2018 AK DGGS Lidar: Turnagain Pass, AK Point Cloud files with Orthometric Vertical Datum North American Vertical Datum of 1988 (NAVD88) using GEOID12B
Below are links to the files that make up the 2018 AK DGGS Lidar: Turnagain Pass, AK dataset in an orthometric vertical datum North American Vertical Datum of 1988 (NAVD88) using GEOID12B. This HTML
file is here to emulate the access typical of 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 can be done with the free and open source 'laszip' program available at
https://rapidlasso.de/laszip/
(source at https://github.com/LASzip/LASzip). This is not the same as the more general zip format.
You may also want to try the uGet program using the list of URLs in file urllist9582.txt.
Several posts on the GeoZone blog provide help with downloading, including:
The total size to download all the files is 5.19 GB. There are 230 LAZ files and the summary class table is:
| Class Number | Class Name | Points |
|---|
| 1 | Unclassified | 143240 |
| 2 | Ground | 419576770 |
| 3 | Low Vegetation | 33206567 |
| 4 | Medium Vegetation | 149652159 |
| 5 | High Vegetation | 312364559 |
| 7 | Low Point (noise) | 21082 |
| 8 | Model Key Point | 20198 |
Georeferencing Note
You may find the georeferencing on the files refers to generic NAD83 (EPSG code 4269).
All files are in a more recent realization of NAD83 such as
NAD83(CORS96), NAD83(HARN), NAD83(NSRS2007), or NAD83(2011).
Cloud Access
This data is now in an AWS S3 bucket at s3://noaa-nos-coastal-lidar-pds/laz/geoid12b/9582.
