The INSPIRE Hydrography data are harmonised according to INSPIRE implementing rules and conform to the INSPIRE XML schema version 4.0. The dataset is processed according to the Hydro-Network application schema. This hydrography dataset for the Czech Republic therefore has a unified structure consistent with other data produced for this INSPIRE theme across Europe. Objects are represented by a vector component with attributes containing additional information about the objects. The source dataset is the Fundamental Base of Geographic Data of the Czech Republic (ZABAGED®).
