Inland Waterway Network - ArcInfo Coverage
The attribute information of the ArcInfo inland waterway coverage is contained in the
Arc Attribute Table (AAT) and the Node Attribute Table (NAT). The following
table shows the contents of the Arc Attribute Table:
Notes: LINKTYPE and NAME give general information on links. Port links are links representing docks/facilities of a port. FLINKCAT indicates the future link category, i.e. if the waterway is under construction or improvement, while PLINKCAT indicates the current link category. If a waterway will not change its waterway class, PLINKCAT and FLINKCAT have the same value. However, information on improvements/construction are not available for all TEN links. In these cases FLINKCAT has value of zero. TENCAT and TENALIGN give information on those links which are included in the "Trans European Transport Network Outline Plan, Section Inland Waterways" and are taken from the "Joint Decision of the European Parliament and of the Council" published in the Official Journal of the European Communities (L228, 9 September 1996). A planned TEN link in association with unknown alignment (TENCAT = 2 and TENALIGN = 2) represents a planned inland waterway link to be constructed, whereas a planned TEN link with known alignment (TENCAT = 2 and TENALIGN = 1) represents improvements of existing waterways (e.g. extension, widening). STRATEGIC indicates whether a link is part of the strategic inland waterway network. The strategic inland waterway network is a subset of the total network used in the DGVII project STREAMS and STEMM. The strategic inland waterway network contains the trans-European Inland Waterway links specified in Decision 1692/96/EC of the European Parliament and of the Council and the east European corridors identified by the Second Pan-European Transport Conference in Crete in 1994 as well as selected additional links in eastern Europe and further links to guarantee connectivity of regions and centroids. The following table shows the contents of the Node Attribute Table:
Notes: NODEID1 is a unique identifier for each node in the network. The first three digits indicate the number of the region in which the node is located. COUNTRY1 is the ISO code of the country in which the node is located. REGION1 is a four-character acronym of the name of the region. The regions are regions of the system of regions defined for the STREAMS and SASI projects. They correspond largely to NUTS-2 regions defined by Eurostat plus equivalent extensions outside the European Union. A more detailed description of the system of regions is available. Normally only one node number, country code and region code are associated with a node. However in the case of border nodes (NODETYPE = 1) or if a node is located along a border river (NODETYPE = 15), NODEID2, COUNTRY2 and REGION2 are used to indicate that the node is also part of the waterway network of the neighbouring country. Border nodes are nodes where rivers cross a border, whereas border river nodes are nodes along a border river. With the exception of river mouths, seaports, port nodes and end nodes all other nodes may have also entries in NODEID2, COUNTRY 2 and REGION2 if they are located along a border river. Lock nodes represent locks with one chamber, double locks represent locks with two parallel chambers, and lock system nodes represent several locks in line with unknown location and unknown number of chambers per lock. LOCKS indicates the number of locks in line, CHAMBERS the number of parallel chambers per lock. PORTNUMBER represents a unique number for each port of international importance included in the waterway network. PORTNAME indicates the name of the port. © 2002 IRPUD Home | Data Formats | Contact | IRPUD |
