Google Earth Engine—美国西部11个州的灌溉状况进行的年度分类(即30米),1986年至今。四个等级的分类(即灌溉、旱地、非耕地、湿地)


IrrMapper is an annual classification of irrigation status in the 11 Western United States made at Landsat scale (i.e., 30 m) using the Random Forest algorithm, covering years 1986 - present. While the ​​IrrMapper paper​​ describes classification of four classes (i.e., irrigated, dryland, uncultivated, wetland), the dataset is converted to a binary classification of irrigated and non-irrigated. 'Irrigated' refers to the detection of any irrigation during the year. The IrrMapper random forest model was trained using an extensive geospatial database of land cover from each of four irrigated- and non-irrigated classes, including over 50,000 human-verified irrigated fields, 38,000 dryland fields, and over 500,000 square kilometers of uncultivated lands.


IrrMapper是使用随机森林算法对美国西部11个州的灌溉状况进行的年度分类(即30米),涵盖1986年至今。虽然IrrMapper论文描述了四个等级的分类(即灌溉、旱地、非耕地、湿地),但数据集被转换为灌溉和非灌溉的二元分类。灌溉的 "指的是在这一年中检测到任何灌溉的情况。IrrMapper随机森林模型是使用一个广泛的地理空间数据库来训练的,该数据库包括来自四个灌溉和非灌溉类别的土地覆盖,包括50,000多块经人类验证的灌溉田,38,000块旱地,以及500,000多平方公里的未开垦土地。
