The County of Maui spans nearly 2,400 square miles – encompassing the islands of Maui, Lanai, Kahoolawe, Molokini and Molokai – and provides services that would typically be provided by city governments in the continental United States. Because many services include a geographical element, the county operates GIS and mapping applications to pinpoint the location of water lines, provide accurate information for real estate tax calculations, and enable a host of other essential capabilities.
