Definitions

  • Airports > With paved runways > 1,524 to 2,437 m: This entry is derived from Transport > Airports > With paved runways, which gives the total number of airports with paved runways (concrete or asphalt surfaces) by length. For airports with more than one runway, only the longest runway is included according to the following five groups - (1) over 3,047 m (over 10,000 ft), (2) 2,438 to 3,047 m (8,000 to 10,000 ft), (3) 1,524 to 2,437 m (5,000 to 8,000 ft), (4) 914 to 1,523 m (3,000 to 5,000 ft), and (5) under 914 m (under 3,000 ft). Only airports with usable runways are included in this listing. Not all airports have facilities for refueling, maintenance, or air traffic control. The type aircraft capable of operating from a runway of a given length is dependent upon a number of factors including elevation of the runway, runway gradient, average maximum daily temperature at the airport, engine types, flap settings, and take-off weight of the aircraft.
  • Airports > With unpaved runways > 1,524 to 2,437 m: This entry is derived from Transport > Airports > With unpaved runways, which gives the total number of airports with unpaved runways (grass, dirt, sand, or gravel surfaces) by length. For airports with more than one runway, only the longest runway is included according to the following five groups - (1) over 3,047 m (over 10,000 ft), (2) 2,438 to 3,047 m (8,000 to 10,000 ft), (3) 1,524 to 2,437 m (5,000 to 8,000 ft), (4) 914 to 1,523 m (3,000 to 5,000 ft), and (5) under 914 m (under 3,000 ft).

  • Airports > With unpaved runways > Under 914 m: Total number of airports with useable unpaved runways (grass, dirt, sand, or gravel surfaces), categorised according to the length of the longest runway
  • Heliports: Total number of established helicopter take-off and landing sites (which may or may not have fuel or other services).
  • Merchant marine > Foreign-owned: Merchant marine may be defined as all ships engaged in the carriage of goods; or all commercial vessels (as opposed to all nonmilitary ships), which excludes tugs, fishing vessels, offshore oil rigs, etc. This entry contains information in four fields - total, ships by type, foreign-owned, and registered in other countries.
    Total includes the number of ships (1,000 GRT or over), total DWT for those ships, and total GRT for those ships. DWT or dead weight tonnage is the total weight of cargo, plus bunkers, stores, etc., that a ship can carry when immersed to the appropriate load line. GRT or gross register tonnage is a figure obtained by measuring the entire sheltered volume of a ship available for cargo and passengers and converting it to tons on the basis of 100 cubic feet per ton; there is no stable relationship between GRT and DWT.
    Ships by type includes a listing of barge carriers, bulk cargo ships, cargo ships, chemical tankers, combination bulk carriers, combination ore/oil carriers, container ships, liquefied gas tankers, livestock carriers, multifunctional large-load carriers, petroleum tankers, passenger ships, passenger/cargo ships, railcar carriers, refrigerated cargo ships, roll-on/roll-off cargo ships, short-sea passenger ships, specialized tankers, and vehicle carriers.
    Foreign-owned are ships that fly the flag of one country but belong to owners in another.
    Registered in other countries are ships that belong to owners in one country but fly the flag of another.
  • Merchant marine > Total: 1000 GRT or over
  • Pipelines > Gas: Total length of gas pipelines
  • Ports and terminals: This entry lists major ports and terminals primarily on the basis of the amount of cargo tonnage shipped through the facilities on an annual basis. In some instances, the number of containers handled or ship visits were also considered.
  • Railways > Standard gauge: This entry states the total route length of the railway network and of its component parts by gauge: broad, dual, narrow, standard, and other.
    Standard gauge=1.435-m gauge
  • Railways > Total: This entry states the total route length of the railway network and of its component parts by gauge: broad, dual, narrow, standard, and other.
  • Roadways > Paved: This entry is derived from Transport > Roadways, which gives the total length of the road network and includes the length of the paved and unpaved portions.
  • Roadways > Total: This entry gives the total length of the road network and includes the length of the paved and unpaved portions.
  • Roadways > Unpaved: This entry gives the total length of the road network and includes the length of the paved and unpaved portions.
