  1. Cartography at the International Civil Aviation Organization

  2. The International Civil Aviation Organization • specialized agency of the United Nations • sets international standards for the safety, security, efficiency and regularity of air transport • improving safety is ICAOs main activity • serves as a medium for co-operation among its 185 member States

  3. Background information about ICAO • headquarters in Montreal • seven regional offices • Bangkok, Cairo, Dakar, Lima, Mexico, Nairobi and Paris • technical standards for most aspects of international civil aviation are contained in the 18 ICAO Annexes to the Convention on International Civil Aviation

  4. Annex 4 - Aeronautical Charts • contains Standards and recommended practices for 17 types of aeronautical charts • ICAO does not produce these operational charts - they are published and distributed by the civil aviation authorities of ICAO member States • Planning and visual navigation charts • Aeronautical Chart - ICAO Small scale • World Aeronautical Chart - ICAO 1:1 000 000 • Aeronautical Chart - ICAO 1:500 000

  5. Annex 4 - Aeronautical Charts • Instrument flight rules (IFR) charts • Enroute Chart - ICAO • Plotting Chart - ICAO • Area Chart - ICAO • Standard Arrival Chart - Instrument (STAR) - ICAO • Standard Departure Chart - Instrument (SID) - ICAO • Instrument Approach Chart - ICAO

  6. Annex 4 - Aeronautical Charts • Charts of the aerodrome and vicinity • Visual Approach Chart - ICAO • Aerodrome /Heliport Chart - ICAO • Aerodrome Ground Movement Chart - ICAO • Aircraft Parking/Docking Chart - ICAO • Aerodrome Obstacle Charts • Aerodrome Obstacle Chart - ICAO • Types A, B and C • used for calculating aircraft performance limitations

  7. Annex 4 - Aeronautical Charts • includes specifications for colour and symbology • requirement for all geographical coordinates to be stated in terms of the WGS-84 geodetic reference datum • Includes aeronautical data quality requirements • supported by the ICAO Aeronautical Chart Manual and WGS-84 Manual

  8. Regional Planning • requirement for civil aviation authorities to plan and implement air navigation facilities in cooperation with each other • world is divided into seven ICAO regions • each has its own Air Navigation Plan Publication (ANP) which is frequently amended

  9. Regional Planning • Air Navigation Plans contain detailed tabulations of planned air navigation facilities with associated charts • include charts of flight information regions, air routes, aids to navigation, aerodrome usage, search and rescue, MET, COM and AIS facililties • not for operational use

  10. Airport characteristics databank • provides information on over 1000 of the worlds main airports • runway lengths, slopes, bearing strengths, lighting, obstacles, etc. • data from State AIPs and ICAO missions • intended for planning purposes not operational use

  11. ICAO cartographic unit • Air Navigation Bureau, AIS/MAP Section • MapGrafix, ArcView, Adobe Illustrator • basic back ground political map is from digital chart of the world • aeronautical data is from ICAO regional meetings, regional planning groups and approved ANP amendment proposals • Microsoft Excell and Filemaker Pro • Adobe Acrobat pdf

  12. Problems • our ANP amendment process is not as efficient as it could be • goal to give ICAO regional offices charting and GIS functionality through the WEB • two way link between the data base and chart required with an amendment history • difficult to ascertain and plot appropriate political boundary representations • world elevation data would be useful

  13. Formats • shape files- shp,shx,dbf • ANP chart scale - typically 1: 5 000 000 • for special projects 1: 500 000 and larger • multiscale data base would be useful • accuracy (usually to one second), elevations/heights to 3m or 1m • geodetic datum - WGS-84

  14. Other ICAO AIS/MAP documents • Aeronautical Chart Catalogue (Doc 7101) • Aeronautical Information Services Provided by States (Doc 7383) • Location Indicators (Doc 7910), • Designators for Aircraft Operating Agencies, Aeronautical Authorities and Services (Doc 8585) • Aircraft Type Designators(Doc 8643)
