How does one distinguish between tropical rainforests and tropical grasslands on satellites images ?

Answer

Tropical rainforests have a near continuous canopy with few clearings. Tall trees 75 to 80 metres can be easily recognised under stereoscope by their dome like tops. They appear as unbroken sheet of dark tone on the photograph. Tropical grassland (Savanna) is marked by scattered groves. Grass appears in light grey tones and trees in darker tones.
