Abstract Specifications
The OGC Technical Committee (TC) has developed an architecture in support of its vision of geospatial technology and data interoperability called the OGC Abstract Specification. The Abstract Specification provides the conceptual foundation for most OGC specification development activities. Open interfaces and protocols are built and referenced against the Abstract Specification, thus enabling interoperability between different brands and different kinds of spatial processing systems. The Abstract Specification provides a reference model for the development of OGC Implementation Standards.

1.0 | 10-020 | Paul Cooper | 2014-04-16 |
Topic 3 - Locational Geometry Structures | 4.0 | 99-103 | Cliff Kottman | 1999-03-18 |
Provides essential and abstract models for GIS technology that is widely used. | ||||
Topic 4 - Stored Functions and Interpolation | 4.0 | 99-104 | Cliff Kottman | 1999-03-30 |
This Topic Volume provides essential and abstract models for technology that is used widely across the GIS landscape. Its first heavy use is expected to occur in support of Coverage specifications (see Topic 6, The Coverage Type). | ||||
Topic 5 - Features | 5.0 | 08-126 | Cliff Kottman and Carl Reed | 2009-01-15 |
From ISO 19101, “A feature is an abstraction of a real world phenomenon”; it is a geographic feature if it is associated with a location relative to the Earth. | ||||
Topic 6 - Schema for coverage geometry and functions | 7.0 | 07-011 | OGC | 2007-12-28 |
This International Standard defines a conceptual schema for the spatial characteristics of coverages. Coverages support mapping from a spatial, temporal or spatiotemporal domain to feature attribute values where feature attribute types are common to all geographic positions within the domain. A coverage domain consists of a collection of direct positions in a coordinate space that may be defined in terms of up to three spatial dimensions as well as a temporal dimension. | ||||
Topic 7 - Earth Imagery | 5.0 | 04-107 | George Percivall | 2004-10-15 |
Replaced previous material in Topic 7 with ISO 19101-2, Reference Model - Geographic Information - Imagery. Version 5 of OGC Topic 7 is identical with ISO 19101-2 Working Draft #3. Topic 7 will be updated jointly with the progress of ISO 19191-2. Appendix A of Topic 7, version 4 contained a "White Paper on Earth Image Geometry Models." That white paper is now separate OGC Recommendation document. | ||||
Topic 8 - Relationships Between Features | 4.0 | 99-108r2 | Cliff Kottman | 1999-03-26 |
This Topic introduces an abstraction for the relationships between entities in the real world. This abstraction is modeled as relationships between the features introduced in Topic 5. | ||||
Topic 10 - Feature Collections | 4.0 | 99-110 | Cliff Kottman | 1999-04-07 |
An OpenGIS Feature Collection is an abstract object consisting of Feature Instances, their Feature Schema, and Project Schema. | ||||
Topic 11 - Metadata | 11-111r1 | ISO | 2016-09-16 | |
Same as ISO 19115-1:2014. Abstract Specification Topic 11 was updated to the latest version of the ISO metadata standard on 21 September 2016. Prior to this date, this Topic was the same as ISO 19115:2003. Please note that many OGC standards and other related work normatively refer to the previous version of this Topic. | ||||
Topic 12 - The OpenGIS Service Architecture | 4.3 | 02-112 | ISO | 2001-09-14 |
Same as ISO 19119 | ||||
Topic 13 - Catalog Services | 4.0 | 99-113 | Cliff Kottman | 1999-03-31 |
Covers the Geospatial Information Access Services | ||||
Topic 14 - Semantics and Information Communities | 4.0 | 99-114 | Cliff Kottman | 1999-04-04 |
The OpenGIS notion of Information Communities was devised to enable groups such as ecologists and civil engineers to efficiently manage the semantics (or feature schema mismatches) of their own geodata collections and get maximum benefit from each other's geodata collections, despite semantic differences. | ||||
Topic 15 - Image Exploitation Services | 6.0 | 00-115 | Cliff Kottman, Arliss Whiteside | 2000-04-24 |

Topic 18 - Geospatial Digital Rights Management Reference Model (GeoDRM RM) | 1.0.0 | 06-004r4 | Graham Vowles | 2007-01-29 |
This document is a reference model for digital rights management (DRM) functionality for geospatial resources (GeoDRM). As such, it is connected to the general DRM market in that geospatial resources must be treated as nearly as possible like other digital resources, such as music, text, or services. It is not the intention here to reinvent a market that already exists and is thriving, but to make sure that a larger market has access to geospatial resources through a mechanism that it understands and that is similar to the ones already in use. | ||||
Topic 19: Geographic information - Linear referencing | 2012 | 10-030 | Paul Scarponcini | 2012-03-20 |
Same as ISO IS 19148: 2012. Download at http://www.iso.org | ||||
Topic 20: Observations and Measurements | 2.0 | 10-004r3 | Simon Cox | 2010-11-10 |
This International Standard defines a conceptual schema for observations, and for features involved in sampling when making observations. These provide models for the exchange of information describing observation acts and their results, both within and between different scientific and technical communities. Observations commonly involve sampling of an ultimate feature of interest. This International Standard defines a common set of sampling feature types classified primarily by topological dimension, as well as samples for ex-situ observations. The schema includes relationships between sampling features (sub-sampling, derived samples). This International Standard concerns only externally visible interfaces and places no restriction on the underlying implementations other than what is needed to satisfy the interface specifications in the actual situation. | ||||
