This paper describes the design and implementation issues of the STepLib geolibrary. STepLib aims to manipulate both spatiotemporal and multimedia data. Currently, the STepLib model supports maps, still images, video, audio and documents, as first class objects. This allows not only for the support of storage and presentation capabilities, but also for indexing and searching of these complex data types. Metadata are used in the model to represent semantic abstraction of the underlying geo-objects, based on different layers of abstraction. Spatiotemporal operations are performed at various levels, and data type specific operations are available for improving searching on multimedia data.
