Through the modification and use of a previously developed crop classification model (CCM), which was originally developed to generate historical annual crop cover maps, we hypothesized that such crop cover maps could be generated rapidly during the growing season. Through a process of incrementally removing weekly and monthly independent variables from the CCM and implementing a \u2018two model mapping\u2019 approach, we found it viable to generate conterminous United States-wide rapid crop cover maps at a resolution of 250\u2009m for the current year by the month of September. In this approach, we divided the CCM model into one \u2018crop type model\u2019 to handle the classification of nine specific crops and a second, binary model to classify the presence or absence of \u2018other\u2019 crops. Under the two model mapping approach, the training errors were 0.8% and 1.5% for the crop type and binary model, respectively, while test errors were 5.5% and 6.4%, respectively. With spatial mapping accuracies for annual maps reaching upwards of 70%, this approach demonstrated a strong potential for generating rapid crop cover maps by the 1st\u00a0of September.",
