There’s no open data* for this because churches don’t pay taxes, don’t have business licenses, and aren’t required to register in any way.And Google Maps doesn’t let you have a slice of their database, either.

After you’ve downloaded (via Chrome) or re-saved (Safari) a GeoJSON file of subway data from OpenStreetMap, open QGIS, the free and open source GIS desktop application for Linux, Windows, and Mac.Convert the free and open source data into a shapefile In Safari, a new tab with the GeoJSON text will open (copy and paste this into TextEdit and save it as “mexico_city_subway.geojson”). Screenshot 3: Click the Export button and click GeoJSON. Copy and paste this text into TextEdit and save the file as “mexico_city_subway.geojson”. If you’re using Safari then clicking it will open a new tab and put the GeoJSON text in there. If you’re using Chrome then clicking it will download a file. Now, depending on what browser you’re using, a couple things could happen after you click on GeoJSON. If you’re going to use a desktop GIS software, or place this data in a web map (like Leaflet), then choose GeoJSON. Choose from one of the first three options (GeoJSON, GPX, KML). Download the data by clicking the “Export” button.(You probably don’t want relation if you’re just needing GIS data for mapping purposes, and because routes are not always well-defined by OpenStreetMap contributors.) If you don’t want a particular kind of object, then delete its line from the query and click the “Run” button.Notice that the query has looked for three kinds of objects: node (points/stations), way (the subway tracks), relation (the subway routes). In a few seconds you’ll see lines and dots (representing the metro or subway stations) on the map, and a new query in the text area.(If you want to download interstate highways, or what they call motorways in the UK, use “ highway=motorway“.) Then click the “build and run query” button. In the Wizard dialog box, type in “ railway=subway” in order to find metro, subway, or rapid transit lines.

(Alternatively you can copy the code below and paste it into the text area on the website and click the “Run” button.) Click the “Wizard” button in the top toolbar.
(The Overpass query will be generated in such a way that it’ll only search for data in the current map view.) Open the Overpass Turbo website and, on the map, search for the city from which you want to extract data.Extract free and open source data from OpenStreetMap I’ve also used Overpass Turbo to extract a map of campgrounds. The first extracted places of worship in Cook County. This is my second tutorial to describe using Overpass Turbo.
#Overpass turbo how to
Here’s how to extract the subway lines that are shown in OpenStreetMap and save them as a GIS shapefile. Say you want the subway lines for Mexico City, and you can’t find a GTFS file that you could convert to shapefile, and you can’t find the right files on Sistema de Transporte Colectivo’s website (I didn’t look for it). It’s possible to use Overpass Turbo to extract any object from the OpenStreetMap “planet” and convert it from a GeoJSON or KML file to a shapefile for manipulation and analysis in GIS.
