OGC Implementation Specifications

GML in JPEG 2000 for Geographic Imagery Encoding

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 ...

Grid Coverage Service

**This document has been retired.  It is not supported.  You should consider using Web Coverage Service.**

The OpenGIS® Grid Coverage Service Implementation Specification defines methods that allow interoperability between software implementations by data vendors and software vendors providing grid (raster) analysis and processing capabilities.


Google submitted KML (formerly Keyhole Markup Language) to the Open Geospatial Consortium (OGC) to be evolved within the OGC consensus process with the following goal: KML Version 2.2 has been adopted as an OGC implementation standard. Future versions may be harmonized with relevant OGC standards that comprise the OGC standards baseline. There are four objectives for this standards work:

  • That there be one international standard language for expressing geographic annotation and visualization on existing or future web-based online and mobile maps (2d) and earth browsers (3d)....

Location Service (OpenLS)

The OpenGIS® Open Location Services Interface Standard (OpenLS) specifies interfaces that enable companies in the Location Based Services (LBS) value chain to “hook up” and provide their pieces of applications such as emergency response (E-911, for example), personal navigator, traffic information service, proximity service, location recall, mobile field service, travel directions, restaurant finder, corporate asset locator, concierge, routing, vector map portrayal and interaction, friend finder, and geography voice-graphics. These applications are enabled by interfaces that implement OpenLS s...

OGC network Common Data Form (netCDF) standards suite

netCDF is a set of software libraries and self-describing, machine-independent data formats that support the creation, access, and sharing of array-oriented scientific data. The conventions for climate and forecast (CF) metadata are designed to promote the processing and sharing of netCDF files. The conventions define metadata that provide a definitive description of what the data represents, and the spatial and temporal properties of the data.

The OGC CF-netCDF standard consists of a suite of standards that support encoding of digital geospatial information representing space/ti...

OGC Web Services Context Document (OWS Context)

This standard describes the use cases, requirements and conceptual model for the OWS Context encoding standard. The goal of this standard is to provide a core model, which is extended and encoded as defined in extensions to this standard. A ‘context document’ specifies a fully configured service set which can be exchanged (with a consistent interpretation) among clients supporting the standard. The OGC Web Services Context Document (OWS Context) was created to allow a set of configured information resources (service set) to be passed between applications primarily as a collection of serv...
