问题 I have this code based on this question, just a different point Extract constrained polygon using OSMnx I am trying to plot the block in which the point is located but it does nothing, it just prints "Done" but I cannot see any image import osmnx as ox import geopandas as gpd import shapely point = (50.090464, 14.400070) streets_graph = ox.graph_from_point(point, distance=500, network_type='drive') streets_graph = ox.project_graph(streets_graph) streets = ox.save_load.graph_to_gdfs(streets

问题 I have used a fresh anaconda install to download and install all the required modules for osnmx library but I got the following error: 回答1: I have had the same issue and turned out that it did not like the latest release of osmnx (0.11.3). It could be that that version is unstable as its new (9th January 2020). I have sort out the issue by uninstalling the osmnx 0.11.3 conda uninstall osmnx and forcing to install the osmnx 0.11 version pip install osmnx==0.11 来源： https://stackoverflow.com

问题 I am wondering if it is possible to plot area objects from OSM through OSMnx. It seems to me, that there is an easy way only to plot buildings. But I would like to be able to plot e.g. rivers, but can't find a place to specify this. I was hoping for a similar mechanism to plotting different way objects (e.g. power lines) through infrastructure parameter in graph_from_bbox function. Is there something like that but for areas? What I did already is to try a minimal example: import osmnx as ox

问题 I'm using the wonderful OSMnx library created by Geoff Boeing. I am plotting a street network based on one of his tutorials. Everything works perfectly. However, I would like to plot more than 40 graphs, using different centralities. Therefore, I would like to add a title with each district and centrality name to each plot. Currently, it looks like this. Plotted OSMnx Street Network This is what my code looks like. def display_most_important_node(G_centralities_sorted_dict, G_dictionary,

问题 I'm trying to plot the graph of edge centrality on the folium using the following code graph_map = ox.plot_graph_folium(G, popup_attribute='name', tiles='stamenterrain', edge_color=ec, edge_width=2) where ec is list of edge colors but it is not showing up. Does edge_color accept a list of colors ? Any ideas? I really appreciate if you can help me. https://github.com/gboeing/osmnx-examples/blob/master/notebooks/08-example-line-graph.ipynb 回答1: I tried adding a new column of edge color to gdf

问题 I know it is possible to extract the road network of a city via the OSMNX python package. See details at https://geoffboeing.com/2016/11/osmnx-python-street-networks/ . paris_network = ox.gdf_from_place("Paris") But, let's say I do not want that level of high details, but rather only big freeways of a whole country. I'm looking for something like : france_big_expressway_network = ox.gdf_from_place("France", road_type = "freeway") I guess it might comes from the "infrastructure" argument but

问题 With OSMnx, I would like to be able to save a path with its curvature as the image below shows. import osmnx as ox import networkx as nx # Download the road network G = ox.graph_from_place('Monterey, California', network_type='drive') # Starting and ending point of a trip start = [36.580665,-121.8297467] end = [36.594319,-121.8727587] # Retrieve nearest node orig_node = ox.get_nearest_node(G, start) dest_node = ox.get_nearest_node(G, end) # Compute the path of the trip route = nx.shortest
