Elevation Data
All of the Estonian territory is covered by LIDAR collected elevation data of excellent quality.
For the first two rounds, scanning was done by Leica ALS50-II scanner. Flying took place at altitude 2400m and at 1300m in rural areas. The third round started in 2017 with Riegl VQ-1560i scanner.

Raw LiDAR material is in LAZ format and digital elevation models (grid sizes 1m, 5m, 10m, 25m) are in GeoTIFF or XYZ ASCII format. DEMs include DTM, nDSM and CHM models. Latest DEMs are made from 2012-2018 springtime LiDAR flight data (including low altitude flights above major cities).
There are also elevation lines (2.5m interval) and related elevation points bundled into Estonian Basic Map vector dataset.
All the elevation data is in EH2000 height system (EVRS - European Vertical Reference System), based on NAP (Normaal Amsterdams Peil).
Each LAZ file covers 1 km2 and the classification has been made automatically. Possible class values are:
1 - Unclassified
2 - Terrain (including flagged keypoints)
5 - First and middle reflections (mostly trees/ bushes)
6 - Buildings (points which fall inside the buildings layer of Estonian Topographic Database, starting from the year 2012 data )
7 - Noise (below terrain)
9 - Water (points which fall inside the water layer of Estonian Topographic Database, starting from the year 2012 data)
17 - Terrain under bridges (overlap bit)
18 - Noise (above terrain)
