Outer Hebrides, off the northwestern coast of the Scotland extending in the Atlantic, is comprised in the Western Isles. The Outer Hebrides are separated from the Inner Hebrides by the Minch and Little Minch channels in the north and by the Sea of the Hebrides in the south. The Outer Hebrides lies in a crescent about 65 km from the Scottish mainland and Its geo-location is 56°46′38″N-59°8′4″N, 8°39′1″W-5°48′37″W[1-6] (Figure 1, Figure 2).

Outer Hebrides mainly consists of Lewis and Harris, North Uist, Benbecula, South Uist and Barra-Vatersay[7]. There are 2389 islands and islets with area bigger than 25 m2 in the Outer Hebrides. Lewis and Harris with area of 2,169.36 km2 and coastline of 934.16 km is the largest and most northerly of the Outer Hebrides islands, lying 39 km from the west coast of the Scottish mainland and separated from it by the Minch channel. The North Usit is joined by constructed causeways with the Baleshare island in the northeast and with the Berneray island in the south. The Benbecula is similarly connected with the Eileann Chearabhaigh island in the north and the Flodaigh island in the south. Other larger islands include Great Bernera, Grimsay-Ronay, Taransay, Scarp, Pabbay, Isle of Scalpay, Eriskay, Hirta, Mingulay, Sandray, Wiay, Vallay, Ceann Ear, Boreray, Seaforth, Pabbay, Fuday, Barra Head, Ensay, Kirkbost, Killegray, Ceann Iar, Garbh Eilean, Hellisay, Ceallasaigh Mor-Beag, Eilean Iubhard, Mealasta, Little Bernera, North Rona, Soay, Gighay, Stromay, Pabaigh Mor, et al. (Table 1). The total area of the Outer Hebrides is 3,184.51 km² and the total coastline length is 3,393.13 km.
