The suitability of selected satellite vegetation indices for estimating the condition of cereals in Poland was investigated. The indices presented here were derived from the data stored in INFOSAT database, which was created at the Institute of Geodesy and Cartography. INFOSAT contains data from processed satellite images acquired by NOAA AVHRR scanner. The methods applied in the database generation and in the calculation of vegetation indices were analysed in view of their applicability to the inference on crops condition over a large area. Presented results of statistical analysis indicate significant relations between the production of cereals and indices based on NDVI.
