RESEARCH INTO KEYS FOR THE INTERPRETATION OF SECOND GENERATION SATELLITE IMAGERY, BASED ON RADIOMETRIC LAND USE MEASUREMENTS IN A TROPICAL RICE GROWING REGION
Numerous campaigns of radiometric land use measurement have been completed over a three year period as part of a project for predicting rice production by remote sensing in West Africa (rice growing region of Tamani, in Mali). Exploitation of the results of measurements in visible and infrared light focused on the influence of certain yield parameters on the spectral behaviour of rice plants and the definition of interpretation keys for using the imagery of second generation satellites such as LANDSAT-4 and SPOT. The 1983 campaign (November and December) resulted in the precision and completion of results in the following areas: distinction of three major categories of aquatic vegetation ("standing", "floating" and "wild" rice), during different stages in its growth; value of a lateral view (45 degrees ) in relation to a vertical view in the characterisation of spectral behaviour; spatial variability of spectral responses in a small area at a given moment in the growth cycle of rice plants: the influence of rice variety and growth stage on the degree of spatial variability.
