Project: Predicting the Scale of Satellite Images Using Neural Networks

Goal

Many interesting projects have been done with satellite images using neural networks, such as semantic image segmentation for finding roads and homes. In this project, we are taking a similar and broader look at satellite images by using a 50-layer convolution neural network (CNN) to predict the scale of satellite images.

Main Results in Detail

After failing to find the right dataset for the project on the internet, I generated the dataset (satellite images) in the Wolfram Language using GeoImage. The dataset was focused on only three cities (Dallas, Chicago and Houston) with a scale of 0.06 miles to 10 miles. Training on an Amazon EC2 GPU took 13 hours with 33,162 training, 4,075 validation and 1,830 testing satellite images. After the training, I got a 0.08 mean absolute error (MAE), which means that the neural network can predict up to 92% correctly.

Future Work

Train the neural network with:

  • 1. More satellite images.
  • 2. Different countries and broader ranges.
