Use cases

We plan to implement the following list of use cases:

• UC1 – Annotating regions on high-resolution map images: the high-resolution zoomable maps presented to maphub users are, in fact, compound Web resources comprising a set of image tiles and a metadata descriptor file. Users should have the possibility to annotate complete maps or map regions.

• UC2 – Georeferencing maps: users will have the possibility to mark places on maps and link those places to geographical Web resources (e.g., Geonames ). Using this information, it is possible to establish a correspondence between a map’s image coordinates and real world geographic coordinates.

• UC3 – Annotation augmentation: while the user is creating textual annotations on a map or map region, maphub automatically proposes resources from the Linked Data Web (e.g., DBpedia), which may be semantically related to the annotation and therefore also to the annotated map. Users should have the possibility to accept or reject link proposals and the system could possibly learn from this behavior. Interoperability Use Cases

• UC4 – Mapping Sites Integration: maphub will provide the possibility to display user-contributed shapes, place marks and lines from end-user mapping sites such as Google (My)Maps or OpenStreetMap. Suitable integration points will be provided that allow users to import and view their personal geo-information (sights, walks, hiking routes, etc.) on historic maps. Vice-versa, users will have the possibility to discover historic maps in these mapping sites.

• UC5 – Map Annotations on Mobile Clients: it should be possible to view and create map annotations on Web-enabled mobile clients (e.g., iPad, Google Android platform). For location-enabled mobile devices, maphub should also provide the ability to search maps based on location, and to overlay the current location on the historic map
