A locator represents an area

Maidenhead locators become more precise as characters are added. Decoding reports the center and bounds of that area.

Choose a useful precision

Four characters are coarse, six are common for local position exchange, and eight further narrows the cell. Do not present a decoded cell center as a measured GPS fix.
