|Image features used for level 1 and level 2 classifications|
|Level 1 classification||Open water||Object mean band 4 (near infrared): threshold of 5.5%||April||Light in band 4 absorbed by water|
|Built up & bare ground; wet vegetation types; dry vegetation types||Object mean band 3 (red)||April||Vegetation type discrimination|
|Object mean band 2 (green)||November||Identification of healthy vegetation|
|Object mean band 3||November||Vegetation type discrimination|
|Object mean band 5 (mid infrared)||November||Vegetation and soil moisture content|
|Object mean band 7 (mid infrared)||November||Identification of built up areas and bare ground|
|NDVI difference, January to November||Differentiation of vegetation types|
|Level 2 classification||Woodland & dense savannah*; crops & open savannah*||Object mean band 2||April||Related to healthy vegetation, biomass, plant type or vegetation moisture content|
|Object mean band 3||April|
|Object mean band 4||April|
|Object mean band 5||April|
|NDVI difference, January to April, January to November and April to November||Differentiation of vegetation types|
|Seasonally flooding grassland**; lake fringe swamps**||Object mean band 4||November||Identification of vegetation and soil moisture content, biomass, plant vigour and water|
|Object mean band 5||November|
*Obtained using sub-classifications of the “dry vegetation types” class.
