    <subfield code="a">&lt;p&gt;This paper discusses the ontological status of remote sensing images, from a GIScience perspective. We argue that images have a dual nature&amp;mdash;they are fields at the measurement level and fiat objects at the classification level&amp;mdash;and that images have an ontological description of their own, distinct and independent from the domain ontology a domain scientist uses. This paper proposes a multi-level ontology for images, combining both&amp;nbsp;&lt;em&gt;field&lt;/em&gt;&amp;nbsp;and&amp;nbsp;&lt;em&gt;object&lt;/em&gt;approaches and distinguishing between image and user ontologies. The framework developed contributes to the design of a new generation of integrated GISs, since two key benefits are achieved: (1) the support for&amp;nbsp;&lt;em&gt;multiple&lt;/em&gt;&amp;nbsp;&lt;em&gt;perspectives for the same image&lt;/em&gt;&amp;nbsp;and (2) an emphasis on using images for the detection of&amp;nbsp;&lt;em&gt;spatial-temporal configurations of geographic&lt;/em&gt;&lt;em&gt;phenomena&lt;/em&gt;.&lt;/p&gt;</subfield>
