How data and services are being used  On-line services (WMS, WFS)  Working with up-to-date data (2 hours old)  Easy use  Limited range of data  Pre-defined data sets  Possibility of analysing large amount of data  Necessity to maintain own database  Not working on up-to-date data (essential dynamics of change)  Most of our customers is using both concepts Otevřená data: chytřejší stát a lepší službyStránka 11

Conclusions RÚIAN as a part of the Czech e-government has introduced the Open Data concept for some important spatial data sets linked with the Czech Cadastre of Real Estates, these data is wildly used. Open spatial data services harmonized acording to the INSPIRE directive became an attractive alternative for some sorts of users as it is much easier to implement it Otevřená data: chytřejší stát a lepší službyStránka 12
