Usage

  • Create a Point
val point = Point(latitude = 1.0, longitude = 2.0)
  • Incorporate point into a Feature
val feature = Feature(geometry = point)
  • Then incorporate feature into a FeatureCollection
val featureCollection = FeatureCollection(1, listOf(feature))
  • For each GeoJson object, you can call toJson()
val geoJsonText = featureCollection.toJson()
  • Parsing :
val geoJsonObjectOut: FeatureCollection = FeatureCollection.fromJson(geoJsonText)

GsonBuilder

To serialize and parse GeoJson you need to register special adapter to GSon

val gson = GsonBuilder()
            // registering KGeoGson adapter here
            .registerGeoJsonTypeAdapters()
            .create()
