摘要
给出常用遥感图像直接统计像点、八链码表示方法计算面积的步骤,并且给出了两种新方法:扫描标号计算面积法和格林公式求面积法.该算法从实际应用出发,较少依赖图像本身的特征,可方便地表示区域并计算出其面积.
It is proposed that remote sensing image element counts directly and eight-direction code calculates the method of area. Two algorithm to calculate the area ; scan grades and Green＇ s formula are put forward. This algorithm can express and calculate the area conveniently and less rely on the native image feature.
