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 GML are examples of implementations of ISO 19125-1.
