This tutorial gives an introduction to the standard data-access protocols Web Coverage Service (WCS) 2.0 and its extension Web Coverage Processing Service (WCPS) 1.0. Both standards are defined by the Open Geospatial Consortium (OGC). The tutorial provides (i) a general introduction to web standards for geospatial data and (ii) practical hands-on exercises how to access, retrieve and process data served with a WCS server. After working through the tutorial, you should have a clearer idea of OGC standards for geospatial data in general, the purpose and importance of the WCS and WCPS standards, how data can be accessed, processed and retrieved with the help of a WC(P)S, and how WC(P)S requests can easily be integrated into processing routines or used to build custom web-applications.
