Enhancement of land-use change modeling using convolutional neural networks and convolutional denoising autoencoders
This work addresses land-use change prediction for environmental and urban planning, but it is incremental as it builds on existing CNN and CA methods.
This study tackled land-use change modeling by applying convolutional neural networks and convolutional denoising autoencoders to capture neighborhood effects from satellite images, improving performance over models using only geographical features, with conv-net generally outperforming CDAE-net except in noisy data conditions.
The neighborhood effect is a key driving factor for the land-use change (LUC) process. This study applies convolutional neural networks (CNN) to capture neighborhood characteristics from satellite images and to enhance the performance of LUC modeling. We develop a hybrid CNN model (conv-net) to predict the LU transition probability by combining satellite images and geographical features. A spatial weight layer is designed to incorporate the distance-decay characteristics of neighborhood effect into conv-net. As an alternative model, we also develop a hybrid convolutional denoising autoencoder and multi-layer perceptron model (CDAE-net), which specifically learns latent representations from satellite images and denoises the image data. Finally, a DINAMICA-based cellular automata (CA) model simulates the LU pattern. The results show that the convolutional-based models improve the modeling performances compared with a model that accepts only the geographical features. Overall, conv-net outperforms CDAE-net in terms of LUC predictive performance. Nonetheless, CDAE-net performs better when the data are noisy.
