DISAGGREGATING AGRICULTURAL STATISTICS USING NOAA-AVHRR NDVI

Linking the results of remote sensing with production statistics to cr ate land-use maps is problematic. This article presents a technique th at integrates two significant data sets relating to agricultural land- use, namely, survey-based production statistics and vegetation growth profiles derived from satellite data. The article describes an applica tion of this technique in which production data from an administrative survey ar used to constrain tghe classification of NDVI profiles of l and cover classes. Because the technique reallocates aggregated produc tion statistics consistent with low-resolution imagery and with limite d ground control information, it is a particularly cost-effective meth od of extensive land-use mapping.
