Over the past decade, location data and spatial analytics have played a transformative role in addressing a number of global issues. My interest has focused on improving public health and sustainable communities through improved sharing of geospatial information.

The Power of Location

“Location targeting is the holy grail for marketers.” This statement was directed to an entire industry at Mobile World Congress by Sir Martin Sorrell, CEO of the world's largest advertising company by revenues. While this may be a revelation of a new reality to some, the geographer reading this might be saying, "Where's Waldo?" The so-called first law of geography from Waldo Tobler is "Everything is related to everything else, but near things are more related than distant things.” This was recently validated by analysis of

Is the OGC playing with Linked Data?

Linked Data is about enabling computers to search structured information about “things” over the web. The linking methodology is based on the following Semantic Web principles:

1) Things are uniquely identified using Uniform Resource Identifiers (URIs).

2) Use HTTP (HyperText Transfer Protocol) URIs, to make those things accessible by computer programs.

3) The knowledge of things is expressed using the W3C Resource Description Framework (RDF) and queried via SPARQL.

For the sixth Interoperability Day organized by the French forum of the Open Geospatial Consortium (OGC) in 2012, the Lyon metropolis created a first sample of CityGML data in order to test its integration within different market tools. The program of this experiment is described at: http://www.forumogcfrance.org/journee-interoperabilite/archives-2012/programme-77/

OGC Xlink Policy and timeline to move to XLink 1.1

Back in 2000, the OGC Members determined that the W3C XLink recommendation was well suited to the requirements for GML 2.0 as well as other OGC standards. However, at that time, W3C did not have a XLink schema. Therefore, the OGC Members decided to define an OGC XLink schema that was based on the W3C XLink recommendation. This XLink schema is now used in numerous OGC standards (See below).

Editor’s note:

Earlier this month, Steve Liang, chair of the OGC SensorThings Standards Working Group (SWG) received an email from someone planning to implement the candidate SensorThings API on top of the OpenIoT platform. She wanted to get answers to these questions about SensorThings before coding:
