The development of fuzzy sets in geographic information systems (GIS) arose out of the need to handle uncertainty and the ability of soft computing technology to support fuzzy information processing. An overview of the fundamentals of fuzzy sets is used to illustrate its use in GIS. The use of some terms within both the GIS and fuzzy information processing community is clarified. Since one of t...

Despite the progress in critical geographic information systems (GIS) research in recent years [1], geographical discourse is still dominated by dualist thinking that understands GIS largely as a tool for quantitative or empiricist spatial analysis. This dualist understanding of geographical methods—which was partly fuelled by the erce polemics between critical geographers and GIS users/researc...

All kind of data is the important component of a GIS studies. The data which will be used for GIS works is mostly provided from an digitized maps, existing paper maps, areal photos or satellites images. Nowadays the data from GPS can be used to make plans and maps of the studied area and the GPS data can be converted into the GIS environment more easily. GIS and GPS integration systems have som...

he expanding presence of geographic information system (GIS) offices within organizations has helped to enhance the availability of GIS data and expertise, but not always to the benefit of the entire organization within which it is working. The separation— and frequently, isolation—of GIS specialists within agencies, institutions, and organizations often limits the potential usefulness of GIS t...

With the fast development of cities in China, more and more geographic information systems (GIS) that have been combined with remote sensing information are applied to help decision-maker or company to manage and make macroscopic decisions. But the accuracy of integrated GIS was ignored by both user and producer. It followed that the uncertainty of GIS may result in wrong decision. For these re...

Like in most other countries, influenza surveillance in The Netherlands is based upon influenza-like illness (ILI) consultations reported by sentinel general practitioners (GP). In addition, an internet-based monitoring of ILI in the general population started in 2003/2004 (Great Influenza Survey (GIS)). We compared GIS results over 5 influenza seasons with results from the GP system. Weekly IL...
