Speakers notes

Part of a presenation given at NACIS 2013: https://github.com/springmeyer/cloudless-nacis2013

• Bahamas - land really pops due to blurred shallow nearshore
• Australia - rich hues
• Great Barrier Reef - Extremely subtle textures visible + water mask helps show smallest reefs
• Amur River - effectively shows many combined flood events / murky water in delta
• Taiwan - deforestation clearly visible
• Tibet - Jewel lakes
