WebbIf by_feature is TRUE each feature geometry is unioned. This can for instance be used to resolve internal boundaries after polygons were combined using st_combine. If y is provided, all elements of x and y are unioned, pairwise (and by_feature is ignored). The former corresponds to rgeos::gUnaryUnion, the latter to rgeos::gUnion. WebbMMEngine . 深度学习模型训练基础库.
