National lidar dataset

A national lidar dataset refers to a high-resolution lidar dataset comprising most—and ideally all—of a nation’s terrain. Datasets of this type typically meet specified quality standards and are publicly available for free (or at nominal cost) in one or more uniform formats from government or academic sources. National LiDAR datasets are used primarily in LIDAR Contour Mapping, and also for forestry, urban and rural planning, recreational, environmental, engineering, and geological studies and planning, among others.

Countries with national lidar datasets either completed or in progress include:

Country	Dataset Status	Resolution (pts/m2)	Source	Additional Information
Netherlands	Completed, 2003	1/25 - 1/16	[1],[2], [3],[4],[5],[6].	Pointspacing is 4-5 m for AHN-1 and 9 points/m2 for AHN-2. Data became available 2014. AHN-3 (third scan of the country, to be completed 2019) is partially available since September 2015
Denmark	Completed, 2008, 2013	4	[7],[8]	Pointspacing is from 4/m2 to 1.6m
Finland	Completed	0.5	[9]
Poland	In progress	from 4 to 12	[10]	IT project for protecting the country against extraordinary threats
Slovenia	Completed, 2015	5	[11]	Created by the Slovenian Environment Agency as a basis for environmental threat protection models. Some landslide- and flood-prone areas were scanned at 10 pts/m2, some remote areas only at 2 pts/m2. Data is available for free for any purpose (attribution is required).
Spain	In progress	0.5	[12]	It is part of national orthophoto project
Sweden	In progress	0.5	[13]
Switzerland	Completed	1	[14]
USA	In discussion	n/a	[15]	National LIDAR Dataset - USA
England	In progress	0.5, 1.0, 4.0 and 16.0	[16]	National LIDAR Dataset - England, carried out by the Environment Agency. 72% coverage of England at 2m resolution. Composite and Tiled (historic) LIDAR are available as Open Data.
