Mapping Vegetation Communities using Convolutional Neural Networks
Artificial intelligence applied to multiple remote sensing datasets accurately represents shrub distribution across hillslopes at the Kougarok field site.
- Unique training dataset was collected at 30 field plots and the resulting vegetation products evaluated against them for accuracy.
- Fusion of hyperspectral, multispectral, and terrain datasets was performed over a 343 km2 region.
- High-resolution (5 m) vegetation classification map was generated.
- Produced one of the most accurate, high resolution, field-validated vegetation maps for tundra ecosystems.
- Using map now to benchmark field predictions of plant distribution and dynamics across changing Arctic landscapes.
- The authors aimed to develop a deep learning approach (convolutional neural network) capable of generating vegetation maps for the Seward Peninsula in western Alaska.
