17 November 2014 - The membership of the Open Geospatial Consortium (OGC®) seeks public comment on the candidate Earth Observation Metadata Profile of the OGC Observations and Measurements (O&M) Standard.

The Earth Observation (EO) Metadata profile of Observations and Measurements is intended to provide a standard schema for encoding Earth Observation product metadata to support the description and cataloguing of products acquired by sensors aboard EO satellites.

EO products are differentiated by parameters such as the date of acquisition and the image footprint as well as characteristics pertaining to the type of sensor, the type of platform, the applied processing chain, and more. This candidate standard identifies the metadata elements that enable the robust description of general EO products and defines specialisations for specific thematic classes of EO products, such as optical, radar, atmospheric, altimetry, limb-looking and systematic/synthesized EO products. In addition, this document describes the mechanism used to extend these thematic schemas for specific EO missions.

Version 1.0 of the EO Metadata profile of O&M is an OGC Implementation Standard that was adopted in 2012. Since then the standard has been implemented by the EO ground segments of a number of EO missions. During these implementations, a number of improvements and corrections have been identified. The proposed version 1.1 addresses these corrections and improvements.

The documents for the candidate OGC Earth Observation Metadata profile of Observations & Measurements Standard are available for review and comment at (http://www.opengeospatial.org/standards/requests/127).

The OGC is an international consortium of more than 495 companies, government agencies, research organizations, and universities participating in a consensus process to develop publicly available geospatial standards. OGC Standards support interoperable solutions that "geo-enable" the Web, wireless and location-based services, and mainstream IT. OGC Standards empower technology developers to make geospatial information and services accessible and useful with any application that needs to be geospatially enabled.

November 13, 2014 - Join the Group on Earth Observations (GEO), the Open Geospatial Consortium (OGC) and invited speakers at a special joint session scheduled for  December 1st, 1100-1800 (JST), in Tokyo, Japan.

The session is intended to provide an overview and discussion on the state of the Group on Earth Observations System of Systems (GEOSS) and the role of OGC and other standards to enable greater interoperability in the context of Asia, with a particular focus on GEO plans for the next ten years.

Co-located with OGC’s December technical and planning committee meetings (OGC-TC/PC), speakers will present on a variety of topics including:

  • Introduction to the Group on Earth Observation GEO/GEOSS and the  Role of the Infrastructure Implementation Board (IIB) and the GEOSS Common Infrastructure (GCI)
  • OGC’s role in GEO - Results from the Architectural Implementation Pilot
  • The Vision and Architecture for the GEOSS Information System future products and services
  • The OGC Technical Committee Opening Plenary - A unique invitation to learn more about the OGC community
  • Asia and GEO - Asian organisations, both GEO members and non-members, will present on relevant topics
  • The Geneva Plenary and the GEO Strategic Plan (2106-2025) - A Review of Outcomes from the November Geo Plenary
  • Panel Discussion - GEO and Asian Organisations; how do we increase participation?
  • This is a free event but registration is required. Space is limited and you are encouraged to register as soon as possible.

Event: The Group on Earth Observations and the System of Systems in Asia; the Next 10 years

Date and Time: December 1st, 1100-1800 (JST)

Location: Tokyo, Japan

Venue: Akiharaba Convention Hall (5th Floor), Tokyo, Room 5C-2

Registration Link: http://www.eventbrite.com/e/geo-ogc-joint-session-tickets-14201024647

OGC announces KML 2.2 Test Suite

Release Date: 
2014-11-07

Content: 

7 November 2014. The Open Geospatial Consortium (OGC®) has announced that the OGC Members approved the KML 2.2 validator as part of the official OGC Compliance Testing Facility. The validator tests whether implementations are correctly publishing KML data. The validator tests KML and KMZ files, located locally or available via a URL.

KML is an XML language focused on geographic visualization, including annotation of maps and images. KML is supported in numerous Earth browser applications and geospatial software products. About 70 KML 2.2 implementations are registered in the OGC implementations database. In early 2010, Google submitted KML to the Open Geospatial Consortium (OGC) to be maintained and evolved within the OGC consensus process.

The test suite is based on the KML Abstract Test Suite [2] and is structured in 3 levels:

  • Level 1 - includes test cases covering requirements that must be satisfied by a minimally conformant KML document;
  • Level 2 - same as Level 1, plus test cases addressing recommended constraints;
  • Level 3 - same as Level 2, plus test cases covering suggested constraints that are informative in nature.

 

Organizations can test their KML instances (KML or KMZ) at no cost at the OGC Testing Facility. If an organization’s implementation successfully passes the KML test, then the organization can receive OGC certification for their KML implementation by following a simple procedure.

The OGC acknowledges the support of Even Rouault for developing the reference implementation GDAL libkml and the support of Richard Martell from Galdos for developing the test suite.
