folium

问题 I have used GeoJson method in FeatureGroup of folium to add polygon layers to my map. I am getting some error. I have checked the syntax of this method.Everything is correct but still i am getting the error mentioned below in the image. 回答1: I stumbled upon the same issue. From the documentation at https://python-visualization.github.io/folium/modules.html#folium.features.GeoJson you can see various examples of opening the geojson file. >>> # Providing file that shall be embedded. >>> GeoJson

问题 I'm interested in creating Choropleth map with Python on a county level. When I run my code without trying to bind data to it I get the county lines drawn in beautifully. However whenever I try to bind my data I get KeyError: None. From my searching it appeared as though this is due to values in the GeoJson not matching up with the values in the data file... but I went in manually and checked and have already edited the data so there are the exact same number of rows and exact same values...

问题 I am using folium to visualise zones in an city. My GeoJSON is a FeatureCollection with multiple polygons as features. I want to be able to add different popups for different polygons in the file. The idea is to show names of the different polygons in the GEOJSON file. I was able to add a popup to the complete geoJSON. However, I want to be able to add different popup for different polygons (essentially the name of the feature). folium.GeoJson(gurgaon_subzone,name='geojson').add_child(folium

问题 I have successfully rendered folium maps on my jupyter notebook by increasing the data limit when launching jupyter from anaconda prompt like this: "jupyter notebook --NotebookApp.iopub_data_rate_limit=1.0e10" However, when I have uploaded the notebook to Github, rather than the map I had processed, I got a blank window. How can I render these maps? Is it possible to increase the data_rate_limit on the notebook when it is being launched through github? 来源： https://stackoverflow.com/questions

问题 This question already has answers here : How to serve static files in Flask (16 answers) Closed 3 years ago . So I am using this cool plugin called Folium which creates maps. The map gets created as a .html and every time you update the map it regenerates the html. So in order to display the map and my navbar and other stuff on the same page I think I would need to put map.html inside an iframe cage where it can refresh itself at will. The map gets created thus: map1 = folium.Map(location=[45

问题 I'm working on producing a series of maps for an animated presentation using Folium and my code (when plotting over 100 circles) always ends in a blank map. If I decrease the number of circles to 100 or below, it works perfectly. Is this a folium limitation or something I can change on my local machine with Java or Browser settings? I'm using python in jupyter notebook in chrome on Ubuntu. merged_hourly is a pandas df with nyc foottraffic data for specific stations, lat, long, etc. Exported

问题 Very new to Django (and web development in general), so apologies in advance. I'm trying to display my Folium map in a Django webpage, but I can't seem to figure out why I end up getting a blank screen. I looked for other posts in SO, but they're all asking for either the pop-ups specifically or displaying in Jupyter. views.py from django.shortcuts import render, redirect, render_to_response from django.http import HttpResponse from django.template.loader import get_template from django

问题 Is there any list of icons available that I can use in a expression like I use home in this one? folium.Marker(location=[0,20], icon=folium.Icon(color='lightgray', icon='home', prefix='fa')).add_to(m) 回答1: You can find a full list here: https://fontawesome.com/icons?d=gallery use with: prefix='fa' or the glyphicon icons of Bootstrap that are built-in and standard, thus without prefix needed. https://getbootstrap.com/docs/3.3/components/ 来源： https://stackoverflow.com/questions/53721079/python

问题 The Folium documentation is incomplete at this time: https://folium.readthedocs.io/en/latest/ According to the index of the incomplete docs Legends and Layers are, or will be supported. I've spent some time looking for examples on the web but have found nothing so far. If anyone has any idea how to create these things, or can point me to a document or tutorial I would be most grateful. 回答1: You can add a legend quite easily; #specify the min and max values of your data colormap = branca

问题 My problem is that suburbs are not displaying the correct color on the Folium map. For example, Dandenong and Frankston should be shaded with the darkest color as they have the highest count in the dataframe, but they are shaded with a lighter color. The dataframe is missing some suburbs. Those suburbs are being colored with the darkest color. Another problem is the csv has all suburbs in UPPERCASE but the geojson has a mixture of cases such as "Frankston", "St Kilda", or "McKinnon". It would
