Method and system for managing measurements

One embodiment of the present invention separates the region of measurement space (200) into a plurality of sub-regions (211) and calculates a confidence, for reconstruction of an underlying signal within said space, corresponding to each of the sub-regions. This embodiment can then accept measurements (201) from mobile measuring devices within said measurement space and store those measurements if they originate from devices in sub-regions having a confidence below an acceptable value.
