V članku je podan pregled in možnosti uporabe
prostih spletnih servisov in standardnih vmesnikov
za prostorske podatke, ki jih je razvil in jih vzdržuje
konzorcij OGC (Open Geospatial Consortium).
Poleg kratkega pregleda različnih pristopov in izvedb
spletnih servisov so podrobneje predstavljeni najbolj
pomembni standardni spletni servisi OpenGIS.
Opisane so značilnosti, prednosti in slabosti teh
na XML temelječih pristopov za komunikacijo in
izmenjavo prostorskih podatkov ter težave, ki se
lahko pojavijo pri tovrstnih aplikacijah. Omenjena so
glavna področja uporabe prostih spletnih servisov za
prostorske podatke na splošno in posebej za geodetsko
stroko glede na dostop do porazdeljenih baz podatkov
in spletne kartografske predstavitve.

| Abstract: |
|---|
This paper presents an overview and possibilities for the usage of open web services and standardized interfaces for spatial data that are developed and maintained by the OGC (Open Geospatial Consortium). Besides the short overview of various approaches and implementation of web services, this paper focuses on the most frequently applied OpenGIS standard services that are based on the XML meta-language for the exchange of messages and spatial data transfer The concluding remarks outline the main existent and potential application domains of open web services in the field of surveying, with regard to the access to distributed databases and web cartographic presentations.
