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.”

In a webcast presented by Carahsoft, Intermap representatives talked about the fact that they have “the world’s largest 3D terrain database with the one meter LE 90 accuracy and consistency.” LE 90 is a linear air of 90 percent, and is commonly used for quoting and validating DEMs. LE 90 value represents the linear vertical distance of 90 percent of control points, and the respective twin matching counterparts acquired in an independent geodetic survey should be found from each other. For the U.S., which most on this call is interested in, Intermap has mapped the entire lower 48 plus some of Alaska.

The Open Geospatial Consortium (OGC) calls for participation in a major interoperability testbed, OWS-9. OWS-9 builds on the outcomes of prior OGC initiatives.
Responses are due by 5 pm EST on April 6, 2012.
A bidders’ teleconference will be held on March 9, 2012. More information at the URL below.
The Point of Contact is Nadine Alameh: techdesk@opengeospatial.org.
The OWS-9 sponsors are:
- AGC (Army Geospatial Center, US Army Corps of Engineers)
- CREAF-GeoViQua-EC (CREAF is the European Center for Research in Ecology and Forestry Applications)
- EUROCONTROL
- FAA (US Federal Aviation Administration)
- GeoConnections – Natural Resources Canada
- Lockheed Martin Corporation
- NASA (US National Aeronautics and Space Administration)
- NGA (US National Geospatial-Intelligence Agency)
- USGS (US Geological Survey)

According to a press release issued by NASA and the U.S. Geological Survey (USGS) November 18, the Landsat 5 Mission may no longer remain in operation. The reason for this is the USGS has stopped acquiring images from the 27-year-old Landsat 5 Earth observation satellite due to a rapidly degrading electronic component.

When Landsat 5 was launched in 1984 it was designed to last 3 years. The USGS assumed operation of Landsat 5 in 2001 and managed to rescue the aging satellite back from the brink of total failure on several occasions following the malfunction of key subsystems.
“This anticipated decline of Landsat 5 provides confirmation of the importance of the timely launch of the next Landsat mission and the need for an operational and reliable National Land Imaging System,” stated Anne Castle, Assistant Secretary for Water and Science at the U.S. Department of the Interior. “The USGS is committed to maintaining the unique long term imaging database that the Landsat program provides.”
The amplifier that is in jeopardy is essential for transmitting land-surface images from the Landsat 5 satellite to ground receiving stations in the U.S. and around the world. In the past 10 days, amplifier problems have significantly diminished the satellite’s ability to down load images.
Now USGS engineers have suspended imaging activities for 90 days so that they can explore possible options for restoring satellite-to-ground image transmissions.
The USGS-operated Landsat 7 is actively in orbit collecting global imagery. Launched in 1999 with a 5-year design life, Landsat 7 has experienced an instrument anomaly which reduces the amount of data collected per image. A new satellite, Landsat 8, currently named the Landsat Data Continuity Mission, is now scheduled to be launched in January 2013.
