Various methods, systems and apparatus for displaying content associated with a point-of-interest (“POI”) in a digital mapping system, are disclosed. One such method may include detecting a change in the zoom level of an electronic map displayed on a computing device, determining if the new zoom-level is at a pre-determined zoom level (e.g. at maximum zoom), identifying a POI on the map, retrieving content associated with the POI (“POI content”) and displaying the POI content. The method may further include detecting a change in the zoom, or pan, of the digital map while POI content is displayed, and removing the POI content in response. One apparatus, according to aspects of the present invention, may include means of detecting a change in the zoom level in a digital map displayed through an application (e.g. a web browser, an application on web-enabled cellular phones, etc., displaying a map generated by a service such as Google Maps®, Yahoo! Maps®, Windows Live Search Maps®, MapQuest®, etc.) on a computing device (e.g. personal computer, workstation, thin client, PDA, cellular phone/smart phone, GPS device, etc.) means of identifying a POI at the pre-determined zoom level, means of obtaining content associated with the POI, and means of displaying the POI content. POI content may be retrieved from a database (e.g. internet-based database); or, in an alternate embodiment, gathered by crawling websites associated with the POI. In one embodiment, POI content may be displayed as an image (e.g. a PNG file, GIF, Flash® component, etc.) superimposed on the digital map (e.g. as an overlay object on the map image.) In alternate embodiments, POI content may replace the digital map and may contain links to other content.

A database receives location information about a moving object. Using the destination of the object and an electronic map, the database finds a projected path for the moving object. From the projected path, the database computes a trajectory. The trajectory may be used to estimate past and future positions of the moving object. The moving object may send location updates to the database when its actual location differs from its anticipated location by more than an uncertainty threshold.

Locality indexes are presented for use with electronic maps and databases. Each geographic feature in a geographic database is associated with locality names from various locality name sources. Context-sensitive tokenizing, normalizing, optimizing and matching of locality names eliminate duplicate and variant locality names, while preserving meaningfully different names. A locality names table includes the parsed representation of each locality name and other associated information, and a primary token for indexing is identified. A main source mask is created by allocating a bit for each locality name source used in the method. A separate source mask is stored for each geographic feature associated with a locality, a bit set for each source in which the locality can be found. Locality names associated with each geographic feature are indexed in a table of geographic features in order of prevalence for use in a given application.

A system is disclosed for warping models made from geometric objects, such as electronic maps, to correct local distortions in the models without compromising model topology. A set of transformation functions are derived from relationships between points in a first model that match points in a second model. The transformation functions are then applied to the points in the first model to generate a new model with reduced distortion. In order to provide for reducing local distortions, warping is applied to selected corresponding regions of the first model and the second model by triangulating these regions and generating transformation functions for each corresponding pair of triangles. Topology preservation is achieved by identifying matching points in the first model and the second model that have a potential for causing topology deviations. Such matching points are then excluded from the process of developing transformation equations to be used in the warping process. Matching points with potential for causing topology deviations are identified by triangulating matching points in the selected regions of the first model and the second model and analyzing the resulting triangles.
