Utjecaj mjerila karte na određivanje duljine obalne crte i površine otoka u Jadranskom moru - primjer otoka Raba

Opisan je postupak određivanja duljine obalne crte i površine otoka Raba s karata mjerila 1:25 000, 1:50 000, 1:100 000, 1:200 000, 1:300 000, 1:500 000, 1:1 000 000 i 1:2 000 000. Listovi karata u mjerilu 1:25 000, 1:100 000 i 1:200 000 dobiveni su u georeferenciranom rasterskom formatu, a ostali su skenirani i georeferencirani. Izvršena je potom ručna vektorizacija obalne crte i transformacija svih koordinata u 5. zonu Gauss-Krügerove projekcije. Duljina obalne crte i površina otoka izračunana je u Gauss-Krügerovoj projekciji pri čem su uzete u obzir deformacije projekcije. Rezultati su dani u tablicama i prikazani grafički.

The Effect of Map Scale on the Determination of the Coastline Length and the Area of Islands in the Adriatic Sea - the Example of the Island of Rab

The procedure to determine the length of the coastline and the area of the island of Rab from maps of scales 1:25,000, 1:50,000, 1:100,000, 1:200,000, 1:300,000, 1:500,000, 1:1,000,000 and 1:2 000 000. is described. The map sheets in the scale 1:25 000, 1:100 000 and 1:200 000 were obtained in georeferenced raster format, and the others were scanned and georeferenced. Manual vectorization of the coastline and transformation of all coordinates into the 5th zone of the Gauss-Krüger projection was then performed. The length of the coastline and the area of the island was calculated in the Gauss-Krüger projection, taking into account the deformations of the projection. The results are given in tables and presented graphically.
