Abstract: A navigation system and method for resolving discrepancies between a reported position and route data is presented. Based on a reported position, the navigation system identifies prospective road segments within a radius of the reported position. For each road segment, the navigation system generates a series of scores according to various attributes, including the current heading, current speed, proximity of reported location to the prospective road, and the like. Historical scores are also generated based on historical information, i.e., previous navigation device locations. Scores are normalized such that they can be compared, and optionally weighted according to particular implementation details. After scores have been generated for each prospective road, the prospective road, and its determined location, with the best score is selected as the resolved, actual location.

Abstract: A method of processing seismic data comprises processing data representative of the acceleration wavefield so as to obtain information about the earth's subsurface direct from the seismic data representative of the acceleration wavefield. In conventional techniques for processing seismic data representative of the acceleration wavefield the data are transformed to the velocity domain at an early stage in the processing. The invention enables the transform step to be eliminated, thereby simplifying the processing and eliminating the risk that the transform might degrade the data. Furthermore, the increased sensitivity at high frequencies of a typical acceleration sensor compensates for the low-pass filter effect of the earth.

In one embodiment, the data will be used to compute a virtual VSP, checkshot, or similar survey by cross correlating a trace recorded at the surface with a trace recorded at depth. In another embodiment, the surface and well sensors will be permanently emplaced and repeated recordings over time will be used to form a time-varying (4-D) image of the subsurface.
