Abstract

The contribution describes general principles of the web services and XML applications. Importance and advantages of their utilization are explained. A detailed orientation is then aimed at the Web Map Services (WMS) being developed on the basis of the Open GIS Consortium (OGC). These services enable e.g. on-line composition of thematic maps defined by the user in an Internet browser window, from data being provided by servers with WMS. Thus the user does not need to own any data, although he can compose a topical thematic map representing a chosen territory, and the map contents he specifies himself.

In the contribution a particular example of a web XML application for on-line calculations is given, with a utilization of WMS for presentation of their results as well. Necessary principles, advantages and the importance of XML format are very briefly explained, so that any reader can fully understand the mentioned principles of services founded on this format.

About the author

Milan Talich graduated from the Czech Technical University in Prague, Faculty of Civil Engineering, Department of Geodesy and Cartography. Then he was engaged in the Research Office of Geodesy, Topography and Cartography, working since 1987 in the International Centre of Earth´s Recent Crustal Movement (ICRCM) at geodetic networks processing and geodynamic problems. In 1992 - 1993 he was at one-year stage in the Institute of Applied Geodesy in Frankfurt/Main (IfAG), where he compiled the Czech, Slovak and Hungarian parts of the European Reference System (EUREF) GPS network. Then he was engaged in solutions of GPS processing oriented to geodynamic applications and to questions related to deformation analysis of those data. Since 1995 he solved some problems of informatics in the Branch Information Centre (ODIS) of the VÚGTK. He was author and leader of research group of the research task Automation of Library of ODIS. At present he works at information systems oriented to web information.

In 2002, Milan Talich presented his doctorial thesis "Information Systems to On-Line Providing of Geodetic Information and Their Creation". He became leader of ODIS on the base of a selection procedure at the beginning of 2003.
