## Introduction

This Java library can convert JTS geometries to GeoJSON and back. Its API is similar to other io.* classes in JTS.

[![Build Status](https://github.com/bjornharrtell/jts2geojson/actions/workflows/maven.yml/badge.svg)](https://github.com/bjornharrtell/jts2geojson/actions/workflows/maven.yml)

## Maven

```xml
<dependency>
    <groupId>org.wololo</groupId>
    <artifactId>jts2geojson</artifactId>
    <version>0.18.1</version>
</dependency>
```

## Usage

```java
  GeoJSONWriter writer = new GeoJSONWriter();
  GeoJSON json = writer.write(geometry);
  String jsonstring = json.toString();

  GeoJSONReader reader = new GeoJSONReader();
  Geometry geometry = reader.read(json);
```

## Features and FeatureCollections

JTS does not have anything like GeoJSON Feature or FeatureCollection but they can be parsed by this library. Example:

```java
  // parse Feature or FeatureCollection
  Feature feature = (Feature) GeoJSONFactory.create(json);
  FeatureCollection featureCollection = (FeatureCollection) GeoJSONFactory.create(json);

  // parse Geometry from Feature
  GeoJSONReader reader = new GeoJSONReader();
  Geometry geometry = reader.read(feature.getGeometry());
  geometry = reader.read(featureCollection.getFeatures()[0].getGeometry());

  // create and serialize a FeatureCollection
  List<Features> features = new ArrayList<Features>();
  Map<String, Object> properties = new HashMap<String, Object>();
  features.add(new Feature(geometry, properties));
  GeoJSONWriter writer = new GeoJSONWriter();
  GeoJSON json = writer.write(features);
```
