The fairway characteristics are part of the EuRIS reference data. The data set contains the IDs, names and other parameters of the fairway sections relevant for navigation. The data sets on the EuRIS API also contain international data sets of partner states that implement selected types of services according to Directive 2005/44/EC of the European Parliament and of the Council on harmonised river information services (RIS) on inland waterways in the Community.

Hydrometeorological information includes previous, current and predicted water levels and discharges data at control waterway gauges. The datasets on the EuRIS API also include international datasets from partner countries that implement selected types of services according to Directive 2005/44/EC of the European Parliament and of the Council on harmonised river information services (RIS) on inland waterways in the Community. This dataset includes data from the dataset "Current and future water levels at water meters" according to Annex 6 to Commission Implementing Regulation (EU) 2023/138, which establishes a list of specific high-value datasets and measures for their publication and reuse.

Inland Electronic Navigational Charts (IENC) are specialized digital charts designed for information systems for displaying inland electronic navigational charts (IECDIS). These systems are intended primarily for on-board navigation equipment. IENC maps represent RIS information items according to Section 4 of Decree No. 356/2009 Coll. on information recorded in River Information Services. The map standard is defined according to the current version of the Encoding Guide for Inland Electronic Navigational Charts (Encoding Guide for Inland ENCs). Data sets on the EuRIS API in the form of digital charts also contain international IENCs of partner states that apply selected types of services according to Directive 2005/44/EC of the European Parliament and of the Council on harmonised river information services (RIS) on inland waterways in the Community. Each map sheet on the EuRIS API has its own identifier (mapID) and a name according to the waterway section (name). The link to a clear list of all map sheets on the EuRIS portal is: https://www.eurisportal.eu/enc

Location and characteristics of berths are part of the EuRIS reference data dataset. The dataset contains IDs, names and other parameters of vessel locations. The datasets on the EuRIS API also contain international datasets of partner countries that implement selected types of services according to Directive 2005/44/EC of the European Parliament and of the Council on harmonised river information services (RIS) on inland waterways in the Community. This dataset includes data from the dataset "Location and characteristics of ports and transhipment sites" according to Annex 6 of the Commission Implementing Regulation (EU) 2023/138, laying down a list of specific high-value datasets and the arrangements for their publication and re-use.

This distribution of the dataset contains personal data in the meaning of Act No. 101/2000 Sb., on personal data protection and Regulation (EU) 2016/679 on the protection of natural persons with regard to the processing of personal data and on the free movement of such data, and repealing Directive 95/46/EC (General Data Protection Regulation). With download of this distribution you are becoming personal data controller. Thus, you must comply with all the rules and duties which arise from the applicable legal regulation. Especially, you must comply with the duty to process personal data only for legal and legitimate purpose, in a way that is adequate for such purpose and for the time that is necessary for such purpose. You also have to have a lawful legal ground for the processing.

Notices to Skippers contain dynamic information on current and future changes in the traffic status on inland waterways. The messages are divided into four categories: fairway and traffic related messages (FTM), water level related messages (WRM), weather related messages (WERM) and ice messages (ICEM). The datasets on the EuRIS API also contain international datasets from partner countries that implement selected types of services according to Directive 2005/44/EC of the European Parliament and of the Council on harmonised river information services (RIS) on inland waterways in the Community. This dataset includes data from the dataset "Other physical limitations on waterways, Temporary obstructions in the fairway, Restrictions caused by floods and ice" and "Short term changes of lock and bridge operating times" according to Annex No. 6 of Commission Implementing Regulation (EU) 2023/138 establishing a list of specific high-value datasets and measures for their publication and re-use.

Operational information means basic information about navigational objects, their operating times and contacts. Operational information represents RIS information items according to Section 4 of Decree No. 356/2009 Coll. on information recorded in River Information Services. The input format is governed by the XML standard for facility files and is defined according to the current version of the Encoding Guide for Inland ENCs. Data sets on the EuRIS API also contain international data from partner states that apply selected types of services according to Directive 2005/44/EC of the European Parliament and of the Council on harmonised river information services (RIS) on inland waterways in the Community. To filter the data of a specific object, it is necessary to enter its so-called ISRS code in the EuRIS API. The current list of ISRS codes for the Czech Republic is given in the so-called RIS Index on the EuRIS portal page after checking the filters "Country: Czech Republic" and "Function: Lock, Lift Bridge". The link to the RIS Index list is: https://www.eurisportal.eu/waterway/risindex
