Was ist INSPIRE ?

INfrastructure for SPatial InfoRmation in the European

CommunityDirective:

Obligation for the Memberstates to implement into national law and to provide the data according to the implementation rules

• Implemention rules needed to manage a harmonised IT-Infrastructure to provide Geo Data

• 34 Themes

• Partioned into Annex I to III
