A study area defines the trade area boundaries that are analyzed in a report. Concentric radii around a site are unlimited in size and number. Sectors divide a study area into segments, like a pie that has been cut into pieces. Polygons are areas that are defined by a series of line segments. Polygons may have as few as three points or as many as several thousand.
Polygons are most effective when a map of the study area is provided.
Corridors are equal bandwidths on both sides of a line. Cuts are lines that subdivide a ring or polygon based on the proximity of competitor sites.
