There are several levels of There are several levels of Implementation SpecificationsImplementation Specifications

• Approved Implementation Specifications are completed specifications that have been approved by the consensus of the OGC membership and been published on the OGC public web site.

• Candidate Implementation Specifications are specifications that are moving through the formal OGC approval process but have not yet been formally adopted. A Candidate Implementation Specification can exist as a Discussion Paper for public review, a Recommendation Paper, or a Draft Specification, such as an RFC, that an OGC Technical Committee Special Interest Group (SIG) has begun to review.

• Planned Implementation Specifications are specifications that are formally supported by OGC member resources and are scheduled or are in work as part of OGC’s Interoperability or Specification programs. However, these planned specifications have not yet been documented. Planned specifications are not described in detail here. For information about planned specifications in a particular technology area, contact the chair of the relevant OGC Technical Committee SIG.

Adopted Specifications (1)Adopted Specifications (1)

Specification Name Description

Simple Features – OLE/COM v1.1

The Simple Feature Specification application programming interfaces (APIs) provide for publishing, storage, access, and simple operations on Simple Features (point, line, polygon, multi-point, etc).

Simple Features – CORBA v1.0


Simple Features – SQL v1.1


Web Map Server v1.1.1 Provides four protocols (GetCapabilities, GetMap, GetFeatureInfo and DescribeLayer) in support of the creation and display of registered and superimposed map-like views of information that come simultaneously from multiple sources that are both remote and heterogeneous.




Coordinate Transformation v1.0

Provides interfaces for general positioning, coordinate systems, and coordinate transformations.

Catalog v1.0 Defines a common interface that enables diverse but conformant applications to perform discovery, browse and query operations against distributed and potentially heterogeneous catalog servers.

GML v2.1 The Geography Markup Language (GML) is an XML encoding for the transport and storage of geographic information, including both the geometry and properties of geographic features.

Grid Coverages v1.0 This specification was designed to promote interoperability between software implementations by data vendors and software vendors providing grid analysis and processing capabilities.




Web Feature Server (WFS)

The purpose of the Web Feature Server Interface Specification (WFS) is to describe data manipulation operations on OpenGIS® Simple Features (feature instances) such that servers and clients can “communicate” at the feature level.

Filter Encoding A filter is a construct used to describe constraints on properties of a feature class for the purpose of identifying a subset of feature instances to be operated upon in some way.


Draft and Planned Specifications (1)Draft and Planned Specifications (1)


Web Coverage Server Extends the Web Map Server (WMS) interface to allow access to geospatial "coverages" that represent values or properties of geographic locations, rather than WMS generated maps (pictures).

CT Definition Data for Coordinate Reference

A data model for coordinate reference systems to provide a common framework across all OGC specifications.

Units of Measure Recommendation

Common semantic for units of measurement to be used across all OGC specifications.

Feature Geometry RFP Addresses a portion of the Open Geodata Model dealing with feature geometry objects and collections of feature geometry objects, including their attendant spatial referencing, positional geometries, shapes, ranges, and value mappings.




Geocoder Geocoding is the process of linking words, terms and codes found in a text string to their applicable geospatial features, with known locations. (Locations are defined as geometry; usually points with x, y coordinates.)

Gazetteer An authority for place names. Returns their associated geometries

Geoparser Geoparsing refers to the capability to process a textual document and identify key words and phrases that have a spatial context.

Location Organizer Folder (LOF)

The Location Organizer Folder (LOF) is a GML document that provides a structure for organizing the information related to a particular event or events of interest.




Web Services Architecture

Describes a reference architecture for web services ans is based on ISO TC211 services architecture as found in ISO 19119 Geographic Information – Services.

Web Service Registry A Registry Service defines a common mechanism to classify, register, describe, search, maintain and access information about OGC Web resources. The OGC Service Registry provides the methods for managing a repository; a Registry Client is an application used to access the Registry.




Stateless Catalog A stateless catalog allows clients to invoke arbitrary catalog services without reference to previous invocations.

Style Layer Descriptor The SLD is an encoding for how the Web Map Server (WMS 1.0 & 1.1) specification can be extended to allow user-defined symbolization of feature data.

XML for Image and map Annotation (XIMA)

Defines an XML vocabulary to encode annotations on imagery, maps, and other geospatial data. This vocabulary draws on the Geography Markup Language (OpenGIS® GML)

Web Terrain Server (WTS)

The Web Terrain Server (WTS) produces perspective views of georeferenced data – typically 3-dimensional coverages.



Specification Name

Description

General Services Model

The objective of the OGC General Services Model (GSM) is to detail how geospatial software can plug into broader interoperability infrastructures to use and extend diverse, loosely coupled sources of data and services.

SensorML The Sensor Model Language work proposes an XML schema for describing the geometric, dynamic, and observational characteristics of sensor types and instances.

Coverage Portrayal Service

The Coverage Portrayal Service (CPS) IPR proposes a standard interface for producing visual pictures from coverage data.

Sensor Collection Service

The basic function of the Sensor Collection Service (SCS) is to provide a web-enabled interface to a sensor, collection of sensors or sensor proxy. Sensors are defined as devices that measure physical quantities.

Sensor Model The Sensor Model work proposes an architecture specification for OpenGIS Web-enabled Sensors and related Services.


OLS Draft and Planned Interfaces (1)OLS Draft and Planned Interfaces (1)

Interface Name Description

Directory Service This service provides subscribers with access to an online directory to find the nearest or a specific place, product or service. Given the formulated request, the Directory Service searches the appropriate online directory to fulfill the request

Gateway Service This is the interface between the GeoMobility Server and Location Server through which OpenLS services obtain position data for Mobile Terminals. This interface is modeled after the MLP specified in LIF 1.1 and LIF 2.0 for Standard Location Immediate Service.

Location Utility Service (Geocoder/ Reverse Geocoder)

This service performs as a geocoder by determining a geographic position, given a place name, street address or postal code. The service also performs as a reverse geocoder by determining a complete, normalized place name/street address/postal code, given a geographic position.

Presentation Service This service renders geographic information for display on a Mobile Terminal.

Route Determination Service

This service determines a route for a subscriber

Geocoder DCIS as a Discussion Paper

01-026r1

Geocoder will be undergoing intensive further work as part of the OpenLS initiative. The Geocoder editor is working closely with the GML editor as well as with an addressing/geocoding expert. This interface will be heavily exercised in OpenLS.

Gazetteer DCIS as a Discussion Paper

01-036/0.9

The interface has been pretty stable for a while now, waiting on resolution of some basic WFS issues:1. How to advertise that the data type is actually a gazetteer (DescribeFeature only gives you a local copy of the schema with no way of knowing what it might mean)2. How to query across feature relationships.

Geoparser DCIS as a Discussion Paper

01-035

This is an emerging specification.Work needed is: . Extending the input to cover html and xml. . Fixing the transaction model for inserting/updating vocabularies (needs locking) . The schemas inherit from schemas for WFS, which are now changing. So bring that into synch. . Add information about exceptions.
