Estonian plant cover height model (CHM — Canopy Height Model)

The plant cover height model (CHM — Canopy Height Model) indicates the height of vegetation above the ground. The data cover the whole of Estonia (except the areas along the Russian border). The model is divided into height classes where pixels below 1 m are transparent. The following height classes are: 1 to 4 m, 4-10 m, 10-20 m, 20-30 m pixels and more than 30 m pixels. The calculation assumes that there are no trees above 50 metres in height in Estonia. Data resolution 4-10 m (pixel size 4 m (from 2017) — 10 m (up to 2016 year)). Heights in steps of 0.5 m. The first layer of plant cover height model covering Estonia is from 2008 to 2011. The second layer of plant cover height model covering Estonia is from 2012 to 2015. The third layer covering Estonia from 2017 to 2018. The fourth layer covering Estonia from 2019 to 2020.
