Is there any freely available pointcloud data? I'm especially interested in dense clouds of small areas(5m to 100m radius) but anything else would be fine too.

Edit: I've found that these pages have very nice and easy to access point cloud data. Thanks for all the answers!

There are either too many possible answers, or good answers would be too long for this format. Please add details to narrow the answer set or to isolate an issue that can be answered in a few paragraphs.If this question can be reworded to fit the rules in the help center, please edit the question.

Please clarify "point clouds". Not everybody will be familiar with this terminology. You also do not specify exactly what you are after. Do you want any format, ASCII, LAS, etc? Do you want discrete return lidar, waveform lidar or any source? What features are you after, buildings, vegetation? – Jeffrey Evans Feb 10 at 18:38

West Virginia View has some first/last files here: http://www.wvview.org/data/lidar/Gilmer/las/

This takes you through a USGS viewer, which links out to other sites (which may not have the design/interface):

For our book "Open Source GIS: A GRASS GIS Approach" we have published a large North Carolina dataset. It contains the raw Lidar data as separated files which you can grab at http://www.grassbook.org/ncexternal/ (Lidar multi-return data).

You can find many direct links to LAS / LAZ LiDAR data here LASzip.org

We're looking for long answers that provide some explanation and context. Don't just give a one-line answer; explain why your answer is right, ideally with citations. Answers that don't include explanations may be removed.

We appreciate replies from vendors and other commercially interested parties, Martin, but in such cases to retain credibility it's crucial that you identify your connection with the solution you are recommending. – whuber Feb 13 '12 at 15:45

@whuber, the site lists datasets that are available. It's not Martin's tools despite the name. – jwx Feb 10 at 18:30

Ohio has LAS State wide datasets located here. The web page has a map extract select tool to download various extents/sets of data.

Generate your own with a Kinect. It will provide a pointcloud with cm-scale precision for areas up to 5 m^2, and has a maximum range and FOV of about 15 m, although it is not very precise at that range. Just collect your data in the morning/evening when the sun is low, or at night.

Do you have a good tutorial in mind that shows how to carry this project out? – jwx Feb 15 at 18:14

Autodesk's 123D Create application can generate point clouds from photos.

Just take photos of something from a few angles and then hit 'go'. I am not affiliated at all. I like it a lot, though. Very nice software.

Very nice app. I also tried VisualSFM which may not produce nice polygon meshes but offers a lot more control. – Markus May 1 '14 at 7:57

http://liblas.org/samples/ has a extensive sample library of somewhat interesting data, though its primary purpose is for providing examples of variability in LAS data.

MD DNR has some sample LIDAR datasets available on this page, although it's already been separated out into first- and last-returns.

Well I have written tutorial about all the free sources of LIDAR data. You can mostly find free data from usa. But my article have data from Europe, south america and few countries from Africa. But did not find any data from ASIA. For my article go to http://grindgis.com/data/free-lidar-data-download. And for the USA you can directly go to WIKIPEDIA website and choose the desire state. https://en.wikipedia.org/wiki/National_Lidar_Dataset_(United_States)

For Slovenia free raw (zlas) files. You have to download each sheet manually. Data cloud is 1mx1m and one sheet is 1km2. OTR file has already classified point cloud for ground.

Why did you all go with ZLAS and not LAZ? – jwx Feb 10 at 18:30
    
I really dont know since it is national project in hands of state environment agency. Most probably because smaller files to download. It is easy to decompress them with this tool arcgis.com/home/item.html?id=787794cdbd384261bc9bf99a860a374f I know that with free access to data we should have open format lidar data, but it is what it is. – Jost Hobic Feb 11 at 8:26
    
you get a higher compression ratio with ZLAS opposed to LAZ? Also, the tools for LAZ are free and public....Just saying. – jwx Feb 15 at 18:13
