A mapping method for identifying density which includes determining at least one geographical boundary about a geographical location of interest, the at least one geographical boundary is free of any self-intersections, dividing the at least one geographical boundary into a plurality of regions of interests, each region of interest is defined by a start point and an end point on the at least one geographical boundary, wherein the end point associated with one region of interest coincides with a start point of a neighboring region of interest wherein the region of interest falls within the at least one geographical boundary, for each of the plurality of regions of interest, calculating at least one parameter of interest within the region of interest, and graphically presenting a segment between the start point and the end point on the at least one geographical boundary with a line thickness proportional to the calculation results.
