MOD12 is a MODIS product at 240m resolution. Landsat produces 30m resolution products, which I resampled to 240m resulting in a raster of proportion forest cover in each 240m pixel (based on the mean of the 8x30m cells it covers). The MOD12 raster has been reclassed to binary forest/non-forest.

My question is: what proportion of the 240m area sensed by MODIS must be forest before it is defined as forest? Is it majority (50%+) or something more complex? My reason for wanting to know this is to reclass the Landsat proportional raster to a binary raster that mirrors the MOD12 data.

All of the detailed information about MOD12 data can be found in the Algorithm Theoretical Basis Document (ATBD). On page 23, it says that the forest classes require >60% coverage of the pixel.
