Creating a Cartographic Visualization of all Croatian Islands on a Poster Using Monochrome Mapping

Croatia is internationally known as the country with thousand islands. The exact number of naturally formed parts of the land surrounded by the sea with an area of more than 1 km2 is defined by the law and amounts exactly 78. It is not an easy task to show all the islands on one map, while at the same time their indentation, shape, relief and size are visible and highlighted. Thinking about the kind of cartographic display that would emphasize the appearance, shape, relief and size of each individual island as a separate entity, we decided to create a poster in A1 paper format on which we placed all the islands according to their surface area. The marine benthos layer was used as a source of spatial data for creating the island polygon by connecting to the Web Feature Service (WFS) of the environmental protection information system called 'bioportal'. It is a layer that contains the entire territorial sea of the Republic of Croatia, and which was used to create the polygons of the island from its internal voids. The shaded relief and contour lines of all islands were obtained by processing the European digital surface model (EU-DEM). The entire processing of the spatial and attribute data of the polygon, as well as the final creation of the map design, was performed in QGIS. In the final representation of all Croatian islands, a shade of blue was used for the background of the map to give the impression of a marine environment. In addition, different shades of blue were used to display the polygons of the island, as well as the shaded relief, layers, and the entire text in the map description. Therefore, it can be said that we created the first unique representation of the Croatian islands using monochrome mapping of cartographic content.
