AusCover Lidar data : Free LIDAR imagery

[Olsen, Richard (RC) (CIV)]

Noted that these are Riegl data - are waveforms included?

Bulent,

As you might have guessed, the AusCover Lidar data sets are from us. If you are interested in them, we obviously also have them as individual laz-files. We also have a lot of other lidar data that can be made available, but all of it is from Australia (and one small set from the European Alps). We have never flown in Turkey, although that would surely be interesting.

Regards,
Jorg.

Bulent,

go to http://laszip.org and scroll to the end of the page. You will see a list of most open LiDAR download resources in LAZ or LAS format that I am aware of. Altogether the linked data sets probably total somewhere between 10 - 50 TB of LiDAR files ...

One site that is not yet linked the http://laszip.org site yet is the AusCover LiDAR dats that is pretty wonderful (collected by Airborne Research Australia's Eco-Dimona gliders equipped with RIEGL full waveform scanners). Unfortunately the LAZ files are not provided one by one but are winzipped together into gigantic ZIP files that are 4 to 6 GB in size. That is supposed to get fixed soon so you can get "preview" access to the data with curl before deciding to download it:

curl -s http://www.cs.unc.edu/~isenburg/lastools/las14/las14_type0_fredericton_LAStools.laz | lasinfo -stdin

curl -s http://www.cs.unc.edu/~isenburg/lastools/las14/las14_type0_fredericton_LAStools.laz | lasview -stdin

However, if you can handle 4 to 6 GB downloads of incredibly dense Australian ecological "super sites" data then go to the site below. You will find discrete return LAZ files as well as full waveform LiDAR in the GeoLas format (that can be on-the-fly converted to the PulseWaves format when read with either of pulseview.exe, pulseinfo.exe, or pulse2pulse.exe of http://pulsewaves.org):

Dear Bulent,

We have a lot of lidar data sets that freely available. If you tell me what you want to do with it - and where you are, I can see if we have something useful.

Jorg.

Hello Richard,

as Jorg pointed out, the full waveform data is indeed available and I
recently made a post about this in the PulseWaves group with a link to
the data and descriptions how to download and process it with the
PULSEtools prototypes ...

http://groups.google.com/group/pulsewaves/browse_thread/thread/753b71e5d4748f4b

In fact I am waiting for Jorg to follow up my message in the
PulseWaves group with a few more details on how this data was
captured, processed, and exported for distribution. I am enroute to
Jorg's lab in Adelaide so I will make him send those details soon.

Martin

PS: I "smuggled" some German Ritter Sport chocolate bars past the
quarantine officer and his canine friend at Perth airport for you. Not
sending those full waveform details may result in a sudden
uncontrollable craving for sweets ... (-;
