Last week I attended the workshop “Connecting Grassroots to Government for Disaster Management” at the Woodrow Wilson International Center for Scholars. This was my first meeting I have attended that was fully dedicated to the discussion of Volunteered Geographic Information (VGI). Lea Shanley, director of the Commons Lab, brought together top-notch panelists (see agenda) from government, university and industry. A great variety of topics were

I attended the second day at the 2012 Air Transportation Information Exchange Conference, at NOAA in Silver Spring (See Nadine's related blog here). The first three talks were focused on semantics. Then my colleague Nadine Alameh gave a rich multimedia overview (70 Mb presentation) about OGC and OGC Web Services activities (OWS). I talked about the semantic work being advanced in OWS.
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.
I was really happy to see all the excitement about OGC standards at MundoGeo Meeting in Sao Paulo, Brazil last week. My keynote presentation had a lot in common with other speakers, emphasizing the need and challenges of making available more current geospatial data. These includes data that has been changed due to natural disasters and data merged with new technologies.
Brazil exports airplanes to France. Colombia exports coffee and cotton. Other countries in South America lead in other industries and markets, but not yet in Geospatial Standards. Standards, which are formal agreements published by a standard organization, are the prime material of Spatial Data Infrastructures. Currently these come mostly from brainpower and requirements from Europe and the US. OGC has about 30 domain groups and 40 standard working groups. People from 450 organizations form these working groups. But, how many organizations in South America are OGC members? Only one.
OGC develops and publishes open standards not only for maps and geospatial analysis but also to help us share real time observed data from sensors. There is a very important activity within OGC called
