  1. Add GeoJSON content in QGIS: short recipes

    Add simply GeoJSON dataset from QGIS

    Recipe 1: add QGIS built-in data

    You can reuse the QGIS contributors map dataset directly from QGIS without any downloading using PyQGIS. It's a GeoJSON file available within your installed program.

    Just run in QGIS Python console the following

    import os
    from qgis.core import QgsApplication
    geojson_contributors = os.path.join(
    print geojson_contributors
    iface.addVectorLayer(geojson_contributors, 'QGIS contributors', 'ogr')

    Recipe 2: add remote GeoJSON

    This is quite handy to get the remote data. You need to be aware that it's a good solution when remote content change or for demo. However, it's not always a good idea for production where your data can stop being available.

    • Try to do it by going to the website geojson.xyz to get an URL data source.

    The data are coming from Natural Earth Data, the main advantage here is the fact GeoJSON file are delivered via a CDN (Content Delivery Network) whose goal is according to Wikipedia definition

    to serve content to end-users with high availability and high performance

    • Choose a layer source
    • Copy it URL

    Now, you've got an URL to a remote GeoJSON, you can add the GeoJSON from the UI or via PyQGIS.

    From the GUI
