A national lidar dataset refers to a high-resolution

topographic 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
Canada	Montréal completed, 2015	10	[1]
Denmark	Completed, 2008, 2013	4	[2],[3]	Pointspacing is from 4/m2 to 1.6m
Estonia	Completed	0.15-18	[4]	Planning to cover the country after each four years
Finland	Completed	0.5	[5]
Latvia	In progress, 2013-2018	4	[6]
Netherlands	Completed, 2003	1/25 - 1/16 (AHN1), 6 - 10 (AHN2)	[7],[8], [9],[10],[11],[12].	Pointspacing is 4-5 m for AHN-1 and 6-10 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
Poland	In progress	from 4 to 12	[13]	IT project for protecting the country against extraordinary threats
Slovenia	Completed, 2015	5	[14]	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	Completed, 2015. Second survey in progress	0.5	[15]	It is part of National Orthophoto Project
Sweden	In progress	0.5	[16]
Switzerland	Completed, in progress (until 2024)	1, 5 - 15	[17]	Open Data access,Sample LIDAR Dataset - Switzerland
USA	In discussion	n/a	[18]	National LIDAR Dataset - USA
England	In progress	0.5, 1.0, 4.0 and 16.0	[19], [20]	National LIDAR Dataset - England, carried out by the Environment Agency. 75% coverage of England at 2m resolution or higher. Composite, Tiled (historic) LIDAR and Point Cloud are available as Open Data.
New Zealand	In discussion	n/a	[21]	Requests for source point cloud data by contacting LINZ directly at [email protected]
