A convolutional neural network (CNN) approach produced highly accurate vegetation classifications. Hyper-spectral datasets (e.g., AVIRIS) were most useful for our machine learning approaches. Accurate and high-resolution datasets generated using our approach are needed for Arctic models.
The Objective:
- Develop high-resolution maps of Arctic vegetation using machine learning and satellite imagery (e.g., NASA).
New Science:
- A convolutional neural network (CNN) approach produced highly accurate vegetation classifications. Hyper-spectral datasets (e.g., AVIRIS) were most useful for our machine learning approaches. Accurate and high-resolution datasets generated using our approach are needed for Arctic models.
The Impact:
- Remote sensing products were combined and maps of vegetation distribution evaluated against field data for the Seward Peninsula
