Ein Namensdienst für die Küste

Abstract

A Maps is the tool for orientation in unknown areas, for the orientation on maps text labels are needed. For the orientation on digital spatial data in coastal areas, a name service will be built up based on the German Coastal Gazetteer. A gazetteer is a multidimensional link-list of geographic names, geographic objects and their positions. The Coastal Gazetteer considers additional the contemporaneity. This data is stored in a PostGIS-database. For the name service it is filtered for a time validity. The results are transformed by Geoserver to an OGC-conform WMS. To design the labels YSLD (Styled Layer Descriptor described with YAML) is used. The properties of the geo-objects influence the presentation. The properties of the geo-objects are crucial for label styling. For the scale dependent display of the labels and the font size a priority of the object types is introduced.
