What is granite-geospatial-canopyheight?
The granite-geospatial-canopyheight is an advanced AI model designed to predict canopy heights from satellite imagery. It utilizes the Harmonized Landsat and Sentinel-2 (HLS) L30 optical satellite imagery and has been fine-tuned using training data from the Global Ecosystem Dynamics Investigation (GEDI) L2A across 15 different global biomes.
Implementation Details
The model is built on a Swin-B transformer backbone, chosen for its superior characteristics including smaller patch size for higher resolution, efficient windowed attention, and hierarchical merging capabilities. It employs SimMIM self-supervised learning for pretraining and uses a UPerNet adapted for pixel-wise regression during fine-tuning.
