I just found out that the Trammel map has a resolution of 6144 x 4096 tiles (pixels). So, if we say 1 tile corresponds to roughly 1 meter square or 10 square feet, then trammel is roughly 25 square kilometers or 10 square miles. Now, we can say that more than three quarters of this map is either water or unreachable locations, so we end up with 6-7 square kilometers or 2-3 square miles. If that is the case, Trammel is as big as Gibraltar. Adding up all maps: Trammel & Felucca: 6144 x 4096 Ilshenar: 2304 x 1600 Malas: 2560 x 2048 Tokuno: 1448 x 1448 Ter Mur: 1280 x 4096 Total are in tiles: 66,600,512 Approximate accesible tiles (1/4th): 16,650,128 If 1 tile is about 1 square meter, whole map corresponds to roughly 17 square kilometers or 6.5 square miles. For comparison, Manhattan is 59 square kilometers or 23 square miles and central park is 3.41 square kilometers or 1.32 square miles.
