| Type of standard | ISO International Standard Meta level |
| Application | This part of ISO 19125 describes the common architecture for simple feature geometry. |
| Conformance classes | Geometry model Correspondence – Geometry type Correspondence – “Atomic” subtype of the Geometry type Correspondence – Collection subtypes of the Geometry type |
| Implementation benefits | ISO 19125-1 specifies a class Geometry with the following subclasses: Point, Curve, Surface and GeometryCollection. Each geometric object is associated with a Spatial Reference System that describes the coordinate space in which the geometric object is defined. ISO 19125-1 also specifies attributes, methods, and assertions with the geometries. However, ISO 19125-1 does not support topology. ISO 19125-1 allows geometric features to be defined that are interoperable and ‘integratable’ with other objects created using the requirements set out in this standard. |
| Products | ISO 19125-1 is popular in web applications where the feature needs to be simple and when topology is not a requirement. GeoJSON and ISO 19136:2007 Geographic information - Geography Markup Language (GML) are examples of implementations of ISO 19125-1. |
