Circles and driving areas on US ZIP and county maps
The Radial Circles and Distance/Time tools also work on individual and combined US five-digit ZIP and county maps. Choose straight-line circles for an approximate radius, or driving areas when roads and travel time matter.
Add a straight-line radius
Open Radial Circles, place the center on the map, then choose the number of rings and miles between them. US ZIP and county maps use a state-aware scale, including combinations; treat the circles as approximate distances, not exact driving routes. You can color whole ZIP or county areas within them if useful.
Build a road-travel area
Open Distance/Time, search for a starting place or click the map to put down a flag. Choose miles or driving minutes, set the limit and bands, then press Create. This uses the road network and needs active access; it is different from drawing radial circles.
Color ZIP areas or counties from coverage
The coverage-colouring buttons can assign whole ZIP or county polygons using their centres. A polygon touching the edge is not automatically included if its centre is outside. Choose Add to existing to keep other territory colours, or Replace colouring only when you want to start over.

Three rings, 50 miles apart, centered in Kansas. The outer ring is approximately 150 miles from the center; these are not road-travel distances.
