There is disclosed a system and method for geotagging objects on a mobile handheld communication device. In an embodiment, the method comprises: providing a user interface with a plurality of user selectable options for obtaining geographic location coordinates; receiving a user selection of one of the plurality of options; and tagging an object with the geographic location coordinates obtained from the selected one of the plurality of options. In another embodiment, the method may further comprise obtaining from an active global positioning system (GPS) module the geographic location coordinates for a current location to tag the object. The method may further comprise providing previously saved geographic location coordinates to tag the object. The object may be an image object.

System and method for selecting a geographic location to associate with an object

In displaying a map on a wireless communications device, a method is provided that resolves labelling of sharp curves. The method entails a determination of whether a curvature of a map element associated with the map feature exceeds a predetermined threshold (e.g. whether a rate of change in slope of a path or the change in angular orientation of each successive character in the label exceeds a threshold that is a function of zoom level. If the curvature exceeds the threshold, the label is rendered on the map in a new map location that avoids the map location where the curvature exceeds the threshold.

A method of displaying a map on a wireless communications device, the method comprising obtaining map data for rendering the map to be displayed on the wireless communications device and determining a zoom level of the map. If the zoom level of the map exceeds a predetermined zoom level, corrected map data is generated by applying a fixed spherical correction factor to the map data. If the zoom level of the map does not exceed the predetermined zoom level, the corrected map data is generated by computing a spherical correction factor based on a latitude of the map. The method also includes rendering the corrected map data to display the map on a display of the wireless communications device.

Real-time spherical correction of map data

A wireless communications device generates a message from a map application to enable a recipient of the message to view a location on a map. After a user selects a location to be sent to the recipient, the map application determines location information associated with the location and generates the message to be sent to the recipient. The message contains a link to enable the recipient to download the map showing the location and further contains the location information embedded as text within the message. The map application can determine whether the location is based on a GPS position fix, whether it is a Point of Interest or whether it is part of a map route. In each case, predetermined text is automatically embedded in the message to convey the location information to the recipient.

Method of e-mailing a map location using predefined context-sensitive messages

A method of displaying a map on a wireless communications device includes steps of obtaining map data for rendering the map to be displayed on the wireless communications device, generating corrected map data by applying a spherical correction factor to the obtained map data, and rendering the corrected map data to display the map on a display of the wireless communications device. The spherical correction factor corrects for map distortions that occur at northerly (or southerly) latitudes. Since the spherical correction factor is a simple correction to a 3&#xd7;3 transformation matrix, this spherical correction can be easily applied without taxing the CPU limitations of small handheld devices.

A method of displaying a map on a wireless communications device includes obtaining map data for rendering the map to be displayed on the wireless communications device, the map data including label data for rendering labels on the map. The device generates a collision-avoidance array representative of the map to be rendered for testing potential label positions prior to actually rendering the labels on the map. The collision-avoidance array is populated by provisionally designating, for each successive label to be rendered, a label space in the collision-avoidance array that corresponds to a map space that is to be occupied by the label on the map. The device then determines whether each successive label to be rendered collides in the collision-avoidance array with any previously designated label spaces. If no collision exists for a given label, the label can be rendered on the map.

Real-time collision avoidance for map labels and symbols

A method of stitching converging path segments to aesthetically label Y-intersections, path bifurcations or splits in roads or the like entails determining which pair of adjacent path segments subtend the largest angle. The path segments subtending the largest angle are reconstructed (stitched together) and a single instance of the label is then rendered along the reconstructed path. Although this stitching can be performed on the client device, pre-stitching server-side is even more efficient in terms of economizing over-the-air bandwidth and onboard processing resources.

Method for stitching multiple converging paths

A system and method of controlling user interface features of a web application is provided. The system comprises a collection of user interface control elements, a collection of skin templates comprising extensible markup language based markup contained as children of a container element, and a collection of control element instructions for performing actions associated with the control elements. Each control element comprises a namespace, common attributes for defining graphical features of the control element and for associating the control element with the internal state of the core control element, other attributes for defining attributes that affect the intrinsic behavior of the control, and a skin template reference attribute for referencing a skin template. Each instruction is associated with a control element.

A system for manipulating a document object model is provided. The system comprises a collection of document object model behavior elements, and a collection of scripts for performing actions associated with the set of behavior elements. Each behavior element comprises a name following a predetermined naming convention, an event attribute for associating the behavior element to an event, and other attributes for describing features of the behavior element. Each script is associated with a behavior element.
