The purpose of these specifications is to describe interfaces to allow GIS software engineers to develop applications that expose funct...

The OpenGIS® GML in JPEG 2000 for Geographic Imagery Encoding Standard defines the means by which the OpenGIS® Geography Markup Language (GML) Standard [http://www.opengeospatial.org/standards/gml] is used within JPEG 2000 [www.jpeg.org/jpeg2000/] images for geographic imagery. The standard also provides packaging mechanisms for including GML within JPEG 2000 data files and specific GML application schemas to support the encoding of images within JPEG 2000 data files. JPEG 2000 is a wavelet-based image compression standard that provides the ability to include XML data for description of the ...
The OpenGIS® Geography Markup Language Encoding Standard (GML) The Geography Markup Language (GML) is an XML grammar for expressing geographical features. GML serves as a modeling language for geographic systems as well as an open interchange format for geographic transactions on the Internet. As with most XML based grammars, there are two parts to the grammar – the schema that describes the document and the instance document that contains the actual data. A GML document is described using a GML Schema. This allows users and developers to describe generic geographic data sets that contain poi...
This jointly developed OGC and ISO TC/211 International Standard describes an XML and KVP encoding of a system neutral syntax for expressing projections, selection and sorting clauses collectively called a query expression. These components are modular and intended to be used together or individually by other standards which reference this International Standard.
The OpenGIS® Coordinate Transformation Service Standard (CT) provides a standard way for software to specify and access coordinate transformation services for use on specified spatial data. This standard addresses a key requirement for overlaying views of geodata (“maps”) from diverse sources: the ability to perform coordinate transformation in such a way that all spatial data are defined relative to the same spatial reference system.

Implementation Specifications are different from the Abstract Specification. They are written for a more technical audience and detail the interface structure between software components. An interface specification is considered to be at the implementation level of detail if, when implemented by two different software engineers in ignorance of each other, the resulting components plug and play with each other at that interface.

Any Schemas (xsd, xslt, etc) that support an approved Implementation Specification can be found in the official OGC Schema Repository.

Documents that present technology issues being considered in the Working Groups of the Open Geospatial Consortium Technical Committee. Their purpose is to create discussion in the geospatial information industry on a specific topic. These papers do not represent the official position of the Open Geospatial Consortium nor of the OGC Technical Committee. Schemas for some of these documents can be at the Discussion Paper Schema Repository.

Imagery Metadata  1.0  05-015  Barry Schlesinger  2005-01-27
Special XML schemas have been created for individual data sets, based on ISO 19115 and a general schema for the RSE. However, a generalized metadata XML schema should be available where possible; it should not be necessary to create special schemas for each data set. ISO 19139 can serve as such a general XML implementation specification for 19115. This implementation needs to be tested in practice. In addition, the new ISO standards are incorporating much, if not all, of the metadata not in 19115 that the RSE contain. XML schemas for these metadata need to be developed that are based upon the abstract model in the ISO standards. All of these implementations need to be tested in practice. This Report describes such tests and the results. It also describes to what extent metadata on which the test metadata are based are supported by 19139, to what extent they are supported by metadata specified in the new ISO standards or the RSE, and to what extent new metadata elements are needed.

OpenGIS® Sensor Event Service Interface Specification  0.3.0  08-133  Johannes Echterhoff, Thomas Everding  2008-10-10
The Sensor Event Service (SES) provides operations to register sensors at the service application and let clients subscribe for observations available at the service. The service performs filtering of sensor data (streams) based upon the filter criteria defined in these subscriptions. Filters can be applied on single observations but also on observation streams, potentially aggregating observations into higher-level information (which itself can be regarded as observation data). Whenever matches are discovered, a notification is sent to the subscriber, using asynchronous, push-based communication mechanisms.

It specifies discovery operations, query operations and transaction operations. Discovery operations allow the service to be interrogated to determine its capabilities and to retrieve the application schema that defines the feature types that the service offers. Retrieval operations allow features to be retrieved from the opaque underlying data store based upon constraints on spatial and non-spatial feature properties defined by the client. Transaction operations allow features to be created, changed and deleted from the opaque underlying data store.

OWS Messaging Framework  0.0.3  03-029  Stephane Fellah, Steven Keens  2003-01-20
This document defines a messaging framework to conduct communications between the OGC web services. It is independent of any transport protocol and any messaging encoding. By using the framework, the service designer could focus only on the message definitions and messaging flows for every action supported by the service, without worry on the messaging transport and delivery. The framework should considerably simplify the implementations of the OGC web services and should enable service chaining.

Some image geometry models  1  04-071  Arliss Whiteside  2004-10-04
This discussion paper contains the material that is still relevant from Section 6 (or Appendix A) of the previous version 4 (document OGC 99-107) of OGC Abstract Specification Topic 7, titled "The Earth Imagery Case". That version of Topic 7 has now been superseded by a new version with the same title. In addition, some terminology has been revised to be consistent with the terminology now used in Topic 16: Image Coordinate Transformation Services. Specifically, the previous term "real-time image geometry model" has been changed to "approximate image geometry model". Also, the previous name "Universal Real-Time Image Geometry Model" has been changed to "Universal Image Geometry Model".

Web 3D Service  0.3.0  05-019  Udo Quadt, Thomas Kolbe  2005-02-02
The Web 3D Service is a portrayal service for three-dimensional geodata, delivering graphical elements from a given geographical area. In contrast to the OGC Web Mapping service (WMS) and the OGC Web terrain service (WTS) 3D scene graphs are produced. These scene graphs will be rendered by the client and can interactively be explored by the user. The W3DS merges different types (layers) of 3D data in one scene graph.
Web Coordinate Transformation Service  0.4.0  07-055r1  Arliss Whiteside, Markus U. M  2007-10-09

Web Coverage Service (WCS) 1.1 extension for CF-netCDF 3.0 encoding  0.2.2  09-018  Ben Domenico, Stefano Nativi  2009-04-08
This extension of the WCS standard specifies an Information Community data model with the related encoding that may optionally be implemented by WCS servers. This extension specification allows clients to evaluate, request and use data encoded in CF-netCDF3 format from a WCS server. This document is an extension of the Web Coverage Service (WCS) 1.1 Corrigendum 2 (version 1.1.2) Implementation Standard [OGC 07-067r5]. With small changes, this extension is expected to also apply to WCS 1.2.
Web Image Classification Service (WICS)  0.3.3  05-017  Wenli Yang, Arliss Whiteside  2005-02-10
The Web Image Classification Service (WICS) supports classification of digital images. A digital image is composed of pixel values organized into one or more two-dimensional arrays. The two dimensions of an image represent two axes in space based on a spatial coordinate reference system. The dimensions of the different 2-D arrays comprising an image must be the same and represent exactly the same spatial locations.
