ISO 19125-1:2004 Geographic information - Simple feature access - Part 1: Common access

Overview

Full name	ISO 19125-1:2004, Geographic information - Simple feature access - Part 1: Common access
Version	Edition 1
Amendments	None
Corrigenda	None
Published by	ISO/TC 211
Languages	English
Online overview	https://www.iso.org/obp/ui/#iso:std:iso:19125:-1:ed-1:v2:en
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.
