change-confidence

This layer is only provided for years after the BaseYear 2015. * 0 - No change. No change in discrete class between year and previous year detected. * 1 - Potential change. BFASTmon detected break in second half of NRT year - potential change. * 2 - Medium confidence. Imprint of urban, permanent water, snow or wetland OR change detected by BFAST but HMM model didn’t confirm this break in higher resolution OR change detected by BFASTmon in the first half of NRT year. * 3 - High confidence. BFAST detected a change and HMM confirmed this change in higher resolution.

#FFBB22

Shrubs. Woody perennial plants with persistent and woody stems and without any defined main stem being less than 5 m tall. The shrub foliage can be either evergreen or deciduous.

30

#FFFF4C

Herbaceous vegetation. Plants without persistent stem or shoots above ground and lacking definite firm structure. Tree and shrub cover is less than 10 %.

40

#F096FF

Cultivated and managed vegetation / agriculture. Lands covered with temporary crops followed by harvest and a bare soil period (e.g., single and multiple cropping systems). Note that perennial woody crops will be classified as the appropriate forest or shrub land cover type.

50

#FA0000

Urban / built up. Land covered by buildings and other man-made structures.

60

#B4B4B4

Bare / sparse vegetation. Lands with exposed soil, sand, or rocks and never has more than 10 % vegetated cover during any time of the year.

70

#F0F0F0

Snow and ice. Lands under snow or ice cover throughout the year.

80

#0032C8

Permanent water bodies. Lakes, reservoirs, and rivers. Can be either fresh or salt-water bodies.

90

#0096A0

Herbaceous wetland. Lands with a permanent mixture of water and herbaceous or woody vegetation. The vegetation can be present in either salt, brackish, or fresh water.

100

#FAE6A0

Moss and lichen.
