pole of inaccessibility, Croatia

Sažetak
A pole of inaccessibility is a location that is most challenging to reach. In geography, it is usually the most distant location from the coastline, either on the sea or on the land. Poles of inaccessibility were usually determined for oceans and continents, but they can also be established for smaller regions, like islands or administrative regions (e.g. Croatia). Numerous administrative units want and already have determined centre, usually called a geographic centre which is determined as geometric centre (centroid) or centre of gravity. Geographic centre of Croatia falls into Bosnia and Herzegovina, due to its elongated and bent shape. Pole of inaccessibility always falls inside the region and makes it an alternative to centroid, not only to define the centre of the region but also to be used in GIS as the point that represents the polygon. In this paper, using existing methods, we determined and compared poles of inaccessibility in Croatia. Some methods give solution in plane and some on Earth’s sphere. Since Croatia is relatively small region, the Earth’s curvature does not have a substantial influence. Obviously, the solution depends on the definition of the region and since Croatia has well-indented coastline, we can consider both the mainland only or the whole country including islands and the sea. In Croatia’s mainland, the most distant point, with the distance of 61.5 km from administrative border, falls in village Mostari, located 10 km north-east of Ivanić Grad. For state administrative border (including islands and the sea), the most distant point with the distance of 73 km is located in the sea 6 km south-east of village Lopar on the island Rab.
