MultiPoint.parse constructor

MultiPoint.parse(String text, { TextReaderFormat<SimpleGeometryContent> format = GeoJSON.geometry, CoordRefSys? crs, Map<String, dynamic>? options, })

Parses a multi point geometry from text conforming to format.

When format is not given, then the geometry format of GeoJSON is used as a default.

Use crs to give hints (like axis order, and whether x and y must be swapped when read in) about coordinate reference system in text input. When data itself have CRS information it overrides this value.

Format or decoder implementation specific options can be set by options.

Examples:

// a multi point from three 2D positions
MultiPoint.parse(
  format: GeoJSON.geometry,
  '''
  {
    "type": "MultiPoint",
    "coordinates": [[10.0,20.0],[12.5,22.5],[15.0,25.0]]
  }
  ''',
);
MultiPoint.parse(
  format: WKT.geometry,
  'MULTIPOINT ((10.0 20.0),(12.5 22.5),(15.0 25.0))',
);

// a multi point from three 3D positions
MultiPoint.parse(
  format: GeoJSON.geometry,
  '''
  {
    "type": "MultiPoint",
    "coordinates": [[10.0,20.0,30.0],[12.5,22.5,32.5],[15.0,25.0,35.0]]
  }
  ''',
);
MultiPoint.parse(
  format: WKT.geometry,
  'MULTIPOINT Z ((10.0 20.0 30.0),(12.5 22.5 32.5),(15.0 25.0 35.0))',
);

Implementation

factory MultiPoint.parse(
  String text, {
  TextReaderFormat<SimpleGeometryContent> format = GeoJSON.geometry,
  CoordRefSys? crs,
  Map<String, dynamic>? options,
}) =>
    GeometryBuilder.parse<MultiPoint>(
      text,
      format: format,
      crs: crs,
      options: options,
    );
