Sažetak
According to the published sources, the area of the continental part of Croatia is equal to 56538 km2. However, the different numerical values can be found as well. The area of the Croatian part of the Adriatic sea has not been published. With the development of computers, the method of area determination on the basis of coordinates has become more important because it enables the area determination of the extremely irregular shapes, and the coordinates of boundary points can be obtained directly from a map by means of digitization. Our own program has been designed for the digitization with precise large digitizer CalComp 9100. The program is assigned to digitization of single points with the number of attributes, as well as to digitization of contour lines and boundary lines of territory units. The area of 90 largest Croatian islands and of 94 territory units at the continental part of Croatia has been computed. After the appropriate classification, the final values of county district areas have been achieved. In order to get a better insight in the distortion of area due to map projection, the areas are computed without the corrections and with the corrections. The absolute value of the maximum relative error of area computed with and without the correction was about 0.1 %. The total area of the continental part of the Republic of Croatia has been computed as a sum of all county district areas and makes 56488 km2. It is 50 km2 less then the most frequent quoted value. In the previous paper there is a review of obtained accuracy estimation for the area of islands and for the area of continental part of Croatia on the basis of the mean square error of points belonging to the boundary lines. The mean square error of the total area of the continental part of Croatia is about 13 km2. It is interesting, that the islands Krk and Cres are of approximately the same area, and that there are no scientific arguments for declaring Krk as the largest island in the Adriatic sea. Our results are in accordance with the recent investigations of other authors. Furthermore, besides the area of territory units in the continental part of Croatia, we have computed also the appropriate parts of the Adriatic sea. The final values for these areas have been achieved. The total area of the part of the Adriatic sea belonging to Croatia is about 31421 km2.
