openstreetmap

问题 I am using QML on Qt to display OpenStreetMap (using the osm plugin), which requires internet connection. Is there a way that I can do the same but running it offline? For example, running my own tile server (but how easy is that to do)? Or using a library that will let me do it quite quickly. By the way I am running my program on Ubuntu. Any help on how to do that and especially if someone can provide the steps to be done would be appreciated. Thank you. 回答1: I have managed to display

问题 I am using OSMnx to get clean intersections from OpenStreetMaps road network. The intersection nodes are currently in (x,y) coordinates, but I want to plot them using lat lon coordinates. From the example Jupiter notebook, OSMnx Example #14 Clean Intersection Cluster Nodes, I am able to get the street network and call ox.clean_intersections to produce the clean intersections. import osmnx as ox, matplotlib.pyplot as plt, numpy as np ox.config(use_cache=True, log_console=True) %matplotlib

问题 I'm pretty new to PHP and the whole thing of working with RESTful APIs. All I want to do at the moment is successfully issue a plain HTTP GET request to the OpenStreetMap API. I am using the simple PHP REST client by tcdent and I basically understand it's functionality. My example code for getting the current Changesets in OSM is: <?php include("restclient.php"); $api = new RestClient(array( 'base_url' => "http://api.openstreetmaps.org/", 'format' => "xml") ); $result = $api->get("api/0.6

问题 import osmnx as ox ox.__version__ # '0.13.0' I would like to show the bus routes from the Open Street Map for Hannover on a map using OSMNX by retrieving them as ". graph... ". E.g.: G = ox.graph_from_place('Hannover, Germany', retain_all=False, truncate_by_edge=True, simplify=True, network_type=None, custom_filter='["route"~"bus"]') # returns EmptyOverpassResponse: There are no data elements in the response JSON But I guess this only works for OSM Nodes and Ways, not for Relations?

问题 I am trying to run the osmar package on my windows 10, R 3.4.2, and have correctly installed osmosis.
