Remote sensing technologies, including satellite imagery and aerial photography, are increasingly being used to characterize and track crop areas, cover crops, riparian vegetation, and pasture-based practices for overall conservation system assessment and tracking. There are several available technologies (free and publicly available, commercial, and state specific) that can be used to track agricultural conservation in the United States. The technologies summarized in this document are a compilation of all the different technologies known to the Hypoxia Task Force (HTF). The first section provides a brief introduction and the second section summarizes all the technologies in a simple table format. The last section of the document provides a one-page summary per technology, including who developed the technology, a brief summary of the technology, what data are available, spatial resolution, scale, how to access the data, benefits of the technology, a brief success story, and resources. The final section lists references used in preparing this document. Finally, Appendix A provides a summary of available technology by HTF state and level of coverage (full/partial).
