ISO Platforms and Instruments

How ISO Does It

Most environmental datasets include observations that are made using instruments and, sometimes, platforms with multiple instruments. The characteristics of those instruments are, therefore, essential elements of the documentation for those instruments. Tracking changes in the instruments or their settings through time is also critical. The MI_Platform and MI_Instrument objects included in ISO 19115-2 provide a framework for connecting those descriptions to datasets.
