Multiband radiometer for field research

摘要: To develop the full potential of multispectral data acquired from satellites, increased knowledge and understanding spectral characteristics specific earth features is required. Knowledge relationships between important parameters surface can best be obtained by carefully controlled studies over areas, fields, or plots where complete describing condition targets attainable frequent, timely measurements obtained. The currently available instrumentation systems are either inadequate too costly to obtain these data. Additionally, there a critical need for standardized acquisition calibration procedures ensure validity comparability
