The FTW benchmark data includes all the chips and associated imagery to train field boundary models. This repo is starting as a demonstration of how to organize it, and will evolve to be alpha and beta releases of the 2.0 dataset. This catalog is a 'git-backed' Portolan catalog, backed by https://github.com/fieldsoftheworld/benchmark-data-catalog
