Geospatial Current Status

This page summarizes the relationships among specifications, whether they are finished standards or drafts. Below, each title links to the most recent version of a document.

Completed Work

W3C Recommendations have been reviewed by W3C Members, by software developers, and by other W3C groups and interested parties, and are endorsed by the Director as Web Standards. Learn more about the W3C Recommendation Track.

Group Notes are not standards and do not have the same level of W3C endorsement.

Standards

2016-11-08

Geolocation API Specification 2nd Edition

This specification defines an API that provides Web pages scripted access to geographical location information associated with the hosting device.

Group Notes

Overview of the CoverageJSON format

This Note describes CoverageJSON, a data format for describing "coverage" data in JavaScript Object Notation (JSON), and provides an overview of its design and capabilities. The primary intended purpose of the format is to enable data transfer between servers and web browsers, to support the development of interactive, data-driven web applications.

Spatial Data on the Web Best Practices

This document advises on best practices related to the publication and usage of spatial data on the Web; the use of Web technologies as they may be applied to location. The best practices are intended for practitioners, including Web developers and geospatial experts, and are compiled based on evidence of real-world application.

QB4ST: RDF Data Cube extensions for spatio-temporal components

An extension to the RDF Data Cube ontology to support specification of key metadata required to interpret spatio-temporal data. QB4ST provides generalized support for numeric and other ordered references systems, particularly Spatial Reference Systems and Temporal Reference Systems.

Publishing and Using Earth Observation Data with the RDF Data Cube and the Discrete Global Grid System

This document shows how dense geospatial raster data can be represented using the W3C RDF Data Cube ontology in concert with other popular ontologies. SPARQL queries can then be served through an OGC Discrete Global Grid System for observations, coupled with a triple store for observational metadata.

Drafts

Below are draft documents: Candidate Recommendations, other Working Drafts . Some of these may become Web Standards through the W3C Recommendation Track process. Others may be published as Group Notes or become obsolete specifications.

Candidate Recommendations

2017-07-11

Semantic Sensor Network Ontology

The Semantic Sensor Network Ontology (commonly known as "SSN" is an ontology for describing sensors and the observations they make of the physical world. SSN is published in a modular architecture that supports the judicious use of "just enough" ontology for diverse applications, including satellite imagery, large scale scientific monitoring, industrial and household infrastructure, citizen observers, and Web of Things.

Other Working Drafts

2011-05-12

Points of Interest Core

The Points of Interest Core describes a data model and XML syntax for representing information about points of interest on the World Wide Web.

Obsolete Specifications

These specifications have either been superseded by others, or have been abandoned. They remain available for archival purposes, but are not intended to be used.

Retired

2017-07-06

Geolocation API Specification Level 2

This specification adds the ability to retrieve a civic address, rather than coordinates, to the Geolocation API.

2017-05-30

DeviceOrientation Event Specification

This specification defines several new DOM event types that provide information about the physical orientation and motion of a hosting device.

2017-05-30

Geofencing API

This specification defines an API that lets webapps setup geographic boundaries around specific locations and then receive notifications when the hosting device enters or leaves those areas.
