042     * Observations may be associated with a geospatial location. The primary location of
043     * interest is usually associated with the ultimate feature-of-interest, so this is a principle
044     * classifier of an observation and its result, used in indexing and discovery.
045     *
046     * However, the location may not be trivially available. For example: in remote sensing
047     * applications, a complex processing chain is required to geolocate the scene or swath; in
048     * feature-detection applications the initial observation may be made on a scene, but the
049     * detected entity, which is the ultimate feature of interest, occupies some location within it.
050     * The distinction between the proximate and ultimate feature of interest is a key
051     * consideration in these cases (see sub-clauses 6.3.1 and O&M-Part 2).
