- •
Current high-resolution global forest-cover maps target green or wet season images.
- •
In the tropics, low vegetation is easily confused with forest in the wet season.
- •
Good separability between forest and low vegetation occurs in the dry season.
- •
Combining wet and dry images can overestimate forests and subsequent deforestation.
- •
A Wetness Index is proposed to guide image selection to minimize class confusion.
