Expand Torchgeo_FCN_Full.ipynb use more Chesapeake datasets

Issue

The Torchgeo_FCN_Full.ipynb is supposed to be a demonstration of using a wide range of Chesapeake dataset but does not currently do so.

Solution

Expand Torchgeo_FCN_Full.ipynb to use more Chesapeake datasets.

It appears that the ChesapeakeCVPR dataset class is still quite buggy. microsoft/torchgeo#619 highlights issues with the patch sizes misaligning during sampling. Supposedly, this is fixed in microsoft/torchgeo#992 by sampling a double the patch size then cropping down in ChesapeakeCVPRDataModule.

However, I get an error in the cropping:

AssertionError: Crop size must be smaller than input size. Got (198, 106) and (128,
128).

This occurs whether I set patch_size=128 or patch_size=256. I may lodge an issue on torchgeo to see if they can assist and fix this bug.
