I'm trying to find the common borders, which should be as easy as finding the LineString returned from poly1.intersection(poly2).. However, due the the slight inaccuracies I'm finding that intersection is returning Polygon and Point objects, or …

This may be fine for you but will break cases where those vertices are meaningful e.g. openstreetmap road connectivity rules. – Sideshow Bob Sep 20, 2024 at 9:28 Add a comment Your Answer Post Your Answer
Webb1759 coordinate pairs in full data set 178 coordinate pairs in simplified data set 89.9 percent compressed. The Douglas-Peucker algorithm reduced the size of the data set by about 90%, from 1,759 data points in the original full set to 178 points in the new reduced data set. That’s not bad – these stats are comparable to results from ... WebbConcretely, shapely geometry objects are converted into sample points (ndarray). We use args `sample_num`, `sample_dist`, `simplify` to specify sampling method. Args: roi_size (tuple or list): bev range . normalize (bool): whether to normalize points to range (0, 1). coords_dim (int): dimension of point coordinates.
