Abstract

The proposal of a new display of depth contours and sector lights symbols on paper navigational charts published by the Hydrographic Institute of the Republic of Croatia (HHI) in Split is presented in this paper. Since the symbols on the HHI paper charts are defined in the publication entitled “Symbols and Abbreviations Used on Charts”, which is produced by each Member State for its charts by the recommendations of the International Hydrographic Organization (IHO), the proposed displays are in accordance with the specified publication. By studying all versions of the mentioned publication, the historical development of depth contours and sector lights display is presented. By comparing clips from the official paper chars scale of 1:100 000 with a classic display of these symbols and clips from the created samples of paper charts with the proposed display of these symbols, the impact on the readability of other symbols is analyzed and improvements of depth contours and sector lights display are shown.
