If you have been playing around with the new Mapbox Studio you might be interested to know how to make a custom map with objects of your own interest from OpenStreetMap.

To make the process of creating an updating an OSM based dataset on Mapbox more seamless, I was looking into a command line based workflow that could extract OSM data from Overpass and update a Mapbox hosted dataset in one go.

Requirements

• query-overpass
• mapbox-cli

Generate an Overpass Query

• Use Overpass Turbo to create a query for the data you are interested in extracting. Since i'm interested in bus stops, I first browse the map to Bengaluru, India and then generate a query using the wizard query highway=bus_stop

Anchors in Markdown

To create an anchor to a heading in github flavored markdown. Add - characters between each word in the heading and wrap the value in parens (#some-markdown-heading) so your link should look like so:
