The GIS literature abounds with strategies to guide the development of a corporate GIS as a single project but lacks discussion on the long term management of the GIS. This paper documents a recent study into GIS development in a state department over an 18-year period. It applies the productional perspective of GIS to model long term GIS development diagrammatically and identiŽ es Ž ve pattern...

The Open GIS Consortium (OGC) has proposed a standard for the software architecture of geographic information systems (GIS) in order to enable interoperability among different GIS products. The so-called Abstract Model does not support spatial constraints yet, although most of the later proposals of GIS conceptual data models already do. This paper presents an extension of OGC’s Abstract Model ...

Geographic Information Systems (GIS) have become a fact of our life as they are being used by more people and organizations for more complex decision problems than ever before. The use of GIS can achieve valuable benefits for individuals, organizations and society; however, the achievement of these benefits depends on the success of GIS. While information systems (IS) success models have receiv...

Nowadays, there are many attempts to establish object-oriented GIS in some software However, they are not accordant to object-oriented concept whole and systematically in the whole course from the process of cognizing and abstracting geographical space to the process of defining and describing GIS data model then to the process of analyzing and designing GIS. Especially, the research on common ...

The national spatial data infrastructure (NSDI) and GIS maturity of user organisations are mutually dependent. Only when the GIS maturity of user organisations is at a high level can they direct their needs to the development of an NSDI and the benefits of the NSDI come true to their full extent. To raise their GIS maturity to a level where user organisations can both utilise spatial data compr...

This paper discusses the integration of a geographic information system (GIS) and moving objects in surveillance videos (“moving objects” hereinafter) by using motion detection, spatial mapping, and fusion representation techniques. This integration aims to overcome the limitations of conventional video surveillance systems, such as low efficiency in video searching, redundancy in video data tr...

The security model proposed for the Geographic Information Systems (GIS) is a data, which is capable of visualizing technology and has the capability to apprehend, cache, verify, amalgamate, engineer and exhibit data with the help of digitized maps. It has enormous applications in the field of engineering, business management process, communication both in the private and public regions. A GIS ...

a r t i c l e i n f o Keywords: BIM GIS FM Integration Surface model BG-ETL In this study, we propose software architecture for the effective integration of building information modeling (BIM) into a geographic information system (GIS)-based facilities management (FM) system. This requires the acquisition of data from various sources followed by the transformation of these data into an appropri...

This study aims to delineate groundwater potential zones in Tana Righu. Multiple thematic maps were prepared using RS and GIS techniques was assigned suitable weights on the Saaty’s scale. The of then normalized AHP technique. Ultimately, these integrated with a weighted overlay technique GIS. results showed that about 42% area has “moderate” potential; 35.86% “high” 28,82% ”low” potential. 3.5...
