我如何丢下面包屑”沿着每米的边缘每米以在OSMNX中创建节点之间？

OSMNX 中是否有一种方法可以沿着投影图的每条边每 N 米添加中间节点？

我认为这在某种程度上与简化相反。

如果道路上有很长的弯道，节点仍然应该添加在弯道上，而不是像乌鸦飞一样。

import osmnx as ox

G = ox.graph_from_place('Cortlandt, New York', network_type='drive', simplify=True)

Gp = ox.project_graph(G)

nodes, edges = ox.graph_to_gdfs(Gp)

# nodes is a GeoDataFrame with GeoSeries of "osmid", "y", "x", "lat", "lon", "highway", and "geometry"

# this is awkward to reference

ls = edges["geometry"][191122010][3046769062]
length_m = edges["length"][191122010][3046769062][0]

d_m = 0

while d_m < length_m:
  point = ls.interpolate(d_m)

  node = ...       # TODO

  G.add_node(node)

  d_m += 50

因此，问题是我如何创建一个与边缘上的其他节点具有相同属性但不使用 LineString 而是使用点的节点？我如何从插值点获得经纬度？

Is there a way in OSMNX to add inbetween nodes along each edge of a projected graph every N meters?

This is I suppose the opposite of simplification in a way.

If there's a long curve on a road, the nodes should still be added on the curve not as the crow flies.

import osmnx as ox

G = ox.graph_from_place('Cortlandt, New York', network_type='drive', simplify=True)

Gp = ox.project_graph(G)

nodes, edges = ox.graph_to_gdfs(Gp)

# nodes is a GeoDataFrame with GeoSeries of "osmid", "y", "x", "lat", "lon", "highway", and "geometry"

# this is awkward to reference

ls = edges["geometry"][191122010][3046769062]
length_m = edges["length"][191122010][3046769062][0]

d_m = 0

while d_m < length_m:
  point = ls.interpolate(d_m)

  node = ...       # TODO

  G.add_node(node)

  d_m += 50

The question is thus how I do create a node that has the same attributes as other nodes on the edge but doesn't use a LineString but rather a point? And how would I get a lat, lon from the interpolated point?
