How to load ArcGIS JSON data into mapbox?

vgoklani commented 5 years ago

I've downloaded some ArcGIS JSON but I'm unable to import it into Mapbox.

This is a sample of the geodata (I've trimmed the JSON object):

{'displayFieldName': 'NAME',
 'fieldAliases': {},
 'geometryType': 'esriGeometryPolygon',
 'spatialReference': {'wkid': 102100, 'latestWkid': 3857},
 'fields': [],
 'features': [{'attributes': {'OBJECTID': 2050,
    'PRECINCTID': '01029B',
    'NAME': 'COLUMBUS 29-B',
    'COUNTY': None,
    'ESS_PRECINCT_NO': None,
    'ESS_PRECINCT': None,
    'CITY_OR_VILLAGE': None,
    'SCHOOL_DISTRICT': None,
    'TOWNSHIP': None,
    'HOUSE_DISTRICT': None,
    'SENATE_DISTRICT': None,
    'CONGRESS_DISTRICT': None,
    'POLICE_DISTRICT': None,
    'ROAD_DISTRICT': None,
    'FIRE_DISTRICT': None,
    'PARK_DISTRICT': None,
    'COURT_APPEALS_NAME': None,
    'BOARD_OF_ED_NAME': None,
    'LIBRARY': None,
    'EDUCATIONAL_SERVICE_CENTERS': None,
    'CAREER_CENTERS': None,
    'WINNINGPARTY': None,
    'TOTALBALLOTS': None,
    'SHAPE_Length': 26636.15475759097,
    'SHAPE_Area': 30443700.474467456,
    'POLLINGID': None,
    'POLLINGLOCATION': None,
    'LID': 'N/A',
    'Symbol': 'A'},
   'geometry': {'rings': [[[-9235687, 4854329],
      [-9235918, 4851467],
      [-9239010, 4854564],
      [-9235687, 4854329]]]}},
]}

How do I render this data in Mapbox? I've seen the instructions for loading geojson, but not ArcGIS JSON. Thanks!

Hmm, I've only worked with GeoJSON similar to the examples in the spec at https://geojson.org/. Looks like ESRI might have a particular structure we'll need a converter for. You'll also have to account for projection, since it looks like your data is in map coordinates rather than latitude/longitude.

I converted this data into geojson, but was unable to render it in Mapbox. I posted this under a separate question here - please let me know if it makes sense.

@vgoklani to test if you have valid geoJSON, try exporting your data to file and loading it in a tool like www.geojson.io

mapbox / mapboxgl-jupyter
