Remote Sensing Catches Large Antarctic Ice Shelf Breaking Off
Monday, April 6th, 2009
Slashdot ran two stories this weekend, the first one named Large Ice Shelf Expected To Break From Antarctica and later Antarctic Ice Bridge Finally Breaks Off. From the first one: "A large ice shelf is 'imminently' close to breaking away from part of the Antarctic Peninsula, scientists said Friday. Satellite images released by the European Space Agency on Friday [...]". The second summary: " An ice bridge linking a shelf of ice the size of Jamaica to two islands in Antarctica has snapped. Scientists say the collapse could mean the Wilkins Ice Shelf is on the brink of breaking away, and provides further evidence of rapid change in the region. Sited on the western side of the Antarctic Peninsula, the Wilkins shelf has been retreating since the 1990s. Researchers regarded the ice bridge as an important barrier, holding the remnant shelf structure in place. Its removal will allow ice to move more freely between Charcot and Latady islands, into the open ocean." Recent geoblogs related stories are Glacier Melt Survey in Google Earth and New USGS Study Documents Rapid Disappearance of Antarctica’s Ice Shelves. See also numerous related stories below.
The Blue Marble Navigator
Monday, March 30th, 2009
NASA’s Next Generation Blue Marble imagery (available here) is a set of 12 monthly composite images of the entire earth, using 500-meter-resolution imagery from the MODIS satellite. The Blue Marble Navigator offers a convenient interface to view this imagery, along with several other useful options.
After selecting your initial location from a world map, the main [...]

In the spirit of my previous “Big List” series on free GIS programs and free metadata programs comes the Big List Of Satellite/Aerial Imagery Analysis Software. While a few of these programs are general image analysis/manipulation programs, most are specifically designed to primarily deal with some aspect of displaying and analyzing satellite or aerial imagery.

Tuesday, January 20th, 2009As reported by our friends at the Google Lat Long Blog
We just received a spectacular overhead shot of the National Mall during the Inauguration from our satellite imagery partner GeoEye. This gorgeous satellite view of the ceremony was taken at 11:19am (Eastern) by the GeoEye-1 satellite as it passed overhead. To see this amazing image download this KML and open it up in Google Earth -- here is a preview of what you'll see:
A big thanks to GeoEye for capturing this momentous event!
NASA’s Giovanni Remote Sensing Data Tool
Tuesday, January 20th, 2009
Via personal email, I've been informed about NASA's Giovanni remote sensing data tool. From the site: "Giovanni is a Web-based application developed by the GES DISC that provides a simple and intuitive way to visualize, analyze, and access vast amounts of Earth science remote sensing data without having to download the data. Giovanni is comprised of a number of interfaces, called instances, each tailored to meet the needs of different Earth science research communities." The instances are Atmospheric, Environmental, Ocean and Hydrology. There are *many* remote sensing satellite and other datasets supported, see the URL above. I've been told kmz can even be generated with the tool (and doubtlessly several other formats).

USGS & OptIPortal, a Mega LCD Wall, Used in Obama Inauguration Security
Wednesday, January 14th, 2009As reported by our friends at the All Points Blog
With support of the USGS and the University of Illinois-Chicago's (UIC) Electronic Visualization Lab (EVL), security planning for president-elect Obama's inauguration included technology called OptIPortal, a multi-screen, tiled wall of LCD monitors (See image at right where it is being demonstrated to Interior Secretary Dirk Kempthorne [center] and Senator Ken Salazar [right]-click for larger image). From our contacts at UIC..."LambdaVision, GeoWall and OptIPortal--it varies from user group to user group. What's common is that they all consist of tiled LCD displays, run middleware like SAGE to manage the window and stream pixels among the distributed sites, and are connected to 1-10Gbps networks. The OptIPortal used by Interior for the inauguration planning however, was not networked and the content was being managed by software called Magic Carpet."
See the UIC press release as well as more graphics of the OptiPortal display at the SAGE/EVL gallery. (graphics used with permission of UIC)
