Remote sensing is a common tool in agriculture for crop classification and monitoring. Globally available high resolution imagery makes it possible to delineate individual field boundaries, which can serve as a foundational data set for secondary agricultural analysis. For the most accurate results, the methods employed in field classification and delineation are often fine-tuned to the agricultural conditions within the local geographic context of interest. This fine-tuning, however, can make it difficult to implement the same models in other locations to the same degree of accuracy. While these locally-tuned examples provide valuable insight into developing crop classification systems, a classification model that is applicable at larger spatial scales (e.g. national, global) requires a different approach. This paper proposes a geographically scalable workflow that integrates unsupervised machine learning, local knowledge, and emerging deep learning techniques to enable accurate, flexible field delineation. This approach achieved 88.1% overall accuracy in classifying agricultural fields for the state of Minnesota without relying on any external training data. This workflow can serve as a prototype for globally scalable field mapping.
