Abstract:
The aim of this research was to try and differentiate some of the important crop cultures in
the Baden-Wuertternberg area by creating crop signatures from the backscatter values of
the different crops from the different test sites. At the end it was also to establish whether
the signatures of one crop (e.g. Maize) collected in one of the test site can be compared or transferred to another test site. This study was done using the TerraSAR-X data, with VV
polarization, which was overlaid with crop fields' ground truth data that was collected from
the fields. Images covering two test sites at Leingarten and Moessingen for the months of
July and August were used. These test sites were located in different climatic regions that
had different sowing times, crop development times and harvesting times as was elaborate in the "Klimaatlas maps". Only radiometric correction was carried out on the images. The speckle noise was not removed or minimized. The crops were classified according to the mean and standard deviation of their backscatter. The results obtained were then compared to results of other researches for checks and accuracies.
