PE&RS article out: Generating Pit-Free Canopy Height Models

[Martin Isenburg]

Hello,

the full journal article on how to generate pit-free Canopy Height
Models (CHMs) that is a joint work between researchers of ITC Enschede
/ UTwente and rapidlasso has finally gone to print in the September
edition of the ASPRS PE&RS journal. See attached pic or this link for
the abstract:

http://www.asprs.org/a/publications/pers/2014journals/PE&RS_Sept_2014_Flipping/HTML/index.html#863

you can find this algorithm implemented

(1) as a batch script in the example_batch_script folder of LAStools
(2) in the QGIS processing toolbox "LAStools Pipelines"
(3) in the ArcGIS toolbox "LAStools Pipelines"

the correct citation is

Khosravipour, A., Skidmore, A.K., Isenburg, M., Wang, T.J., Hussin,
Y.A., 2014. Generating pit - free canopy height models from airborne
lidar. PE&RS = Photogrammetric Engineering and Remote Sensing 80,
863-872.

you can find a shorter 4-page extended abstract that was accompanying
the Silvilaser 2013 poster here

Congrats to Anahita for putting this all together. And also kudos for
all the hard work. These 10 innocent pages do not show the many
laborious hours that went into the manual comparison of the tree
detection results to the data collected in the field, which was needed
to rigorously quantify the omission and comission errors for the
standard, the smoothed, and the pit-free CHMs ... (-:
