folium

问题 I'm trying to do a choropleth using folium which offers a great link between GeoJSON, Pandas and leaflet. GeoJSON format is like below : { "type":"FeatureCollection", "features":[ { "type":"Feature", "geometry": { "type":"Polygon", "coordinates":[[[-1.6704591323124895,49.62681486270549], ..... { "insee":"50173", "nom":"Équeurdreville-Hainneville", "wikipedia":"fr:Équeurdreville-Hainneville", "surf_m2":12940306}}, Pandas DataFrame : postal_count.head(5) Out[98]: Code_commune_INSEE CP_count 0

问题 I have two choropleth layers in which I would like to add GeoJsonTooltip to but I keep receiving error TypeError: __init__() missing 1 required positional argument: 'text' My current code is as follows. import folium import pandas as pd import json df_theft = pd.read_csv('PA_Theft.csv') df_assualt = pd.read_csv('PA_Assualt.csv') theft_json = json.load(open('theft_geojson.json')) assualt_json = json.load(open('assualt_geojson.json')) m = folium.Map(location=[41.20, -77.50], tiles="cartodbdark

问题 I want a map of Europe (as json file, so i can work with geojson) to place it on Folium map as layers so I am able to embed my data set onto it to show which country in Europe has the highest alcohol serving. I am having problems with getting the json file from GitHub to open in jyputer This is what I have so far and i have the file of europe country in geojson from github https://github.com/Leaflet/Leaflet.VectorGrid/blob/master/docs/eu-countries.geo.json 回答1: You will have to download that

问题 i want to display some geo locations on map, but i want the map-pin icon to display numbers instead of the default map pin. Is there any way to do that? I checked in font awesome icons but it didn't work. Below is my code: import folium m = folium.Map( location=[45.3288, -121.6625], zoom_start=12, #tiles='Mapbox Bright' ) folium.Marker([45.3288, -121.6625], popup='<i>Mt. Hood Meadows</i>').add_to(m) folium.Marker([45.3311, -121.7113], popup='<b>Timberline Lodge</b>',icon=folium.Icon(color=

问题 I have 3 main values (longitude, latitude and speed) in csv. Using Folium library i can map the location with lon and lat degree.my current code is: import pandas as pd from geopy.geocoders import Nominatim import folium from pandas import * import numpy as np from matplotlib import cm import folium df = DataFrame({'lon': [9.899193, 9.899236, 9.899292, 9.899331, 9.899372, 9.899411, 9.89946, 9.899518, 9.899393, 9.899409, 9.899456, 9.899498, 9.89952, 9.899558, 9.8996, 9.899625, 9.899646, 9

问题 I have this sample code: from glob import glob import numpy as np import folium from folium import plugins from folium.plugins import HeatMap lon, lat = -86.276, 30.935 zoom_start = 5 data = ( np.random.normal(size=(100, 3)) * np.array([[1, 1, 1]]) + np.array([[48, 5, 1]]) ).tolist() m = folium.Map([48, 5], tiles='stamentoner', zoom_start=6) HeatMap(data).add_to(m) m How can I add this heat map to a layer so I can hide it if needed? 回答1: I would first add your HeatMap to a FeatureGroup and

问题 I try to add an image to folium popup, but failed. I use python 2.7 version, and folium 0.50 version. Actually, I follow the page mention in other threads, but it still doesn't work http://nbviewer.jupyter.org/gist/ocefpaf/0ec5c93138744e5072847822818b4362 import folium import base64 m = folium.Map(location = [33, -97], zoom_start = 6, tiles = "Mapbox Bright") encoded = base64.b64encode(open('IMG_1769.JPG', 'rb').read()).decode() html = '<img src="data:image/jpeg;base64,{}">'.format iframe =

问题 I am trying to import folium into a Jupyter notebook I'm working on and I cannot seem to solve the import issues with the Folium library. Has anyone else solved this problem? !pip install folium import pandas as pd import folium Output from the above yields: `ModuleNotFoundError Traceback (most recent call last) <ipython-input-7-a9938c267a0c> in <module>() 1 get_ipython().system('pip install folium') 2 import pandas as pd ----> 3 import folium ModuleNotFoundError: No module named 'folium'`

问题 I am trying to create a choropleth map using folium, following the example here: https://pypi.python.org/pypi/folium. The goal is to produce a choropleth map of US unemployment rates, but when I open my map US states are not shaded in. Any suggestions? import folium import pandas as pd state_geo = r'data/us-states.json' state_unemployment = r'data/US_Unemployment_Oct2012.csv' state_data = pd.read_csv(state_unemployment) #Let Folium determine the scale map = folium.Map(location=[48, -102],

问题 I am trying to use Folium for geographical information reading from a pandas dataframe. The code I have is this one: import folium from folium import plugins import pandas as pd ...operations on dataframe df... map_1 = folium.Map(location=[51.5073219, -0.1276474], zoom_start=12, tiles='Stamen Terrain') markerCluster = folium.plugins.MarkerCluster().add_to(map_1) lat=0. lon=0. for index,row in df.iterrows(): lat=row['lat] lon=row['lon'] folium.Marker([lat, lon], popup=row['name']).add_to
