Project: Identification and Graph Structure of Rivers

Goal of the project:

The goal of the project was to identify rivers on maps and satellite images, and to calculate each river’s graph structure.

Summary of work:

We implemented a function that uses street maps to highlight bodies of water on satellite images. We also implemented a function to calculate the graph structure of the rivers at any given location.

Results and future work:

We would like to implement a random river generation function and identify rivers from satellite photos using a neural network. To improve the quality of highlighting/graphs, we would like to remove signs from street maps using a feature in Mathematica 11.2.
