    Abstract: A system and method is provided for determining the location of a device based on image of objects captured by the device. In one aspect, an interior space includes a plurality of objects having discernable visual characteristics disposed throughout the space. The device captures an image containing one or more of the objects and identifies the portions of the image associated with the objects based on the visual characteristics. The visual appearance of the objects may also be used to determine the distance of the object to other objects or relative to a reference point. Based on the foregoing and the size and shape of the image portion occupied by the object, such as the height of an edge or its surface area, relative to another object or a reference, the device may calculate its location.

    Abstract: Interactive geographic information systems (GIS) and techniques are disclosed that provide users with a greater degree of flexibility, utility, and information. A markup language is provided that facilitates communication between servers and clients of the interactive GIS, which enables a number of GIS features, such as network links (time-based and/or view-dependent dynamic data layers), ground overlays, screen overlays, placemarks, 3D models, and stylized GIS elements, such as geometry, icons, description balloons, polygons, and labels in the viewer by which the user sees the target area. Also, “virtual tours” of user-defined paths in the context of distributed geospatial visualization is enabled. Streaming and interactive visualization of filled polygon data are also enabled thereby allowing buildings and other such features to be provided in 3D. Also, techniques for enabling ambiguous search requests in a GIS are provided.

    IPC: H04L12/26

    Abstract: Aspects provide methods, systems, and recording mediums for determining compliance with a location data protocol including a threshold minimum number of location data reports by users. As an example, fictitious user data including a set of locations may be generated. The set of locations may include at least one location that does not meet the threshold minimum number of location data reports by users of the location data protocol. The fictitious user data may be provided to a location data processing system that processes user location data and outputs output data including a list of locations. The output data is received and used to determine whether the at least one location is included in the list of locations. When the at least one location is included in the list of locations, it may be determined that the location data processing system has not complied with the location data protocol.

    Abstract: Feature selection is provided for geometry data in an image-based based location determination. For example, one or more computing devices, may receive information collected at a particular area. The one or more computing devices may identify one or more features and associated locations from the received information. The identified one or more features may be ranked according to relative uniqueness among the identified one or more features. A set of geometry data for locating a mobile device at the particular area is generated based on selected ones of the ranked features and the associated locations.
