# # On-demand geospatial data access via standard webservices | Tutorial

#  

# This tutorial gives an introduction to the standard data-access protocols [Web Coverage Service](http://www.opengeospatial.org/standards/wcs) (WCS) 2.0 and its extension [Web Coverage Processing Service](http://www.opengeospatial.org/standards/wcps) (WCPS) 1.0.   Both standards are defined by the [Open Geospatial Consortium](http://www.opengeospatial.org) (OGC).  
# 
# In the framework of the H2020-funded [EarthServer-2](http://earthserver.eu) project, the European Centre of Medium-Range Weather Forecasts (ECMWF) is setting up a WCS server in order to study the feasibility and to demonstrate the potential of efficient web-based data access via WCS and WCPS interfaces. You can find more information about ECMWF's role within EarthServer [here](http://ecmwf.int/en/research/projects/earthserver-2).
# 
# This 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.  
# 
# 
# We are very interested in your feedback. Please let us know your experiences working with a WCS service and furthermore, your individual requirements of a web-service like this. We also appreciate any constructive feedback to this tutorial.
# 
# **Enjoy exploring WCS and WCPS!**
