Utilities workflow in Autodesk Infrastructure Design Suite 2013

Tuesday, April 17th, 2012

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.

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.

Read about why U.S. commercial satellite imagery is important:

“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.

RapidEye imagery used for MALAREO project in southern Africa

Tuesday, March 13th, 2012

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.

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.

Laser radar image of 2010 Mexicali earthquake released

Tuesday, February 14th, 2012

Released by an international team of scientists is a laser-radar image of the area surrounding the site of a Magnitude 7.2 earthquake that occurred in Mexicali, Mexico, in 2010. The laser radar technique can spot surface changes of just a few centimetres; in this image the blue represents a post-quake reduction in height and red indicates an increase.

Drought mapping using measurements obtained from weather and research satellites

Monday, February 13th, 2012

The National Oceanic and Atmospheric Administration’s (NOAA) Center for Climate Prediction holds a monthly drought briefing by teleconference to identify the latest drought areas in North America, according to  Don Comis of the USDA Agricultural Research Service (ARS). ARS scientists, Martha Anderson and Bill Kustas, are hoping that in a year or so, data from their computer model/satellite package will give evapotranspiration (ET) maps a seat at that briefing.
