PointAnnotation

PointAnnotation

• PointAnnotation represents a one-dimensional shape located at a single geographical coordinate.
  
  Consider using ShapeSource and SymbolLayer instead, if you have many points and you have static images,
  they'll offer much better performance
  
  .
  If you need interctive views please use MarkerView,
  as with PointAnnotation on Android child views are rendered onto a bitmap for better performance.
