Last summer, members of the OGC Technical Committee’s Temporal Domain Working Group (Temporal DWG) had a long and interesting dialog about representation of coordinate reference systems (CRSs), the need for aligned spatial and temporal CRSs, and the eventual need for dynamic datums[1].

2015 The Year in Summary – 2016 The Year Ahead

As we enter the New Year, I want to take this opportunity to summarize some of the accomplishments of the Consortium over the past 12 months, and to provide you with insight into some of the activities envisioned or already underway for 2016. 

2015 proved to be a productive year for the OGC. OGC members advanced a range of new and revised standards and associated best practices of value to the community. Accomplishments include:

Testbed 12 Interoperability Testbed proposals due soon!

The Open Geospatial Consortium (OGC®) issued a Request for Quotations/Call for Participation (RFQ/CFP) in the OGC Testbed 12 Interoperability Testbed on 23 October 2015. Proposals for the Aviation thread are due by 5:00 pm EST on 20 November 2015; proposals for all the other threads are due by 5:00 pm EST on 11 December. This initiative stands to be one of the largest Testbeds conducted in the history of the OGC Interoperability Program (IP). Details about Testbed 12 and the RFQ/CFP are available at the following link:

A retrospective on the OGC Interoperability Program: "Innovation in OGC"

A history of the OGC Interoperability Program was just published the the ISPRS International Journal of GeoInformation (IJGI).  The article was written by the four people who have served as Executive Directors of the program:  Jeff Harrison, Nadine Alameh, Terry Idol and George Percivall.

This is the abstract of the paper:

Interoperability is a major challenge for the Internet of Things (IoT). The real potential of  IoT, like the potential of the Internet itself, lies in “systems of IoT systems” rather than IoT systems that operate as isolated technology silos. Real interoperability requires layers of standards, and each layer addresses different interoperability challenges.

The advent of smartphones and the use of GPS technology has sky-rocketed in recent years. All of us have had the experience, however, of following the directions provided by the device and finding ourselves “not quite” at the destination. This is often because the geo-coordinates accessed by the device are usually rendered by satellite and represent a general approximation of home or business, not necessarily the “front door”.
