2012 PSLC Lidar: Quinault (Delivery 2) Point Cloud files with Orthometric Vertical Datum North American Vertical Datum of 1988 (NAVD88) using GEOID18

Below are links to the files that make up the 2012 PSLC Lidar: Quinault (Delivery 2) dataset in an orthometric vertical datum North American Vertical Datum of 1988 (NAVD88) using GEOID18. This HTML file is here to emulate the access you would have gotten through an ftp site. The files containing geospatial indices, metadata, etc., are listed first, followed by the files. To download in bulk, it is suggested you use a program such as wget (example below). The geospatial index file in shapefile format also has a URL attribute that some GIS programs can use to download files. You can also subset the data, make derived products, and change projection, datum, etc., using the Digital Coast Data Access Viewer (add to cart, the link to bulk download or LAZ fmt will take you here).

The files are in LAZ format, a lossless compressed version of the ASPRS LAS format. The compression and decompression is done with the free and open source 'laszip' program available at https://laszip.org. This is not the same as the more general zip format. Many geospatial programs will read LAZ files natively and decompression is often not necessary. There is a list of software with native support on the laszip site.

There are many download managers you can use to get all the data. An example is the uGet program using the list of URLs in file urllist2508.txt. Several posts on the GeoZone blog provide help with downloading, including:

• Using uGet to download bulk lidar
• Downloading a subset of files based on a polygon
• Downloading on Windows without additional programs

The total size to download all the files is 23G. There are 404 LAZ files and the summary class table is:

Class Number	Class Name	Points
1	Unclassified	4687404719
2	Ground	523911645
3	Low Vegetation	3
8	Model Key Point	876

Georeferencing Note

You may find the georeferencing on the files refers to generic NAD83 (EPSG code 4269). All files, with the exception of the few in WGS84, are in a more recent realization of NAD83 such as NAD83(CORS96), NAD83(HARN), NAD83(NSRS2007), or NAD83(2011).
