GeoJsonDataSource

new GeoJsonDataSource(name)

A DataSource which processes both GeoJSON and TopoJSON data. Simplestyle properties will also be used if they are present.
Name Type Description
name String optional The name of this data source. If undefined, a name will be taken from the name of the GeoJSON file.
Example:
var viewer = new Cesium.Viewer('cesiumContainer');
viewer.dataSources.add(Cesium.GeoJsonDataSource.fromUrl('../../SampleData/ne_10m_us_states.topojson', {
  stroke: Cesium.Color.HOTPINK,
  fill: Cesium.Color.PINK,
  strokeWidth: 3,
  markerSymbol: '?'

Members

staticGeoJsonDataSource.crsLinkHrefs :Object

Gets an object that maps the href property of a crs link to a callback function which takes the crs properties object and returns a Promise that resolves to a function that takes a GeoJSON coordinate and transforms it into a WGS84 Earth-fixed Cartesian. Items in this object take precedence over those defined in crsLinkHrefs, assuming the link has a type specified.
Source: DataSources/GeoJsonDataSource.js, line 628

staticGeoJsonDataSource.crsLinkTypes :Object

Gets an object that maps the type property of a crs link to a callback function which takes the crs properties object and returns a Promise that resolves to a function that takes a GeoJSON coordinate and transforms it into a WGS84 Earth-fixed Cartesian. Items in crsLinkHrefs take precedence over this object.
Source: DataSources/GeoJsonDataSource.js, line 642

staticGeoJsonDataSource.crsNames :Object

Gets an object that maps the name of a crs to a callback function which takes a GeoJSON coordinate and transforms it into a WGS84 Earth-fixed Cartesian. Older versions of GeoJSON which supported the EPSG type can be added to this list as well, by specifying the complete EPSG name, for example 'EPSG:4326'.
