GIS resources as they develop knowledge and skill in assessing population health and planning interventions. This ...

The three-year Municipal Infrastructure Investment Planning (MIIP) project is currently investigating investment planning and strategic asset management. The project proposes using geographic information systems (GIS) as the framework for decision support tools for municipal infrastructure managers, and more specifically, as tools to assist them to prioritize infrastructure maintenance and capi...

ABSTRACT This paper describes the Active Response GIS (AR/GIS) for resource planning and land­ allocation deliberation. AR/GIS is an integrated system which combines GIS and electronic meeting software. This combination provides the voting, information organization, and brainstorming of an electronic meeting system, and supports interaction with geographic data sets. The AR/GIS system can impro...
