3 Non-geometry standards
How is a profile defined?
• A profile is a subset of the base standards of the ISO 19100 family of standards or
other Information Technology standards.
• A profile determines how they are used together.
• A profile explains the usage details as far as required.
ISO 19106 distinguishes between two types of profiles.
• The conformance level 1 designates a profile that is purely derived from elements
of the ISO 19100 family of standards and possibly other ISO standards.
• The conformance level 2 specifies profiles that integrate elements of non-ISO
standards with elements from the ISO standards.
The development of profiles has been opened according to conformance level 2
because the existing suite of standards cannot yet claim to meet all requirements.
This is despite the great effort that has been put into a generalized and comprehensive approach towards geographie information. A profile of conformance level 2
cannot become an ISO standard ofthe type International Standardised Profile.
