Master of Ceremonies, Lewis Graham of GeoCue, opened with his comments on the importance of miniaturization, connectivity and sensors in the UAS market.

“Miniaturization and connectivity and sensors. Sensors will communicate in intelligent ways, software in background to make that happen,” said Graham. In addition, “Sense and avoid” type of technology/ software makes decisions based on proximity of the aerial system.”

The confluence of miniaturization, guidance and control systems, motors, sensors, on the photogrammetry side, new technologies out of robotic vision, taking point clouds of photos and taking information from this all conspire to bring UAS to the forefront and make it a force to be reckoned with.

Images show Chinese air pollution from NASA satellite

Tuesday, January 15th, 2013

Mid-January 2013 air quality proved to be dangerous to the health of Beijing residents and those of many other cities in China. Authorities warned people to stay indoors as the nation faced one of the worst periods of air quality in recent history. Factories were government-ordered to scale back emissions. According to news reports, hospitals experienced more than 20 to 30 percent increase in patients complaining of respiratory issues.

According to NASA Earth Observatory, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired these natural-color images of northeastern China on January 14 (top) and January 3, 2013. The top image shows extensive haze, low clouds, and fog over the region. The brightest areas tend to be clouds or fog, which have a tinge of gray or yellow from the air pollution. Other cloud-free areas have a pall of gray and brown smog that mostly blots out the cities below. In areas where the ground is visible, some of the landscape is covered with lingering snow from storms in recent weeks. (Snow is more prominent in the January 3 image.)

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.
