1. A sensor for collecting image data for use in an overhead imaging system that moves relative to a region of interest below the overhead imaging system, the sensor comprising: an imaging sensor having an imaging surface area that has an imaging width, the imaging sensor configured to capture image data from the region of interest below the overhead imaging system at a frame capture rate; and a plurality of spectral filters, the spectral filters in aggregate covering a spectral imaging portion of the imaging surface area of the imaging sensor, each spectral filter having a spectral filter width at least substantially the same as the imaging width, and each spectral filter having a spectral filter height greater than or equal to a minimum filter height, wherein the minimum filter height equals a ratio of (1) a rate at which the region of interest appears to move across the imaging sensor due to relative motion of the overhead imaging system with respect to the region of interest to (2) the frame capture rate of the imaging sensor.
