More details on orthophoto compression are in Paul Ramsey's blog post here: įor compressing DEMs, we recommend the 'deflate' algorithm. You don't want to use JPEG compression on DEMs. The JPEG compression greatly reduces file sizes, but you only want to use it on orthoimagery. Gdal_translate -of GTIFF -co 'COMPRESS=JPEG' -co 'PHOTOMETRIC=YCBCR' -co 'TILED=YES' -co 'blockxsize=512' -co 'blockysize=2512' input.tif output.tif

This can be done with LAStools, PDAL, and other point cloud processing software packages.įor orthoimagery, using JPEG compression REALLY helps, so we recommend the following GDAL command: Point cloud data should be compressed into LAZ format to reduce file sizes. Please make sure that the coordinate system info is included in the file header. gridding of point clouds, 3D point visualization, etc.). Only data in a projected coordinate system will be available for downstream processing (i.e. We strongly recommend that all datasets be in a projected coordinate system. We have a proven platform that makes lidar data much easier to use, and increases the return on investment for any lidar data collection. If there is a dataset that you would like to have available in OpenTopography, we encourage users to contact the owners of the datasets, and ask them to contact us with regards to a potential collaboration. We are always willing to work with new partners to host datasets. Basically, we do not have unlimited funding, and the hosting of local, state, and international lidar collections is not within the purview of our NSF funding, and would require a separate funding agreement.

We do have collaborations with non-NSF organizations, however, we receive separate funding for hosting those datasets. OpenTopography is a National Science Foundation (NSF) funded facility, and as a result, we only receive funding to host Earth Science related, research-grade, topographic datasets. Unfortunately, OpenTopography does not have the resources to host all available lidar collections, and so we must prioritize which datasets we host.

NOTE: The command line command will work in UNIX, LINUX, and the Windows DOS command prompt.Īt OpenTopography we strive to make data access to quality topographic datasets as painless as possible. -f Indicates file input (as opposed to STDIN).-z Indicates that tar file is compressed with gzip.

For MAC OS, users can right-click on the file in Finder and select, 'Open with Archive Utility.app'.įor command line users: Type the following command in the directory where the '.tar.gz' files reside: tar -zxvf (replace '' with the file you wish to uncompress). For Windows OS some common programs are: 7-Zip, winzip, winrar, and IZArc. There are several programs you can use to unzip lidar data. tar.gz file to access the actual DEM files which can be imported into a GIS.

To work with a custom DEM product produced in OpenTopography, you first need to uncompress the. tar file compressed with gzip compression. Files downloaded from OpenTopography will look something like this:, where the. tar.gz files to make the files smaller and therefore convenient to download. OpenTopography writes out custom DEM data and point cloud files as. A '.tar.gz' file is a compressed archive file format similar to the more familiar. OpenTopography distributes some data as 'tarballs,' which is a specific compressed file format with the extension '.tar.gz'. Department of Agriculture National Agriculture Imagery Program (NAIP). High-resolution aerial imagery is available via the U.S. However, they are not available through OpenTopography because they were not acquired with a true photogrammetric camera and thus require additional processing. The B4 dataset had orthophotos collected concurrently with the lidar survey.
