OGC Implementation Specifications

*THIS STANDARD HAS BEEN RETIRED* The OpenGIS® Transducer Markup Language Encoding Standard (TML) is an application and presentation layer communication protocol for exchanging live streaming or archived data to (i.e. control data) and/or sensor data from any sensor system. A sensor system can be one or more sensors, receivers, actuators, transmitters, and processes. A TML client can be capable of handling any TML enabled sensor system without prior knowledge of that system. The protocol contains descriptions of both the sensor data and the sensor system itself. It is scalable, consiste...

In March, 2007 the Open Geospatial Consortium, Inc. (OGC®) membership approved the Geospatial Digital Rights Management Reference Model (GeoDRM RM), an abstract specification for the management of digital rights in the area of geospatial data and services. The GeoDRM RM is Topic 18 of the OpenGIS® Abstract Specification.


The goal of the GeoDRM effort in the OGC is to make sure that a larger market has access to geospatial resources through a well understood and common mechanism that enables more than today's "all or nothing" protection. A major motivation for this effort is the need to manage the "ownership obstacle to data sharing" in spatial data infrastructure scenarios.

The OpenGIS® Web Map Service Interface Standard (WMS) provides a simple HTTP interface for requesting geo-registered map images from one or more distributed geospatial databases. A WMS request defines the geographic layer(s) and area of interest to be processed. The response to the request is one or more geo-registered map images (returned as JPEG, PNG, etc) that can be displayed in a browser application. The interface also supports the ability to specify whether the returned images should be transparent so that layers from multiple servers can be combined or not.

This document specifies how a Web Coverage Service (WCS) offers multi-dimensional coverage data for access over the Internet. This document specifies a core set of requirements that a WCS implementation must fulfill. WCS extension standards add further functionality to this core; some of these are required in addition to the core to obtain a complete implementation. This document indicates which extensions, at a minimum, need to be considered in ad-dition to this core to allow for a complete WCS implementation. This core does not prescribe support for any particular coverage encoding format. ...
