    1. Imagine an island (e.g: Bermuda, Hook Island, Sardinia, etc)

    2. Draw a square or rectangle approximating all of the land not currently touching water (e.g: All pixels must not contain water)

    3. Draw a larger red square encompassing the smaller red square or rectangle.

    4. Subtract any brown, green, or “land” pixels, and add them to the total count of Box_1.

    5. Remove green, blue and other “water” pixels from Box_2.

    6. Your final result will be a red outline precisely mapping the coastline of the island in question. You can now measure distance by taking pixels and multiplying by the scale of the zoom-distance (parralax).
