Claim:
1. A method of operation executed by a navigation system, the method comprising: determining a location indicator within a geographic area, the location indicator representing a physical location of a device detected by a global positioning system within the geographic area representing a region traversed by a user with the device; detecting an inanimate object location by capturing an obstruction with a capturing sensor, the obstruction being an obstacle hindering a transfer of a global positioning system signal, wherein the inanimate object location represents the physical location of the obstruction; determining a distance by measuring an amount of space, with the capturing sensor, between the inanimate object location of the obstruction and the physical location of the device; determining a traversal position based on the distance for detecting the physical location of the device without the global positioning system; determining a position error representing an inaccuracy of the location indicator based on whether a distance difference between the location indicator and the traversal position is greater or less than a position threshold; determining an adjustment factor based on an error magnitude of the position error; and generating an update position with a control unit based on updating the location indicator with the adjustment factor for displaying on the device.
