Autor przedstawił koncepcję budowy geoserwisu udostępniającego zgromadzone w zasobie geodezyjnym i kartograficznym dane topograficzne VMap L2 w tzw. strukturze użytkowej oraz dane tematyczne SOZO i HYDRO, a także dane wysokościowe DTED2.

The author presented a concept of geoinformation service, which distributes reference (VMap L2) and thematic data (SOZO, HYDRO and DTED2), stored in the state resources of geodetic and cartographic data.

One of the tasks performed within the framework of the Project no 6 T 12 2005C/06552 is to develop a prototype information system which will make reference and thematic data accessible. The objective of this work was to promote valuable topographic and thematic data, which are stored in the State Geodetic and Cartographic Resource (PZGiK), as well as to promote the idea of utilisation of so-called free software, which allows inexpensive and effective publication of geographical data in Internet. The authors attempted to develop a regional portal with the use of free software and OGC standards. GeoServer ver. 1.5.4 software was used as a map server for geoinformation services. Tile Cache ver. 1.9 software was also used; it ensures efficient access to data. Map displays on the browser's side are maintained by OpenLayers ver. 2.5 software. Spatial data are stored in the Oracle Express 10g database. The geoinformation services, using Google technology, ensures the access to reference and thematic data, which are cartographically edited. The VMap L2 database, which is accessible in the PZGiK, has been used as the source reference spatial database; it is the only database which has been developed for the entire country. In order to rationally utilise VMap L2 data of the first edition, the idea to convert this database into so-called useful structure has been proposed; the useful structure is characterised by a highly simplified conceptual model and modified topology. The second component of services are thematic SOZO and HYDRO data, stored in the PZGiK, developed for more than 55% of Poland. Due to the fact that sozological and hydrograhical databases have been developed on the background of the VMap L2, complete harmonisation of those products, as well as their common Internet publication in geoinformation services is possible. Considering the level of details corresponding to analogue maps at the scale of 1:50 000, it is reasonable to amend visualisation of selected reference and thematic data with satellite images, distributed by Google Maps services. This solution, known from mixed (mashup) services, allows attractive and functional presentation of selected areas.
