Current geoportals and metadata catalogues, as user interfaces for discovery and exploration for geodata do still suffer from lacking usability, regardless whether experts or non-expert users are considered. Design patterns are well established in software development to tackle frequently occurring problems. Usability patterns are a specialization of such design patterns to specifically address user interface issues and related software solutions. However, existing usability patterns are not sufficient to cope with GI-usability issues as for instance related to discovery of geodata. This poster submission introduces an adapted GI-usability pattern concept.
