Abstract
A system and method for determining bounds of a geographical area, such as a city, metropolis, region (e.g., state) or country. From a set of coordinates within the area (e.g., latitude/longitude coordinates), a grid of relatively small cells of geographic data is overlaid upon those coordinates and associated with the area. Each initial cell is iteratively replaced with a larger cell that encompasses the initial cell until the replacement cell intersects a cell associated with some other geographical area or some other boundary condition is met (e.g., a threshold number of replacements).
