This course is an applied study of deep learning methods for extracting information from geospatial data, such as aerial imagery, multispectral imagery, digital terrain data, and other digital cartographic representations. We have provided background and conceptual information in the form of lecture modules (prefixed with "L"), video examples using ArcGIS Pro (prefixed with "V"), and coding examples using Python and PyTorch ("Prefixed with "E"). We primarily focus on convolutional neural networks (CNNs) and semantic segmentation methods. As we continue to expand the course, we plan to add more materials associated with instance segmentation, generative models, autoencoders, and variational autoencoders.
The first column below provides links to the data used in the examples, additional examples stored in a GitHub repo, and PDF versions of the lecture modules. The other two columns contain links to the lecture modules and ArcGIS Pro and PyTorch examples. The lecture modules are fully transcribed via the Notes tab. These notes have also been included in the PDF versions of the lectures. Note that working through many of the examples, especially those relating to CNNs and semantic segmentation, will require access to a GPU. We have also provided trained models along with the class data if you are unable to train models with your available resources. We have also included the PyTorch examples as Quarto documents along with the data.
It is assumed that you have prior knowledge of coding in the Python language. The R language is also used but to a lesser extent. If you do not have experience coding, please take a look at our Methods in Open Science and/or Open-Source Spatial Analytics (R) courses, which explore coding in Python and/or R.
After completing this course you will be able to:
If you have any questions or suggestions, feel free to contact us. We hope to continue to update and improve this course.
