    摘要: Various methods, apparatuses and articles of manufacture may be implemented for use in one or more computing platforms to adaptively provide and/or obtain indoor navigation assistance data (INAD) update(s) for use by a mobile device. An INAD update may, for example, comprise a subset of INAD available for an indoor environment. Such a subset may be determined based, at least in part, on a bounded region in an electronic map of the indoor environment. Such a bounded region may, for example, have a shape and/or a size based, at least in part, on at least one parameter indicative of a motion state of the mobile device.

    摘要: The subject matter disclosed herein relates to a system and method for automatically identifying features in an electronic map. In some embodiments, the method may comprise extracting features, which may include entryways and structural elements, from an electronic map. Based on the extracted features, one or more hallways may be identified in the electronic maps by using one or more line segments, which may extend between at least one entryway and one or more structural elements, and/or at least one entryway and one or more other entryways. The electronic map may be updated with one or more annotations identifying the one or more hallways.

    摘要: The subject matter disclosed herein relates to systems, methods, etc. for creating a routing graph based at least partly on building information. For certain example implementations, a method includes obtaining building information descriptive of at least a portion of a building structure. A grid of points may be superimposed onto the building information. At least one routing graph may be created based at least in part on the superimposed grid of points and the building information. Other example implementations are also described.
