Notes:

NODEID is a unique number for each airport in the database. The first three digits indicate the number of the region in which the airport is located. COUNTRY indicates the ISO code of the country in which the airport is located. REGION 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.

IATA and ICAO indicate the airport identifiers used in international air traffic. These codes are not given for all airports. Some smaller airports with only regional importance have no IATA or ICAO code.

TENCAT, TENAS, PRIORITY and CATEGORY give information on those airports which are included in the "Trans European Transport Network Outline Plan, Section Airports" 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) and those airports included in the TINA programme. Although the additional airports of the strategic network are not included in the TEN programme, they have been used for modelling accessibilities in a number of research projects. Information on those links which are included in the TINA networks are taken from "TINA Transport Infrastructure needs Assessment. Identification of the Network Components for a future trans-European Transport Network in Bulgaria, Cyprus, Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, Romania, Slovakia and Slovenia" (TINA Secretariat 1999) as agreed in the European Union and the candidate countries. The TEN priority project number represents the "specific" projects adopted in 1996 (so called "Essen list") and potential "specific" projects as defined by the European Parlament and the council in 2001.
