Web一、前言. 面向对象分类其实在学界统称基于对象的图像分析(OBIA),而在遥感等地学细分领域中,其称为基于地理对象的图像分析(GEOBIA),这种算法优势非常明显。. 与普通的像元暴力迭代分类不同,对象的概念体现在同质像元的集合,这样能够很大程度 ... WebJul 31, 2024 · It looks exactly the same in the Data Inspector, but the numbers are slightly different. I figure the two results are just on a different scale. I’m going with the RasterSlopeCalculator as the definitive answer because it tells me what the number means (percentage slope) whereas I’m unsure if the convolved numbers actually represent ...
