Spectral response of a plant canopy with different soil backgrounds

Spectral indices in N-Space

Discrimination of growth and water stress in wheat by various vegetation indices through clear and turbid atmospheres

Suitability of spectral indices for evaluating vegetation characteristics on arid rangelands

Soil spectral effects on 4-space vegetation discrimination

Plant canopy information extraction from composite scene reflectance of row crops

As an aid in the interpretation of remotely sensed data from row crops with incomplete canopies, a model was developed that allowed the calculation of the fractions of sunlit so...

Atmospheric effects on radiation reflected from soil and vegetation as measured by orbital sensors using various scanning directions

Ground-measured spectral reflectance data for Avondale loam and drought-stressed and unstressed wheat were converted into digital counts for spectral bands 5 and 7 of the Landsa...

Comparison of measured and calculated hydraulic conductivities of unsaturated soils

Three methods to calculate the unsaturated conductivity of soil from its moisture characteristic were tested. Calculated values were compared with direct measurements of conduct...
