Abstract: Location systems and methods for locating paint and other markings on a surface are described. More specifically, but not exclusively, the disclosure relates to smart paint stick devices and methods for locating and marking buried utility lines or other buried objects. One system for locating a buried object may include a buried object locator and paint stick. The locator may include a tracking component for detecting a location of a buried object. The paint stick may be configured to cause a paint container to dispense paint at a first position associated with the location of the buried object. The paint stick may include a position determination component for transmitting one or more range vector signals that are detected by the tracking component. Sensors may be used to determine when paint is dispensed from a paint container, and to determine a color of the paint or a type of a marking.

Abstract: Methods and systems for updating digital maps by refining map feature positions and improving map position accuracy are disclosed. One embodiment includes identifying a point of interest's position data and updating the map data within a map region surrounding the point of interest.
