Abstract

Large size calibration panels are frequently required as reference points for in-scene calibration of remotely sensed spectral data. However, most commercially manufactured calibration panels are costly and sometimes present spectral crossover problems. The panels described in this report are made from readily available fabrics and can provide a lower cost alternative. Four 5.5 x 6.7 m fabric panels that have nominal reflectance of 85%, 38%, 18% or 3% were tested. These fabric panels cost approximately $700 to construct and the materials are available at most hardware stores, which facilitated field panel construction. When properly deployed on a uniform dark-toned surface such as asphalt, gravel, or soil, these alternative panels provide calibration for the entire 0.4 - 2.5 μm spectrum and do not exhibit spectral crossover problems. Remote sensing programs that do not have access to or resources to acquire commercial panels may find these fabric panels a suitable alternative for in-scene calibration.
