ISO 6709 - Representation at The Human Interface (Annex D)

Representation At The Human Interface (Annex D)

When there is no guideline given from the user community, the following styles are suggested:

1. Coordinate values (latitude, longitude, and altitude) should be delimited by spaces.
2. The decimal point is a part of the value, thus must usually be configured by the operating system.
3. Multiple points should be represented by multiple lines.
4. Latitude and longitude should be displayed by sexagesimal fractions (i.e. minutes and seconds).
5. When minutes and seconds are less than ten, leading zeroes should be shown.
6. Degree, minutes and seconds should be followed by the symbols ° (U+00B0), ' (U+0027), and " (U+0022), without spaces between the number and symbol.
7. North and south latitudes should be indicated by N and S following immediately after the digits.
8. East and west longitudes should be indicated by E and W following immediately after the digits.
9. Units of elevation or depth should be given by symbols, immediately after the digits.
10. Elevation below reference level or depth above reference level should be indicated by a minus sign (-).

Examples:

• 50°40'46,461"N 95°48'26,533"W 123,45m
• 50°03'46.461"S 125°48'26.533"E 978.90m
