DEFINITION Network GIS Performance (NGP) refers to the level of Quality of Services (QoS) of a Network GIS. NGP includes both the efficient use of Network GIS resources (CPU, memory, massive storage, geospatial data and geospatial services) and the perception of speed of a Network GIS [1]. Network GIS is a GIS where the geospatial data and geospatial processing are distributed across a computer...

A global information system (GIS) connects companies in various countries. Although GIS professionals have produced many facilities for connectivity, only a few have developed a comprehensive GIS model to overcome the obstacles. Complexities, ambiguity as well as other risks are among GIS development difficulties. To develop an efficient and effective decision-making process, critical performan...

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...

GIS eased into geography without much discord until the 1990s, when a flurry of commentaries about the relative merits of GIS made their way into a number of geographic journals. The ensuing decade was marked by varying degrees of friction between GIS practitioners and their critics in human geography. Despite the methodological chasm between the two groups, little discussion of the implication...

It is argued that a corporate GIS is the lowest level in a hierarchy of spatial data infrastructures (SDIs) worldwide. Therefore, SDI development can benefit from a good understanding of the nature and dynamics of development of a corporate GIS. To facilitate this cross-fertilisation, existing definitions of GIS are briefly reviewed in the context of the organisational setting of a corporate GI...

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...
