20110307165 | METHOD FOR CREATING SPEED PROFILES FOR DIGITAL MAPS - Probe data collected at times of low traffic density is analyzed to derive a Raw Road Design Speed Limit (RRDSL, | 12-15-2011 |
20110307166 | METHOD FOR COMPUTING AN ENERGY EFFICIENT ROUTE - Probe data is analyzed to derive Longitudinal Speed Profiles (LSPs) and an Optimal Longitudinal Speed Profile ( | 12-15-2011 |
20120254263 | METHOD AND SYSTEM FOR CROSS-REFERENCING AND DEDUPLICATING OBJECTS IN MULTIPLE MAP BUILDING BLOCKS - 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 ( | 10-04-2012 |
20130245943 | METHOD FOR COMPUTING AN ENERGY EFFICIENT ROUTE - Probe data is analyzed to derive Longitudinal Speed Profiles (LSPs) and an Optimal Longitudinal Speed Profile ( | 09-19-2013 |
20150052149 | METHOD AND SYSTEM FOR CROSS-REFERENCING AND DEDUPLICATING OBJECTS IN MULTIPLE MAP BUILDING BLOCKS - 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. | 02-19-2015 |
20150058305 | METHODS AND SYSTEMS FOR UPDATING A DIGITAL MAP - 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. Each repository also includes one or more digital map reverse update journals for reversing the effects of the or a forward update journal and reverting the later version of the baseline map back to an earlier version. | 02-26-2015 |
20150074068 | METHODS AND SYSTEMS FOR UPDATING A DIGITAL MAP - A digital map update system includes a digital map update server in communication with each one of a plurality of remote client devices for providing data indicative of a set of one or more digital map incremental updates thereto for use by the client devices in incrementally updating respective existing digital maps of the devices. The system comprises two or more digital map update repositories, each update repository comprising data indicative of a plurality of digital map incremental updates for use in incrementally updating a client device, and each being in respect of a different digital map incremental update profile. In use, the digital map update server provides a set of one or more digital map incremental updates from a given one of the update repositories to a remote client device for use by the device in incrementally updating an existing digital map of the device in accordance with the update profile of the given update repository. | 03-12-2015 |
