SCYM Maize Yield Maps (Low Resolution) from Deines et al. 2021, Lobell et al. 2020

<p>Annual maize yield maps for the US Corn Belt for 1999-2018, aggregated to 10 km resolution. Yield maps are produced with the SCYM methodology at 30 m resolution using Landsat satellite data. The original high resolution yield maps are aggregated to a 10 km grid resolution to preserve privacy.</p> <p>Dataset creation is described in <a href="https://doi.org/10.1016/j.rse.2020.112174">Deines et al., 2020</a>&nbsp;in Remote Sensing of Environment (open access). The 2008-2018 map dataset described therein was extended back to 1999 for <a href="https://doi.org/10.1038/s43016-020-00165-w">Lobell et al. 2020</a>&nbsp;in Nature Food (<a href="https://rdcu.be/b9cXQ">read-only accessible version</a>). Maps for 2008-2018 use the USDA&#39;s Cropland Data Layers to identify maize pixels; maps for 1999-2007 use the Corn-Soy Data Layer produced by <a href="https://www.nature.com/articles/s41597-020-00646-4">Wang et al. 2000</a>&nbsp;(data + manuscript are open access).</p> <p><strong>Metadata</strong></p> <p>Yield values are provided in metric tons/hectare.&nbsp;</p> <p>No Data value = -999 (grid cells outside of the study area + cells with &lt;1% coverage of SCYM 30 m yield maps)</p> <p>Map projection: EPSG:5070, CONUS Albers Equal Area</p> <p>&nbsp;</p> <p>&nbsp;</p> <p>Preferred citation(s):</p> <p>Deines, J.M., R.
