Abstract :
A land cover classification method using a neural network is applied for the purpose of utilizing spatial information. The adopted model of the neural network has a three layered architecture, and the training method of the network is the back-propagation algorithm. Co-occurrence matrices, which are extracted from original image data, are used for the input pattern to the neural network. To evaluate the method, classification was conducted with this method for images from the Landsat TM and SPOT HRV. Obtained classification accuracies were 7-12% higher than that of the conventional pixel-wise maximum likelihood method based on spectral information
