Abstract: A system and method are disclosed for incrementally updating an existing digital map of a client device in a digital map update system. The digital map update system comprises, for each of one or more baseline digital maps, at least one digital map update repository comprising data which may be communicated to one or more remote client devices for use by the or each remote client device in incrementally updating an existing digital map of the device. Each repository includes one or more digital map forward update journals in respect of a respective given version of the baseline map to which the digital map update repository relates. The forward update journal comprises data indicative of a set of one or more incremental updates that may be used to update the given version of the baseline map to a later version.

Abstract: Parking lot (18, 20) locations and geometries are discerned from probe data (22) and integrated with a digital map (12) for use in navigation and other map-related activities. The steps of this invention include: identifying the positions in the probe data (22) where cars are probably parked, detecting the positions of parking lots (18, 20), determining the extension and shape of the detected parking lots (18, 20), and adjusting the parking lots (18, 20) into the road network (14). Optionally, the parking lot (18, 20) can be classified and additional attributes computed. Finally, a topological connection of the parking lot (18, 20) is made to the road network (14) during which entrances (34) and exits (36) are identified.

Abstract: A system and method for providing a digital map database wherein multiple instances of geocoded objects pertaining to points of interest (POI) and/or three-dimensional (3D) objects contained within one or more building blocks are compared to find undesirable duplicate geocoded objects. Cross-referencing information is stored and preference information about which geocoded object or object property/attribute should be used is assessed to determine priority for selection or presentation on the display screen of a navigation device or other suitable computing device. Cross-references can be pre-calculated at compile time or calculated on-the-fly by the navigation application at run time and may be persistently stored in dedicated data structures. When duplicate geocoded objects are found, only the most accurate information or a super set of (attribute) information is used by applications or presented to a user thereby preventing confusion.

Abstract: A method is disclosed for combining a first partition from a first digital map database and a second partition from a second digital map database, wherein the first and second digital map database are associated with a coordinate reference system, wherein the first and second partition include an interaction with each other in a common region in the first and second digital map database.

Abstract: Method for generating a location reference and method for mapping information to a position within a digital map database are disclosed. At least one embodiment of the invention relates to a method for generating a location reference for mapping information to a position within a digital map database. The digital map database includes map objects having unique map object references associated therewith. The method includes: selecting a map object in the digital map database based on the information, selecting a unique map object reference of the selected map object, generating the location reference including the unique map object reference of the identified map object. The method further includes: determining a relative position of the position in the digital map database the information relates to with respect to the selected map object, and the location reference further includes the relative position.

Abstract: A digital map with line features is stored on a storage medium into parcels, each covering a certain area of the map. A parcel has around it standard border a border region bounded by an inner border and an outer border. A line feature crossing the standard border between two neighboring parcels is only divided into two new line features if it completely crosses the border region, i.e. if it crosses the outer border of both neighboring parcels.

Abstract: An arrangement for connecting two parts of a fluid system, preferably an aseptic system, by which the pressure gradient acts from the outside to the inside. The one system part carries an O-ring in a groove open to the other system part and open radially outwardly and the other system part is pressed against the O-ring by an axial holding device. To avoid dead space, in which bacteria could deposit, a space formed by the O-ring, the two system parts and the axial holding device is provided with a communication to the surroundings.
