Utilisation of remote sensing data in agriculture drought monitoring
Original language description
Drought preparedness must be an important part of national environmental policies. The monitoring system for covering agricultural drought across the Czech Republic was launched in 2012. It is based on daily step calculations of soil parameters divided into regular grids with the spatial resolution of 500 m. Using freely available data from the MODIS (Moderate Resolution Imaging Spectroradiometer instrument onboard the Terra satellite), the vegetation condition is taken into account as a support tool for vegetation drought impact assessment. Based on the surface reflectance bands the Normalized Difference Vegetation Index (NDVI) is calculated. Consequently, weekly NDVI anomalies are expressed as Percent of Average Actual Greenness (PAAG) in relation tothe average for the period of 2000-2014. The system contains filter algorithms that eliminate the noise in the satellite data mainly due to the cloud effects. The following operation allows for changing crop patterns between seasons and
