The purpose of using a color filled map like the one above is usually to have the color represent something in the data, e. Next, display an OpenStreetMap and overlay the cantons of Switzerland on top from the geojson file created earlier. You should now see an map of Switzerland with surrounding countries and cities. I use the simplify option to reduce the file size, at the expense of accuracy. You now have a map in your local directory, formatted as a geojson file. A sample geojson file has been supplied with this tutorial, but for reference you can create a geojson file from the shape files from a console like this.
Since we will be working with geojson files in this demonstration you need to convert them to geojson. In this case what we have are a set of shapefiles. There are many file formats commonly used for maps. We have provided the shape files we will use for this demonstration, normally you would need to retrieve and unpack the map data. However, you might want use concepts such as regions, and you need to define them through files containing those geolocations. The maps are automatically pulled from OpenStreetMap. Using the method described here, you do not need any local map data. It is the Swiss National Day after all! During this renovation, I stumbled upon GeoPandas, which is a great package worth mentioning in this context. MarjorieRoswell, can you tell whether the source data was the issue, or is there a problem with only the JSON? Here's what CA should look like for the current congress: nationalatlas.August 1, This post is almost a year old, but I decided to make some technical improvements to it to improve the viewing experience online. Was using these, gratefully, but just noticed that California districts are not accurate for th Congress. Not much US data but I was super happy to find geojson.Īctive Oldest Votes. I was just curious if there was a more comprehensive source for US data. Casey Casey 2, 1 1 gold badge 14 14 silver badges 23 23 bronze badges.

Feel free to use these if they will help. Country boundaries for the whole world are available in this repo too.
We then aggregate by the count to find the total times each facility has violated a particular rule.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. We begin this by grouping the violation dataframe by the facility id and the violation code. For extracting the size of the establishment, I used the regex? Individual violations do not seem to tell us much about a particular location. To better represent the data, we write three helper functions with regex and string split to create new feature variables.Ī quick description of the two regex statements used here.įor extracting the type of establishment, we want to get everything before the first opening parentheses.
It seems to describe 3 different things: what type of establishment it is, how many people it can host, and the risk level. When matched with the violation description, they were the only descriptions that did not have a violation number in front of them.Īs they only make up 17 entries out of theviolations, we can safely drop them. For the purposes of this analyses, we only keep the first 5 digits. These digits are mainly for USPS mail sorting. A look at unique zip codes found many with additional 4 digits appended to the usual 5 digits. Lets start with loading the csv files into data frames and seeing what variables we have. There are two separate csv files available: one for inspection records and one for violation records. We look at the LA county restaurant and market inspection dataset for this purpose. Datasets with geographical data such as latitudes, longitudes, and FIPS codes lend themselves really well to visualization through mapping packages like Folium.
