Sažetak
A vast majority of Adriatic Sea islands, especially the larger ones, were represented on many early modern nautical charts and geographic maps. However, their exact number and geometric appearance, same as the number of place names related to islands (or to certain geographical features), differ among these charts and maps. The main goal of the research was to examine how cartographic generalization and map aesthetics affected the representations of Adriatic Sea islands on selected charts and maps – both in terms of ‘appearances’ and ‘disappearances’ of certain islands and in terms of geometric varieties of their appearance according to the following parameters: type of map, year of production, map scale, physical dimensions of the map, area of the island in reality, and island proximity to larger cities and important contemporary sailing routes. The complete research sample consists of Early Modern portolan charts with rhumb networks, Early Modern printed navigational charts on which graticules of longitudes and latitudes are displayed, and Early Modern geographic maps with graticules. Selected Adriatic Sea islands (both larger and smaller ones) were statistically processed to determine the variations oftheir place names and whether they were displayed on charts and maps, depending on the particular map type and its map scale. The renderings of their coastlines were converted into vector datasets, which were used to compute variations in their visual appearances, both in terms of their mapping accuracy (in comparison with the modern reference map, which was considered to be error-free), and in terms of their mapping precision (the computation of geometric similarities or dissimilarities within the complete island-dataset and within the particular map-type related data-subsets). The research outcome is expected to serve as a supplement to existing knowledge about island representations on early modern maps and charts in general and to offer methodological advances in quantitative analysis of the geographical content of old charts and maps.
