- Abstract
- The aim of this study was to examine if Landsat TM data could be used to :
(I) estimate autumnal rape seed area
(II) study the wintering of autumnal rape seed
(III) estimate autumnal rape seed yield.
The study took place in the province of Scania, Sweden. Two Landsat TM scenes, registrated 85-11-08 and 86-05-03, were included. The scenes were radiometric and geometric corrected in an image processing system, DIPIX ARIES III. Visual interpretation techniques were used. Both visual and digital interpretation techniques (i.e. Maximum likelihood classification of the scenes at DIPIX ARIES III) were used when studying the wintering of autumnal rape seed. A statistical system MINITAB, available at the MicroVax II system, were used to... (More) - The aim of this study was to examine if Landsat TM data could be used to :

Both visual and digital interpretation techniques (i.e. Maximum likelihood classification of the scenes at DIPIX ARIES III) were used when studying the wintering of autumnal rape seed. A statistical system MINITAB, available at the MicroVax II system, were used to evaluate the results. Correlation between estimated rape seed area and field data was 0.880. The number of fields that have wintered were underestimated with both visual and digital interpretation. The visual interpretation showed the better result. Through analysis of variance, a correlation between satellitedata and rape seed yield was indicated. For an operational applicability further investigations are necessary. (Less)
