Data Visualization with Python Folium Maps

Sign in to your account. I would like to play with the available icon in folium. Is there a list somewhere so I can output with your icon before customizing? Not sure what you mean there. Can you clarify what if that you want to do? Also, take a look at the custom icons example and the many builtin options. Take a look at the docs with help folium. I believe you'll find what you want.

I keep finding this result in my Google searches for list of icons and always ending running help folium. Icon to find the following urls:. Skip to content.

I am using folium to create a choropleth map of a set of countries. I am following the documentation. I am using the world geojson from natural earth see the gist.

However, am not getting any choropleth result and left with just the base country map as below. I figured out the problem. To plot the choropleth I needed to keep only those keys in the geojson which were also in my data frame.

Will update the gist tonight. Great, thanks : Looking forward to seeing your code! Active Oldest Votes.You can see this Domino project here. I get very excited about a nice map. But when it comes to creating maps in Python, I have struggled to find the right library in the ever changing jungle of Python libraries.

After some research I discovered Foliumwhich makes it easy to create Leaflet maps in Python. This blog post outlines how I used Folium to visualize a data set about crime in San Francisco.

I then describe a how to use Domino to turn this Python code into a self-service reporting tool. Folium is a powerful Python library that helps you create several types of Leaflet maps.

The fact that the Folium results are interactive makes this library very useful for dashboard building. The Folium github contains many other examples. In case you use Jupyter like myselfyou might prefer to get inline maps.

This Jupyter example shows how to display maps inline. For this example I needed some interesting data that contains locations.

Use the Export function select csv to download the entire dataset. The Jupyter notebook contains only a few lines of code.

It loads the incident file into a pandas dataframe, selects the first records to speed things up a little, and creates an inline map containing an interactive map with markers based on the resulting dataset. The tileset used in here is OpenStreetMap which is default. Folium can be used with other tilesets like Mapbox or Cloudmade too. You save a map as an html file by using map. Well, that was fun!

But this might not be an ideal visualization to compare maps with each other.

Lucky for us, there is also a way to create a choropleth map thanks to Folium. The next step is to convert the Shapefile into a geojson file. The easiest way is to use an ogr2ogr web client. Select the downloaded zip file and put crs in the Target SRS field. Save the result as sfpddistricts.

The additional Python code to create a choropleth is as follows. Note that I used the whole dataset instead of the records used earlier. It creates a choropleth map like below with a legend in the upper right corner. The aggregated counts are stored in a separate json file crimedata2. The crime incident data is much richer than just locations and districts. It also contains variables like categories, dates and times. This creates the opportunity to, for instance, get better insights in specific sorts of incidents.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

I am playing with Folium a lot right now and its really great to have something so easy to use in Python. But their documentation is seriously behind, which I understand. So I have 2 questions. They should all make the marker yellow, instead it stays default red. The only colors I can actually change to are red, green, and purple.

In an example from the folium documentation it looks like we should be able to use html color codes:. But it doesn't work for me. Hope someone knows a way around this because I need at least 12 different colors for my project.

Leaflet is a popular JavaScript library for creating interactive maps for webpages OpenLayers is another JavaScript library for the same purpose.

Here, will focus on two Python libraries - mplleaflet and Folium - that are able to convert our data in geo pandas into interactive Leaflet maps. We can also convert maptlotlib plots directly to interactive web maps using mllpleaflet.

We can also render the map insite the notebook following this example :. Folium is a Python library that makes it possible visualize data on an interactive Leaflet map. We just visualize OpenStreetMap on a specific location of the a world. First thing that we need to do is to create a Map instance.

The first parameter location takes a pair of lat, lon values as list as an input which will determine where the map will be positioned when user opens up the map. Navigate to the location where you saved the html file and open it in a web browser preferably Google Chrome.

Open the file also in a text editor to see the source script. Create another map with different settings location, bacground map, zoom levels etc. See documentation of class folium.

Map for all avaiable options. As mentioned, Folium combines the strenghts of data manipulation in Python with the mapping capabilities of Leaflet.

Now we have our population data stored as GeoJSON format which basically contains the data as text in a similar way that it would be written in the. We can also add a LayerControl object on our map, which allows the user to control which map layers are visible. See the documentation for available parameters you can e. Folium plugins allow us to use popular plugins available in leaflet. One of these plugins is HeatMapwhich creates a heatmap layer from input points.

HeatMap requires a list of points, or a numpy array as input, so we need to first manipulate the data a bit:. This method is able to read the geometries and attributes directly from a geodataframe.

This example is modified from the Folium quicksart.

This example comes directly from the awesome documentation of this library. Note that you need 2 elements to build a chloropleth map.

You can file the 2 files used to build this example here. Pingback: Part 3 — numbers. When executing the same code with the same values in jupyter notebook there is no color appears in the map all of the sates are dark grey what could be the possible reason?
