- Hyperspectral lidar?? Read all about it in this new paper in Optical Engineering, linked from the QFo Facebook page (link at left), by Eetu Puttonen and the remote sensing group at the Finnish Geodetic Institute.
- An article by TLSIIGers Kim Calders and colleagues, entitled Nondestructive Estimates of Above-Ground Biomass using Terrestrial Laser Scanning, in Methods in Ecology and Evolution, shows how Quantitative Structure Modeling (QSM) from Riegl VZ-400 scans can measure biomass in Australian Eucalyptus stands more accurately than allometric equations. Validation is by destructive sampling.
- Kim Calders at Wageningen also reports a new article in Atmospheric Environment on a novel use of TLS — relating 3-D structure to particulate matter deposition. And watch this fly-through of a main street scanned with the Riegl VZ-400 for the paper.
- A new paper in Agricultural and Forest Meteorology describes the development and characteristics of the Salford Advanced Laser Canopy Analyzer (SALCA). Congrats to Mark Danson and co-authors!
- Lucy Walker has added her talk on 4-D scanning with the SALCA to the ForestSat presentation page. View spring green-up images and plant area profiles from two sites and three time periods to watch the leaves grow.
ALS–TLS–Hyperspectral Merging at Suburban Luton, UK
- Visit this blog to view urban habitat mapping from ALS, TLS, and hyperspectral imaging by TLSIIG members Steve Hancock and Mat Disney. Your garden may be next!
Zebedee Scanner from CSIRO
- No more tripods, leveling, and dancing around scanners! CSIRO’s new handheld Zebedee generates point clouds as you walk through the woods. Just “shake and bake”! Watch the video to see how it works.
VegNet Autonomous Scanner
- Tired of lugging your scanner into the woods to follow tree growth and LAI changes? Check out the VegNet lidar instrument, which is permanently mounted in the forest and does an autonomous daily azimuth scan at a constant zenith angle of 57.5°. Read about it in a paper in the journal Sensors by TLSIIG members Darius Culvenor, Glenn Newnham, et al.
