The international Summer School EnviSDI aims at establishing a European education network to improve the access to spatial environmental data for public sector bodies, private companies and citizens. The Summer School considers aspects of data organization, data harmonization as well as semantic and technical interoperability in order to produce seamless geospatial information across Europe and to improve the data access for a wide community of different user groups. Learning about methodologies and the application of structural specifications for the description and harmonization of spatial environmental data within Europe as well as the operation of a corresponding Spatial Data Infrastructure (SDI) are main objectives. Participants will establish and operate an education network (SDIe_NET) dealing with services for spatial datasets and metadata. The ultimate training objective of the Summer School is to jointly set up a (geo-) web service to discuss data schemes from different disciplines in order to understand the challenge of arriving at one denominator within a very heterogeneous field of researchers and applications. Participants have the opportunity to attend sessions at the GI Forum 2010 (>http://www.gi-forum.org/) and the AGIT Symposium (>http://www.agit.at).
