GIS research has a continuing threaddevoted to classifying the operations performed by analytical software. Prior e€ orts to classify GIS operations have limitations and inconsistencies, often arising from an attempt to establish overly direct links between geographic procedures and arithmetical operations. The transformational view of cartography provides a more solid basis for classifying GIS...

We present an architecture of collaborating software agents which is supposed to tackle the problem of information integration in a flexible and generic way. An intended system is supposed to offer a transparent view onto information resources (data sources and software tools) for genomic research and to be able to adopt to the constantly evolving environment. This framework architecture is cur...

As the geographic information system (GIS) community grows, more and more people needs to share geographic information. As modern GIS data is stored in geographic databases their conceptual schemas have to be, at least, interoperable. Due to the fact that the databases are designed by many different people from different countries, using different languages and maybe with different definitions ...

Emergency management/Emergency service is a compelling domain for applying GIS Web Service. GIS Web Service expands the further development of GIS. A Web service is described using XML-standards like the WSDL (Web Service Description Language). Web Services, are different from Web applications, don’t require people to use; but software applications to call. Thus, the Web service does not have a...

Current advances in wireless technology supported by the development of customized GIS applications, can significantly enhance field data collection, processing and visualization in environmental research. A distributed wireless sensor network was designed to collect and remotely transmit data in real-time to an in-house geodatabase, to monitor the long-term natural attenuation of groundwater c...

GIS and Modeling Overview MICHAEL F. GOODCHILD NATIONAL CENTER FOR GEOGRAPHIC INFORMATION AND ANALYSIS UNIVERSITY OF CALIFORNIA SANTA BARBARA, CALIFORNIA Modeling can be defined in the context of geographic information systems (GIS) as occurring whenever operations of the GIS attempt to emulate processes in the real world, at one point in time or over an extended period. Models are useful and u...
