2015 FEMA Lidar: Region 2 NY Great Lakes Area 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 2015 FEMA Lidar: Region 2 NY Great Lakes Area dataset in an orthometric vertical datum North American Vertical Datum of 1988 (NAVD88) using GEOID18. 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 urllist8764.txt. Several posts on the GeoZone blog provide help with downloading, including:

The total size to download all the files is 356G. There are 3069 LAZ files and the summary class table is:

This dataset has 705 points in additional unexpected classes that may be misclassified.

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).
