Karymsky Volcano has erupted regularly for more than ten years. This natural-color satellite image shows the volcano’s typical low-level activity. A white gas plume rises above Karmymsky’s summit, and fresh volcanic material coats the eastern slopes. This image was acquired by the Advanced Land Imager (ALI) aboard theEarth Observing -1 (EO-1) satellite on May 3, 2012.

On Friday, May 4, GeoEye held an investor webcast announcing that it proposes to acquire DigitalGlobe, Inc., seen by DigitalGlobe as a “public hostile offer.” The combination of these two satellite imaging companies would form the world’s largest fleet of high resolution commercial imagery satellites, according to GeoEye.
Matt O’Connell CEO and President of GeoEye, said that the two companies combined would result in “greater capabilities to meet national security needs, be more cost effective to the U.S. government during a fiscally restrained period, improve value to decision makers, warfighters and shareholders.”
A quick overview of the proposed acquisition: DigitalGlobe shareholders will receive $17.00 per share in total consideration, payable $8.50 per share in cash and $8.50 in GeoEye stock, or 0.3537 shares of GeoEye stock for each share of DigitalGlobe stock. This price represents a 26% premium to DigitalGlobe’s closing share price on May 3, 2012. According to O’Connell, the proposal is structured to provide DigitalGlobe shareholders with the opportunity to participate in the dynamic future growth of the combined company.
Jeff Culwell vice president of operations, DigitalGlobe talked about what led up to their anticipated WorldView-3 satellite and the details about it. The satellite is slated for launch in mid-2014. The announcement was made at the 28th Annual National Space Symposium.
While Autodesk does not talk about GIS much these days, embedded in their Autodesk Infrastructure Design Suite 2013 is a Utilities Workflow that offers intelligent model based software for meeting the complex needs of the SmartGrid, with GIS products built in. The emphasis appears to be on helping transform planning, design and management processes by capturing conditions at the start of the design process, useful for both designers and GIS professionals.
High resolution imagery of sub-meter – less than 40 inches – is only available from GeoEye, DigitalGlobe, Astrium Geo, and ImageSat. It is what the stuff of Google is made of. GeoEye and DigitalGlobe represent approximately 75% of this market, and 2/3 of their revenue is tied to the U.S. government. There are lots of free, government sources of satellite imagery like Landsat, and weather satellites from NASA and NOAA, but these are not high-resolution satellites that can zoom in on your house, or support 3D modeling for engineering and virtual reality-type applications.

The Change Matters viewer from Esri can show how your area has changed over a given time period, say for instance, from 1988 to 1990. Las Vegas is known for its phenomenal sprawl over the past four decades. Time-lapseimages from the Landsat earth monitoring satellites reveal in false-color, multispectral imagery how urban sprawl has stretched out from Nevada’s “Sin City” over the past four decades.
This latest video was posted by NASA in honor of the 28th anniversary of Landsat 5’s launch on March 1, but the pictures actually go back to 1972, when the Landsat program began.
RapidEye announced that its imagery is being used by the MALAREO project help with malaria control programs in countries in southern Africa. Basically, the satellite is mapping the habitats of mosquitoes, which are generally considered malaria risk area. Funded by the European Commission under FP7, the MALAREO project is a mixed European-African consortium that embodies many years of malaria control expertise with the Global Monitoring for Environment and Security (GMES) EO Capacity.
The MALAREO study area in South Africa, Swaziland and Mozambique is approximately 25,000 square kilometers that RapidEye data provided via the EC/ESA GMES Space Component Data Access (GSC-DA). Over five different days between July 18 and November 10, 2011, the data was gathered with total cloud cover of less than one percent. RSS – Remote Sensing Solutions GmbH, partner in the project consortium, is responsible for data processing and the development of Earth Observation (EO) products.
This one-meter resolution satellite image by of Harrisburg, Illinois, by GeoEye was collected March 1, 2012, just one day after a Level 4 tornado touched down on February 29, 2012.
Jeff Peters, Director Federal Programs for Esri spoke with GISCafe’s Sanjay Gangal at the recent Esri Federal GIS Conference in Washington, D. C.
It is a little frightening to be able to identify by satellite imagery a hidden nuclear facility in Iran. Iranian President Mahmoud Ahmadinejad said the facility was for “uranium enrichment” and was 18 months away from being operational. Satellite imagery company GeoEye has released a photo of what it says is this controversial and underground Iranian uranium enrichment site that was identified a week ago.
