ISO 19156:2011定义了观察的概念模式，以及进行观察时取样所涉及的特征。这些模型为在不同科学和技术团体内部和之间交流描述观测行为及其结果的信息提供了模型。观察通常涉及对感兴趣的最终特征进行采样。ISO 19156:2011定义了一组常见的采样特征类型，主要按拓扑维度分类，以及用于异地观测的样本。模式包括采样特征（子采样、衍生样本）之间的关系。ISO 19156:2011只关注外部可见的接口，除了满足实际情况下的接口规范所需的内容外，对底层实现没有任何限制。

ISO 19156:2011 defines a conceptual schema for observations, and for features involved in sampling when making observations. These provide models for the exchange of information describing observation acts and their results, both within and between different scientific and technical communities.Observations commonly involve sampling of an ultimate feature-of-interest. ISO 19156:2011 defines a common set of sampling feature types classified primarily by topological dimension, as well as samples for ex-situ observations. The schema includes relationships between sampling features (sub-sampling, derived samples).ISO 19156:2011 concerns only externally visible interfaces and places no restriction on the underlying implementations other than what is needed to satisfy the interface specifications in the actual situation.
