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...

Geographical Information Systems (GIS) and Image Processing Systems are usually based on classical logic and set theory. This fact pass in case of some GIS elements because of presence of many uncertainties in the nature. Hence, these GIS elements can not be based on classical model at all time. Constantly growing demands on utilization of GISs require extension of area of their usage in the wa...

The truthfulness and understandability of information is dependent upon the way it is presented. It is admitted now that almost 85% of the data in human brain is related to geography and we continuously keep upgrading urban information in our brain consciously or unconsciously. This information, if updated frequently, affects most of the decisions made in our life. Maps are considered an easy a...

To improve the spatial retrieving by means of Geographical Information Systems (GIS), a distributed GIS-Application has been designed. This application is mainly focused on making spatial analysis, throughout Spatial Analyzer Module (SAM). SAM contains several spatial and mathematical models that have been designed and implemented for detecting landslides and flooding areas. Users can make an a...

This paper explores the developments which have precipitated the use and integration of Geographical Information Systems (GIS) within the South African Police Services (SAPS). The paper provides a historical overview of GIS within South Africa, supplemented with the legislative origins of the integration of GIS within policing in the country. Various geo-analytic operations that GIS technology ...

The earliest use of geographical information systems (GIS) in medicine possibly goes back to 1854, when John Snow mapped the outbreak of cholera in London and successfully traced the source of the disease. Years have now passed and the term ‘Geographic Information Systems’ was added to the controlled vocabulary thesaurus of US National Library of Medicine – MeSH (Medical Subject Headings) – in ...

The present study aims to design, develop, operate and evaluate a social media GIS (Geographical Information Systems) specially tailored to mash-up the information that local residents and governments provide to support information utilization from normal times to disaster outbreak times in order to promote disaster reduction. The conclusions of the present study are summarized in the following...

The paper introduces an overview on the researches we are currently carrying out on the integration of semantic aspects in Geographical Information Systems. Through an overview on the activities in the context of a project concerning the study of Bronze Age settlements in northern Italy, the paper shows how issues concerning semantics and GIS are currently faced to define an innovative and inte...
