30-33 IMPORTANȚA UTILIZĂRII DATELOR DE TELEDETECȚIE PENTRU MONITORIZAREA STĂRII DE VEGETAȚIE A CULTURILOR AGRICOLE
THE IMPORTANCE OF USING REMOTE SENSING DATA FOR
CROP VEGETATION STATE MONITORING
The paper highlights the usefulness of remote sensing data for crops
vegetation state monitoring. For this was chosen as a study area, the
Agricultural Research Station Caracal, located in Olt County, in the Region IV
South-West Oltenia. As remote sensing were used high resolution (Landsat,
spatial resolution 30 m data) and medium (MODIS (spatial resolution of 500 m)
satellite images. They were used to calculate to the following vegetation
indices: the normalized difference of vegetation index (NDVI), normalized
difference water index (NDWI) and normalized difference drought index (NDDI).
For a complete analysis was performed a correlation between the vegetation
indices and main agro-meteorological parameters registered to Caracal
meteorological station (rainfall and soil moisture).
