b) support the following air navigation applications: 1) instrument procedure design (including circling procedure); 2) aerodrome obstacle restriction and removal; and 3) provision of source data for the production of other aeronautical charts. 5.2 Availability 5.2.1 From 18 November 2010, Aerodrome Terrain and Obstacle Charts — ICAO (Electronic) shall be made available in the manner prescribed in 1.3.2 for all aerodromes regularly used by international civil aviation. Note 1.— Where the Aerodrome Terrain and Obstacle Chart — ICAO (Electronic) is made available, the Aerodrome Obstacle Chart — ICAO Type A (Operating Limitations) and the Aerodrome Obstacle Chart — ICAO Type B are not required (see 3.2.1 and 4.2.1). Note 2.— The information required by the Precision Approach Terrain Chart — ICAO may be provided in the Aerodrome Terrain and Obstacle Chart — ICAO (Electronic). Where this occurs the Precision Approach Terrain Chart — ICAO is not required (see 6.2.1). 5.2.2 Recommendation.— Aerodrome Terrain and Obstacle Charts — ICAO (Electronic) should be made available in the manner prescribed in 1.3.2 for all aerodromes regularly used by international civil aviation. 5.2.3 The Aerodrome Terrain and Obstacle Chart — ICAO (Electronic) shall also be made available in hard copy format upon request. Note.— For specifications regarding hard copy printed output see 5.7.7. 5.2.4 The ISO 19100 series of standards for geographic information shall be used as a general data modelling framework. Note.— The use of the ISO 19100 series of standards for geographic information supports the interchange and use of the Aerodrome Terrain and Obstacle Chart — ICAO (Electronic) among different users. 5.3 Identification Electronic charts shall be identified by the name of the country in which the aerodrome is located, the name of the city or town which the aerodrome serves, and the name of the aerodrome. 5.4 Chart coverage The extent of each chart shall be sufficient to cover Area 2 as specified in Annex 15, 10.2. 5.5 Chart content 5.5.1 General 5.5.1.1 When developing computer graphic applications that are used to portray features on the chart, the relationships between features, feature attributes, and the underlying spatial geometry and associated topological relationships shall be specified by an application schema. Portrayed information shall be provided on the basis of portrayal specifications applied according to defined portrayal rules. Portrayal specifications and portrayal rules shall not be part of the data set. Portrayal rules shall be stored in a portrayal catalogue which shall make reference to separately-stored portrayal specifications. Note.— ISO Standard 19117 contains a definition of the schema describing the portrayal mechanism of feature-based geographic information, while ISO Standard 19109 contains rules for application schema. Spatial geometry and associated topological relationships are defined in ISO Standard 19107. Annex 4 — Aeronautical Charts Chapter 5 1/11/01 5-2 22/11/07 No. 54 5.5.1.2 Symbols used to portray features shall be in accordance with 2.4 and Appendix 2 — ICAO Chart Symbols. 5.5.2 Terrain feature 5.5.2.1 The terrain feature, and associated attributes, to be portrayed and database linked to the chart shall be based on the electronic terrain data sets which satisfy the requirements of Annex 15, Chapter 10 and Appendix 8. 5.5.2.2 The terrain feature shall be portrayed in a manner that provides an effective general impression of a terrain. This shall be a representation of terrain surface by continuous elevation values at all intersections of the defined grid, also known as the Digital Elevation Model (DEM). Note.— In accordance with Annex 15, Chapter 10 and Appendix 8, the DEM for Area 2 post spacing (grid) is specified at 1 arc second (approximately 30 m). 5.5.2.3 Recommendation.— Representation of terrain surface should be provided as a selectable layer of contour lines in addition to the DEM. 5.5.2.4 Recommendation.— An ortho-rectified image which matches the features on the DEM with features on the overlying image should be used to enhance the DEM. The image should be provided as a separate selectable layer. 5.5.2.5 The portrayed terrain feature shall be linked to the following associated attributes in the database(s):
