Webb29 apr. 2014 · Shapely finds the intersection point of the bowtie, but only keeps the top-right portion. Looking for a workaround, I tried reversing the order of my points. Surprisingly (to me), the same top-right portion of the bowtie was still the one kept. I don't understand. Any help appreciated. 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 ...

Webb13 juni 2024 · 1 Answer Sorted by: 4 As mentioned, you need a topology aware simplification algorithm. For this I use the topojson package: gdf = import topojson as tp topo = tp.Topology (gdf.to_crs ( {'init':'epsg:3857'}), prequantize=False) simple = topo.toposimplify (1).to_gdf () # optional simple.plot () … WebbHow to use the shapely.geometry.box function in shapely To help you get started, we’ve selected a few shapely examples, based on popular ways it is used in public projects.

python - Simplify line string considering angles - Stack Overflow
Webb16 maj 2024 · You can use the simplify method to achieve that: new_line = line.simplify(tolerance=MIN_DISTANCE) with your example it would be: from shapely.geometry import LineString, Point xs = range(10) ys = range(10) x, y = zip(*[(1, 1), (1.1, 1.1), (3, 3)]) points = [Point(x, y) for x, y in zip(x, y)] ... 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. WebbI have some fairly complex, and not completely accurate shapes stored as shapely Polygon objects. 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 … reagan white
