Agricultural monitoring assessment based on low spatial and high temporal resolution satellite: A comparison of AVHRR and MODIS

In this context, we have assessed the potential of using low spatial resolution satellites in agricultural monitoring comparing long-term NDVI time series from AVHRR and MODIS (1 km and 250 m), analyzing more specifically areas of sugarcane production in the southeastern region of Brazil, the southern hemisphere. The methodology employed in this work is based on time series mining and statistical methods, such as Pearsons correlation and linear regression. Results showed that there is a strong correlation among AVHRR with MODIS 1km or MODIS 250m. Experiments were applied in a region with large areas of sugarcane fields.
