2007 USACE NCMP Topobathy Lidar: Lake Superior (WI) & Lake Ontario (NY) Point Cloud files with Orthometric Vertical Datum NAVD88 using GEOID12A

Below are links to the files that make up the 2007 USACE NCMP Topobathy Lidar: Lake Superior (WI) & Lake Ontario (NY) dataset in an orthometric vertical datum NAVD88 using GEOID12A. 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 http://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.

Example to download entire data set using wget (windows version at http://gnuwin32.sourceforge.net/packages/wget.htm):
wget -np -r -nH -L --cut-dirs=2 https://coast.noaa.gov/htdata/lidar1_z/geoid12a/data/114/
This will give you the directory structure starting with geoid12a. Modify the --cut-dirs=2 argument to modify the start directory (e.g. --cut-dirs=4 will start at 114). Wget is a command-line program and the output will be to the directory you run it in. More options and information can be found at http://www.gnu.org/software/wget/manual/wget.html. The other options in the example mean:


If you have problems with wget that look like an authorization or certificate issue, you may need to add the option "--no-check-certificate".

The total size to download all the files is 1.7G.

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).
