Remote sensing based system for crop monitoring

Remote sensing based system for crop monitoring

Grant No 9T12 E00415 (IGIK G-37)
Project leader: prof. dr hab. Andrzej Ciołkosz
01.07.1998 - 30.06.2001

The aim of the research project was to prepare a system, which enables to use information derived from satellite images for operational monitoring of crop conditions within agricultural land in Poland. As a result of the works INFOSAT database was created, in which data concerning spectral reflectance and temperature registered by NOAA AVHRR scanner were stored. At this database albedo values and radiation temperature values were gathered for each 10-day period between 1992 and 2000. On the basis of these data the following indices were calculated for each period and for each administrative unit: Normalized Difference Vegetation Index - NDVI, Vegetation Condition Index - VCI, Temperature Condition Index - TCI and Plant Development Index - WWR.

These indices characterizing crop conditions were compared with agrometeorological information. Detailed analysis of drought conditions in Poland in 1992 was carried out on the basis of agromet data and simulation model prepared by IMUZ. Next results of this analysis were compared with spatial distribution of TCI index; the results revealed, that using satellite remote sensing areas affected with drought can be detected and monitored.
