  • ESA CORINE Land Cover

NASA LAND COVER TYPE MCD12Q1 (VERSION 6)

Period: 2001 – 2017 Sensor: MODIS Terra + Aqua Frequency: Yearly Resolutions: 500m Extent: Global Data can be accessed here. Algorithm description: The product consists of 13 science data sets including tree layer classes based on FAO LCCS. The algorithm is based on supervised classification. Inter-annual variability is caused by classifier instability. To remove this instability ‘Hidden Markov Model’ is used to…

ESA CCI LAND COVER MAP (SECOND PHASE)

Period: 1992 – 2015 Sensor: AVHRR, PROBA-V, SPOT-VGT, MERIS FR & RR Frequency: Yearly Resolutions: 300m Extent: Global Data can be accessed here. Algorithm description: The algorithm uses time series of surface reflectance data and derives land cover map using ‘machine learning’ and unsupervised classification algorithms. FAO LCCS system is followed for classification. Accuracy:  Detailed validation is still ongoing, however, some limited work…
