Pretrained Weights
^^^^^^^^^^^^^^^^^^

TorchGeo provides a number of pre-trained models and backbones, allowing you to perform transfer learning on small datasets without training a new model from scratch or relying on ImageNet weights. Depending on the satellite/sensor where your data comes from, choose from the following pre-trained weights based on which one has the best performance metrics.

Sensor-Agnostic
---------------

These weights can be used with imagery from any satellite/sensor. In addition to the usual performance metrics, there are also additional columns for dynamic spatial (resolution), temporal (time span), and/or spectral (wavelength) support, either via their training data (implicit) or via their model architecture (explicit).
