Merrick’s Quality Control module automates compliance for LiDAR point cloud datasets

Tuesday, March 5th, 2013

Bill Emison, senior account manager for Geospatial Solutions at Merrick & Company, talked about their new QC module in Version 7.1 MARS (Advanced Remote Sensing Software).

Airborne LiDAR – urban area

Merrick Advanced Remote Sensing (MARS software suite is a comprehensive, production-grade Windows application designed to visualize, manage, process and analyze LiDAR point cloud data.

The Quality Control module is designed to provide an automated tool for verifying compliance of a LiDAR point cloud dataset to the LiDAR Base Specification Version 1.0 from the USGS (U.S. Geological Survey). The application sits on top of MARS as an extension.

“As a data vendor there have been many contracts where we’ve had to comply to those specs, and in an effort to do that effectively, we started to build tools two-three years ago,” said Emison. “We competely automated the entire specs. Our goal is to deliver data one time and not have to do rework, it was important to identify issues before the dataset went out the door.”

Pléiades 1B will be launched November 30th

Tuesday, November 27th, 2012

Remote sensing aficionados will be pleased to know that Astrium Services is launching their Pléiades 1B on Friday, 30 November 2012 at 11:02 pm Kourou local time (Saturday, 1 December 2:02 UTC). Pleiades 1B is the second satellite in the Pléiades constellation and will be orbited by a Soyuz launcher from Europe’s spaceport in French Guiana. Arianespace at www.arianespace.tv will be the official broadcasters of the launch.

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:

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.

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.

ASPRS Board votes unanimously for immediate funding to continue national moderate resolution imaging program

Monday, February 13th, 2012

Recently the American Society for Photogrammetry and Remote Sensing (ASPRS) Board of Directors voted unanimously for  a third resolution calling for immediate support and funding for the continuation of the Nation’s moderate resolution imaging program. Several events have led to the possible discontinuation of the collection of moderate resolution, multispectral remote sensing. One of those events was the  technical failure in the Enhanced Thematic Mapper Plus (ETM+) instrument on-board the Landsat 7 spacecraft in May 2003, and most recently the decline of the Landsat 5 spacecraft.

Although many other remote sensing efforts exist these days, the more than 40 years of uninterrupted Landsat imagery has been instrumental in monitoring ongoing stresses on the Earth from climate change, population, land use and other factors that challenge the natural resources available to mankind. According to the announcement, measuring the Earth’s resources such as food, water, and energy is best done by collecting and implementing moderate resolution imagery.

Satellite imagery in Colorado may face steep federal budget cuts

Wednesday, February 8th, 2012

The Denver area has become a center of satellite imagery providers in recent years. Proposed steep cuts in the U.S. Department of Defense budget could affect satellite-imagery providers DigitalGlobe, headquartered in Longmont, and GeoEye,based in Virginia with a processing and operations center in Thornton. Combined, the companies have about 1,200 employees.

 

This satellite image made available Sept. 26, 2009, by DigitalGlobe shows the suspected Iranian nuclear facility of Fordo near the holy Shiite city of Qom, where Iran is has begun enriching uranium, according to the U.N. atomic watchdog group, the International Atomic Energy Agency.
