  1. The main conclusions are following : ( 1 ) compared with the conventional mlc, the method of iterative prior probability based on the vector map can dispel the prior probability ’ s influence and the overall accuracy and kappa index can be improved ; ( 2 ) to the types with greater area than average area of all types, the producer ’ s accuracy will be improved while user ’ s accuracy be lessened, but to the ones with smaller area, the situation is just the opposite

    本研究的主要結論是: ( 1 )與傳統的最大似然法分類相比,利用地理數據矢量化得到的先驗概率進行迭代,可進一步消除先驗概率對最大似然分類法分類結果的影響,使分類總精度和kappa指數有進一步提高; ( 2 )分佈面積大於平均值的類別,生產者精度一般會變高,使用者精度會變低;分佈面積小於平均值的類別,生產者精度一般會變低,使用者精度會變高。
  2. The overall accuracy and kappa index are calculated by using the error matrix to check up the classification ’ s accuracy

    為檢驗分類精度,本文使用了誤差矩陣,計算了分類總精度和kappa指數。
