Abstract
A server including data loading, data analysis, transformation and cleaning (TAC), and position estimation modules. The data loading module loads original position data (OPD) sets. OPD points of the OPD sets refer to positions of a wireless device in communication with a wireless station. The data loading module loads each OPD set based on an identifier of the wireless station in a corresponding one of the OPD sets. The data analysis module: determines an overall bounding area based on the OPD points; divides the overall bounding area into minimum bounding areas; and assigns the OPD points to the minimum bounding areas. The TAC module: transforms and cleans some of the OPD points to provide updated points, such that the updated points have a less number of points than the some of the OPD points. The position estimation module estimates a position of the wireless device based on the updated points.
