2011 USGS Lidar: Baldwin County, AL 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 2011 USGS Lidar: Baldwin County, AL 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 urllist1425.txt.
Several posts on the GeoZone blog provide help with downloading, including:
The total size to download all the files is 8.8G. There are 464 LAZ files and the summary class table is:
Class Number | Class Name | Points |
1 | Unclassified | 837873109 |
2 | Ground | 373339884 |
5 | High Vegetation | 17499145 |
7 | Low Point (noise) | 194601 |
9 | Water | 85776248 |
10 | Ignored Ground (near breakline) | 917183 |
12 | Overlap | 42047650 |
13 | Bridge Deck | 987218770 |
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).
Cloud Access
This data is now in an AWS S3 bucket at s3://noaa-nos-coastal-lidar-pds/laz/geoid18/1425.
