Systems and methods for progressive map maintenance and communication channel selection

A system comprising:

• a hardware-based processing unit;
• and
• a non-transitory computer-readable storage device comprising:
• a resource-availability module configured to cause the processing unit to determine whether a resource scarcity condition exists in connection with providing map data to a mobile navigation unit;
• a hybrid-communication-channel module configured to cause the processing unit to, in response to determining that the resource scarcity condition exists, determine a map-data-delivery arrangement indicating one or more of multiple optional communication channels or channel bands by which to transmit components of the map data;
• and
• a map-data-delivery module configured to cause the processing unit to provide or make available the encoded map data to the mobile navigation unit by way of the communication channel or band determined.
