GeoJSON is a commonly used and standardized flavor of JSON used for geospatial data. With the introduction of the Point datatype and geospatial functions like convex_hull(...), GeoJSON is a powerful addition that works awesomely with geospatial frameworks like Leaflet.
When GeoJSON is specified as the format, the response will be a standard GeoJSON document compatible with all tools that consume GeoJSON. The Point will be the GeoJSON geometry, and the other fields will be properties. For example:
{
"type": "FeatureCollection",
"features": [
{
"type": "Feature",
"geometry": {
"type": "Point",
"coordinates": [
-87.711722,
41.895615
]
},
"properties": {
"location_state": null,
"location_zip": null,
"x_coordinate": "1153488",
"domestic": false,
"latitude": "41.895614748",
"updated_on": "2015-04-22T12:47:10.000",
"description": "PAROLE VIOLATION",
...
}
}
],
"crs": {
"type": "name",
"properties": {
"name": "urn:ogc:def:crs:OGC:1.3:CRS84"
}
}
}
