Plant community maps were produced from aerial photointerpretation of 1-foot resolution, 4-band orthoimagery flown February 19, 2015. Plant communities were heads-up digitized in ESRI ArcMap with a 0.5 acre minimum mapping unit. Map accuracy assessment was 96% calculated as the overall probability correct using map marginal proportions.本数据集的植物群落图基于2015年2月19日获取的1英尺分辨率、4波段正射影像（4-band orthoimagery）的航空像片解译（aerial photointerpretation）制作而成。植物群落要素在ESRI ArcMap（ESRI ArcMap）中通过平视数字化方式进行矢量化，最小制图单元（minimum mapping unit）为0.5英亩。本次地图精度评估采用地图边际比例（map marginal proportions）计算总体正确概率（overall probability correct），最终得到的总体分类准确率为96%。
