Claim One:
1. A spectrum analysis method comprising: obtaining, at computer system, a simulated spatial distribution of spectral power for a geographic region, the simulated spatial distribution based on a simulation of wireless signal propagation in the geographic region; obtaining, at the computer system, a measured spatial distribution of spectral power for the geographic region, the measured spatial distribution based on measurements by wireless sensor devices in the geographic region, each wireless sensor device configured to provide a local spectral power measurement based on wireless signals detected by the wireless sensor device; comparing, by operation of the computer system, the simulated spatial distribution with the measured spatial distribution; and modifying the simulated spatial distribution based on the comparison, wherein modifying the simulated spatial distribution comprises: identifying, for a plurality of locations in the geographic region, differences between the simulated spatial distribution and the measured spatial distribution; generating an error mesh for the geographic region by spatially interpolating the differences for the plurality of locations; and modifying the simulated spatial distribution based on the error mesh.
