A small package of all GeoJson POJOs (Plain Old Java Objects) for serializing and deserializing of objects via JSON Jackson Parser.
If you know what kind of object you expect from a GeoJson file you can directly read it like this:
FeatureCollection featureCollection = new ObjectMapper().readValue(inputStream, FeatureCollection.class);
If you want to read any GeoJson file read the value as GeoJsonObject and then test for the contents via instanceOf:
GeoJsonObject object = new ObjectMapper().readValue(inputStream, GeoJsonObject.class); if (object instanceof Polygon) { ... } else if (object instanceof Feature) { ... }
and so on.
Or you can use the GeoJsonObjectVisitor to visit the right method:
GeoJsonObject object = new ObjectMapper().readValue(inputStream, GeoJsonObject.class); object.accept(visitor);
Writing Json is even easier. You just have to create the GeoJson objects and pass them to the Jackson ObjectMapper.
FeatureCollection featureCollection = new FeatureCollection(); featureCollection.add(new Feature()); String json= new ObjectMapper().writeValueAsString(featureCollection);
You can find the library in the Maven Central Repository.
