Let's get started!

1. Download the CSV file below. This is the cleaned data that I'll talk about in the video. The original data source is from NYC Open Data website (feel free to look around that site, but it's not necessary to download anything from that site for this course - just download the CSV below).
2. Open up the "Manhattan_trees_2015.csv" file to make sure you have 4 columns: Status, Health, Latitude, Longitude.

Note: You always need a lat/long before you upload your data to Mapbox so that it knows where to put your points. If you only have the addresses of your points, you can try a website like geocod.io that will find the lat/long for you. Just make sure to carefully check the output - it's not always accurate.

In the next lesson, we'll upload this file to Mapbox.
