Data model standards
This group of standards builds on the ISO/TC 211 reference model. The data model standards provide a family of abstract conceptual schemas for describing the fundamental components of features as elements of geographic information.
ISO/TC211 maintains a wiki on best practices for modeling geographic information in UML.
For generic geospatial data
- ISO 19107:2003 Geographic information - Spatial schema, specifies UML classes for representing the spatial characteristics of features as composites of geometric and/or topological primitives.
- ISO 19108:2002 Geographic information - Temporal schema, does the same as ISO 19107 for the temporal characteristics of features and also specifies classes for describing relevant temporal reference systems.
- ISO 19109:2015 Geographic information - Rules for application schema, specifies a general feature model for integrating these components into features and provides rules for doing so in an application schema.
- ISO 19137:2007 Geographic information - Core profile of the spatial schema, provides a profile of ISO 19107 that is limited to describing features as simple geometric primitives of 0, 1, or 2 dimensions.
- ISO 19123:2005 Geographic information - Schema for coverage geometry and functions, provides a schema for an alternative representation of spatial information as a coverage, in which non-spatial attributes are assigned directly to geometric objects rather than to features composed of such objects.
- ISO 19125-1:2004 Geographic information - Simple feature access - Part 1: Common access, describes a common architecture for providing access to information about features with simple geometry.
- ISO 19125-2:2004 Geographic information - Simple feature access - Part 2: SQL option, specifies a Structured Query Language implementation of ISO 19125-1.
- ISO 19141:2008, Geographic information -- Schema for moving features, extends ISO 19107 to support the description of moving geometric objects.
