    42、anguageO in feature-detection applications the initial observation may be made on a scene, but the entity to be detected, which is the ultimate feature-of-interest, occupies some location within it. The distinction between the proximate and ultimate feature-of-interest is a key consideration in thes

    43、e cases.Other locations appear in various scenarios. Sub-sampling at locations within the feature-of-interest may occur. The procedure may involve a sensor located remotely from the ultimate feature-of-interest (e.g. remote sensing; or where specimens are removed from their sampling location and obs

    44、ervations made ex-situ). Furthermore, the location of the feature-of-interest may be time-dependent.The model is generic. The geospatial location of the feature-of-interest may be of little or no interest for some observations (e.g. live specimens, observations made on non-located things like chemic

    45、al species).For these reasons, a generic Observation class does not have an inherent location property. Relevant location information should be provided by the feature-of-interest, or by the observation procedure, according to the specific scenario.NOTE In contrast to spatial properties, some tempor

    46、al properties are associated directly with an observation (7.2.2.2; 7.2.2.3). This is a consequence of the fact that an observation is a kind of event so its temporal characteristics are fundamental, rather than incidental.ISO 19156:2011(E) ISO 2011 All rights reserved 7BS EN ISO 19156:20137.1.5 Res

    47、ult typesObservation results may have many datatypes, including primitive types like category or measure, but also more complex types such as time, location and geometry. Complex results are obtained when the observed property requires multiple components for its encoding. Furthermore, if the proper

    48、ty varies on the feature-of-interest, then the result is a coverage, whose domain extent is the extent of the feature. In a physical realization, the result will typically be sampled discretely on the domain, and may be represented as a discrete coverage.The result type may be used as a basis for de

    49、fining specialized observation types.7.1.6 MeasurementsIn conventional measurement theory (e.g.15101119) the term “measurement” is used. However, a distinction between measurement and category-observation has been adopted in more recent work21221so the term “observation” is used here for the general concept. “Measurement” may be reserved for cases where the result is a numerical quantity.7.2 Observation schema7.2.1 PackagingThe observation schema is organized in one package containing eleven le
