The different identities of GIS and GIS diffusion

The di erent identities of GIS and GIS di usion TAI

GIS managers traditionally consider three perspectives of the nature of GIS when introducing GIS into an organization. When the GIS is developed to address focused and well de® ned problems of the organization, these perspectives adequately describe the changing identities of GIS in the study of its di€ usion. However when the GIS is developed to address strategic, but vaguely de® ned problems,...

The “marine Gis” – Dynamic Gis in Action

The sea moves: the land usually stays still. It is not surprising that the underlying structure of a land-based GIS is rarely appropriate for marine applications. Add the third spatial dimension and it is clear that an attempt to simulate the sea requires a major overhaul of the appropriate algorithms and data structures. It has seemed obvious to us for some time that spatial data structures ne...

Dielectric Strength of Different Gases in GIS

SF6 is a gas with excellent dielectric properties and is commonly used in gas-insulated equipment. However it has the high global warming potential. Thus, the development of new gases or gas mixtures for GIS, GIL is strongly desired. For dimensioning the gas insulated systems the support insulators (spacers) are of special interest. Contaminations on the insulator surface can cause field distor...

Participatory Gis a People's Gis?

Recent years have witnessed a burgeoning of applications of GIS which grant legitimacy to indigenous geographical knowledge as well as to ‘offi cial’ spatial data. By incorporating various forms of community participation these newer framings of Geographical Information Systems as ‘Participatory GIS’ (PGIS) offer a response to the critiques of GIS which were prevalent in the 1990s. This paper r...
