Claim:
1. An apparatus comprising: a memory configured to store a first plurality of Radio Frequency (RF) signal strength values that are mapped to known locations within a broadcast area served by a plurality of RF transmitters, and to store a second plurality of RF signal strength values that are not mapped to known locations within the broadcast area; and electronic circuitry communicatively coupled to the memory that is configured to estimate locations within the broadcast area where the second plurality of RF signal strength values were measured based on the first plurality of RF signal strength values and their corresponding known locations; the electronic circuitry configured to calculate an uncertainty for the estimated locations, and to identify an estimated location having a highest uncertainty; the electronic circuitry configured to direct a measurement device to measure an RF signal strength value at a known location within the broadcast area that corresponds with the estimated location, and to add the RF signal strength value to the first plurality of RF signal strength values to reduce an uncertainty in subsequent estimates of locations within the broadcast area where RF signal strength values were measured.
