AbstractAn approach to generate a 250-meter Canada wide Leaf Area Index (LAI) map using 250-meter MODIS data is described. The full processing chain is introduced. The approach is based on intercalibration of Landsat and MODIS vegetation indices (VI's) combined with LAI-VI's empirical relationships. Preliminary validation over two sites where field work was carried out shows promising results. Intercalibration of MODIS VI's before deriving LAI maps provides up to 65% improvement of the LAI overall accuracy.
