Abstract :
Presents the results of a study where a self organised map (SOM) was used to classify a NOAA-AVHRR satellite image. The neural network was fed with both spectral and spatial features. All five bands were used to extract the median and range of small “floating” subwindows as well as the average entropy and the range of average entropy. This procedure resulted in a vector with four components per band for each pixel. These vectors were processed by the neural network to obtain a projection into a two-dimensional Kohonen map
