The Heterogeneous Missions Accessibility (HMA) manual , freely downloadable from the ESA web site , provides a high level view on the results of several years of harmonisation and standardisation work in the critical area of ground segment interoperability of Earth Observation satellite missions. The coordinated effort of the European space and downstream industries, research centres, agencies and institutions has made a significant contribution to the definition of geospatial standards published within the Open Geospatial Consortium. Earth Observation systems are inherently
A new standard being developed in the OGC has an important part in improving shared situational awareness. The candidate OGC Web Services (OWS) Context standard encodes the key elements of a common operating picture: the geographic area, an optional time range, and an ordered series of layers from different services or inline content. This allows a situational awareness view of one user to be passed to other users so that the same picture can be reconstructed.
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.
In last week's OGC TC meeting in Brussels, I gave a talk in the Mass Market Domain Working Group which mentioned funding that our project received from the Taiwan government, collaborations with Ushahidi and Sahana, and the Samoa Cyclone Simulation. Here is the presentation (19.6MB).
“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
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.
