Directing the Evolution of GEOSS Technical Architecture

Although all GEOSS systems continue to operate within their own mandates, GEOSS systems can leverage each other so that the overall GEOSS becomes much more than the sum of its component systems. This synergy develops as each contributor supports common arrangements designed to make shared observations and products more accessible, comparable, and understandable.” In this opinion editorial, George Percivall, chief architect of the GEOSS Interoperability Program, describes the remarkable progress that GEOSS builders have already made.

The Open Geospatial Consortium (OGC®) issues a Request for Information (RFI)

Satellite image of planet EarthSeeking to establish alliances and share information amongst various Standards Development Organizations (SDOs) with technology relevant to fusion, the Open Geospatial Consortium has issued a Request for Information (RFI). Responses are requested by August 12, 2009 and the RFI includes instructions for how organizations can respond. The information gathered is to be used in preparation of a Fusion Standards Study.

Cropped Google map on www.thishikingtrail.com using the Maps API interface to display locations of hiking trails overlaid on a highway map. Similar maps can be composed using KML.People can now easily visualize what their next trip or hike will look like; they can readily combine EO data with other kinds of geographic data ; and they can easily save the views they have constructed and send them to other users. However, geospatial technologies are more complex than most people realize.

Panorama of the East Coast

Panorama of the East Coast

This Jan. 29 panorama of much of the East Coast, photographed by one of the Expedition 30 crew members aboard the International Space Station, provides a look generally northeastward: Philadelphia-New York City-Boston corridor (bottom-center); western Lake Ontario shoreline with Toronto (left edge); Montreal (near center). An optical illusion in the photo makes the atmospheric limb and light activity from Aurora Borealis appear "intertwined." Image Credit: NASA
