SLICER Data Browser
(Scanning Lidar Imager of Canopies by Echo Recovery)
Data Browser and Editor (V. 2.0)
An updated SLICER data browser and editor (V. 2.0) is available.
This browser is a set
of IDL procedures (*.pro) for use with .dat SLICER data files. A sample.dat file
from the BOREAS Northern Study Area (Old Jack Pine flux tower) in Canada is
included in the ftp directory.
Binary File -- use "save link as" to download

The browser has been updated to function
properly under Windows on a PC and includes some display augmentations.
See the READMEv2.TXT file in the browser directory for information on using the
The .TXT and .pro files are ascii files. Sample.dat is a binary file.
For SLICER users who have previously only worked with .geo files, the .dat
structure is a more user friendly data structure developed for the BOREAS
project. It includes an automated identification of the beginning, peak,
and end of the ground return, and coverts roll, pitch, and yaw to a laser
vector represented by azimuth and inclination. In addition to the BOREAS
acquisitions, some additional SLICER data sets have been converted from
.geo to .dat files.
To date these include Duke Forest, Mahantango, and the Wind River Canopy
Crane. A description of the .dat data structure and derivation of the .dat
parameters is contained in documentation included in the ftp directory.
The documentation is saved as a postscript file (STRUCTURE.ps) and a Microsoft Word Rich Text
Format file (STRUCTURE.rtf)
