GeoEye and DigitalGlobe plan to merge

Wednesday, July 25th, 2012

In a move that the geospatial industry had been expecting, on Monday, GeoEye announced plans to combine with competitor DigitalGlobe in a deal worth $900 million. This move is in response to the National Geospatial-Intelligence Agency informing both companies that it plans to curtail funding for its $7.3 billion EnhancedView contract, pieces of which were awarded to both firms in 2010.

The two former competitors provide photos and satellite imagery from satellites that are contracted by the NGA, the products of which are generally sold to federal agencies, the military and other government institutions.

Tuesday, April 24th, 2012

ForWarn is a satellite-based forest disturbance monitoring system for the conterminous United States. It delivers new forest change products every eight days and provides tools for attributing abnormalities to insects, disease, wildfire, storms, human development or unusual weather. Archived data provide disturbance tracking across all lands since 2000. Interactive maps are accessible via the Forest Change Assessment Viewer.

The importance of U.S. commercial satellite imagery

Friday, April 13th, 2012

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.

Envisat stops sending data to earth

Friday, April 13th, 2012

After just having celebrated its 10th anniversary of service on 1 March 2012, ESA’s Envisat stopped sending data to earth. The last contact between the satellite and the ground station in Kiruna, Sweden was established on Sunday, ever since no data has been received. ESA’s mission control is working to re-establish contact with the satellite. Launched in 2002, Envisat has orbited Earth more than 50 000 times delivering thousands of images and other data used for example for climate change studies or natural disaster mitigation supporting more than 4000 projects in over 70 countries.

“Change matters” viewer from Esri displays Vegas sprawl

Tuesday, March 13th, 2012

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.

Iranian nuclear facility revealed by GeoEye satellite imagery

Thursday, February 23rd, 2012

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.

Underwater volcanic eruption off El Hierro continues

Wednesday, February 15th, 2012

The underwater volcanic eruption off El Hierro Island continues four months after it began.

Collected on February 10, 2012, this natural color satellite image shows the site of the eruption, near the fishing village of La Restinga. The beautiful aquamarine water indicates high concentrations of volcanic material. Right above the vent a patch of brown water  can resemble a turbulent hot tub when the eruption is strongest.

This image was acquired by the Advanced Land Imager (ALI) aboard the Earth Observing-1 (EO-1) satellite. The eruption is just off the southern coast of El Hierro, the youngest of the Canary Islands. El Hierro is about 460 kilometers (290 miles) west of the coast of Morocco and Western Sahara.

According to El Hierro Digital measurements of the sea floor by the Instituto Oceanográfico Español showed that the volcano’s summit is now only 120 meters (390 feet) beneath the ocean surface—10 meters (30 feet) higher than it was in mid January. The height of the erupting cone is about 210 meters (690 feet) from the former ocean bottom, with a total volume over 145 million cubic meters (512 million cubic feet) of new material.
