Using Web Services to enhance Geographic Information Systems

Ladner R., Petry F., Warner E., Gupta K.

Vol. 35, no 1

29-46

In this paper we describe an approach to the extension of geographic information systems to take advantage of the continuing development of capabilities of the Semantic Web. This is presented in the context of a portal based Geospatial Information Database (GIDB™), an object-oriented spatial database capable of storing multiple data types from multiple sources. We have developed our approach for a specific domain, spatially oriented, meteorological and oceanographic, but this can clearly be applied to other Spatial data domains. Finally we illustrate the use of the ontology development system based on Generative Sublanguage Ontologies (GSO), a type of linguistic ontology inspired by the Generative Lexicon Theory, to develop effective domain ontologies.

The main goal of the TRANSCAT project is to create an operational and integrated comprehensive Decision Support System (DSS) for optimal water management of catchments in borderland regions. The analysis of system requirements was followed by the analysis of possible architecture of the complex system and its appropriate design. The core of the proposed system (ETRA GIS) contains gis-Toolkit, web server, DBS, database interface, web services application interface and remote components. The system utilises selected software tools of hvdrological and hvdrogeological modelling (HEC-HMS, ModFlow, GRASS GIS modules). The special wrappers for each of the model were developed, enabling communication among models. Decision-making is supported by integrated decision applications (mDSS, Mediator, ProDec, BarTend, ArgWar) facilitating mainly the process of evaluation of a wide spectrum of indicators and the process of decision-making. The core of the system utilises a database with special design. The object part of the database represents a data warehouse with multidimensional structure. Implementation of TDSS was undertaken in Bela/Biala Glucholaska (CZ/PL), Pasvik (NO/RUS), Sumava (CZ/D), Mesta/Nestos (BG/GR) and Guadiana (P/ESP) pilot areas, where also respective models were calibrated.
