Scope

GB/T 41554-2022 is the English-translated version of 地理空间观测平台及传感器资源元数据.

GB/T 41554-2022 fixes the metadata that describe geospatial observation platforms and sensors so that those resources can be shared and applied.

For platforms, spaceborne, airborne, ground fixed and ground mobile, and for sensors, including optical, LiDAR and microwave ones, it specifies the general metadata information, the identification of the observation resource, the observation capability information, the observation result information, the constraint information, the contact information and the log information.

Two normative annexes give the marks and identifiers used in the UML structure diagrams and the data dictionary description. It defines observation platform, observation resource and sensor, and cites GB/T 19710-2005, GB/T 19710.2-2016, GB/T 22022-2008 and GB/T 35643-2017 among others. It was issued on 11 July 2022 and has applied since that day.
