Struct GeoJsonFormat 

pub struct GeoJsonFormat {
    pub options: GeoJsonOptions,
}

GeoJSON format handler.

This format handler can import and export narratives in GeoJSON format, storing events as Features with Point geometries. Temporal and metadata information is stored in feature properties.

Example

use spatial_narrative::io::{GeoJsonFormat, Format};
use spatial_narrative::prelude::*;

let format = GeoJsonFormat::default();

// Import from GeoJSON
let geojson = r#"{
  "type": "FeatureCollection",
  "features": [
    {
      "type": "Feature",
      "geometry": {
        "type": "Point",
        "coordinates": [-74.006, 40.7128]
      },
      "properties": {
        "text": "Something happened",
        "timestamp": "2024-01-15T14:30:00Z"
      }
    }
  ]
}"#;

let narrative = format.import_str(geojson).unwrap();
assert_eq!(narrative.events().len(), 1);
