1. The Maine Geological Survey has been using LiDAR from successive year flights to study Goochs Beach.
2. By comparing the digital elevation models for the sand dunes, movement and accretion/erosion can be determined.
3. The surveys represent a snapshot in time of an ongoing process, but they are yielding important insight.
Howard Butler continues to do some very important data format work focused around his libLAS libraries.
On a somewhat related note the ASTM E57.04 Data Interoperability standard was balloted today.
The second laser scanning webinar in the Autodesk, Topcon, Spar series will be one week from today – March 25, 2010 from 10:00 to 11:00 AM PST.
1. A second important article in this month’s PE & RS concerns mobile mapping systems.
2. The ASPRS will host the first meeting of the Mobile Mapping System committee in April.
3. Many thanks to all for your comments and support as this marks my 300th post.
This presentation on breaklines by Kenny Legleiter at Merrick provides an excellent introduction to the issues surrounding the use of breaklines.
1. Medical researchers at UCI’s Beckman Laser Scanning Institute have developed optical, metabolic signatures for malignant breast cancer tumors.
2. Traditional mammography often misses tumors in dense tissue.
3. Young women with tumors are often mis-diagnosed.
For those interested in some of the current thinking on LiDAR data compression Michael Rosen from LizardTech has posted an excellent summary of the recent ILMF presentations.
For those who were not able to attend the live session please visit the Autodesk Civil Engineering Resource Center.
Brent Gelhar from Optech correctly pointed out to me that my comment about structured light laser scanners being like a flash LiDAR was well, let’s say, wrong.
The National Science Foundation is funding a two-day workshop June 1-2 at the University Corporation for Atmospheric Research (UCAR) in Boulder, Colorado.
