- An indication of who the originating authority for obstacle data is. The data originator is considered to be the entity which performs measurements and represents it in the form of set of obstacles. Typically, this metadata should be collected for each obstacle represented.
The originator identifier is usually maintained by the entity storing obstacle data within the State but is not provided to the next intended user in the obstacle data set.
Description of obstacle DATA ORIGINATION as potential functions/responsibility in national TOD policy (source EUROCONTROL TOD Manual)
The organisation responsible for or owning objects in accordance with the national obstacle permission process and organisation responsible for the survey of obstacles and provision of quality-assured data
- The data origination entity in the data process is considered to be the organisation responsible for the obstacle in the national obstacle permission process. Different organisations may be responsible for obstacle data, for example:
- Area 1: obstacle owner;
- Area 2: aerodrome operator, obstacle owner, ANSP;
- Area 3, 4: aerodrome operator.
- The actual origination of the obstacle is done by surveying the obstacles and providing quality-assured data to the responsible organisation.
Data originator and obstacle owner are not necessarily the same entity e.g. data originator could be an entity providing an obstacle survey, but not being an obstacle owner. In any case, this information is useful for States in their obstacle management process and the data catalogue is a description of the data that can be collected by an AIS and not included the data products.
