# Simple Features GeoJSON Java
#### Simple Features GeoJSON Lib ####
The Simple Features Libraries were developed at the [National Geospatial-Intelligence Agency (NGA)](http://www.nga.mil/) in collaboration with [BIT Systems](https://www.caci.com/bit-systems/). The government has "unlimited rights" and is releasing this software to increase the impact of government investments by providing developers with the opportunity to take things in new directions. The software use, modification, and distribution rights are stipulated within the [MIT license](http://choosealicense.com/licenses/mit/).

### About ###
[Simple Features GeoJSON](http://ngageoint.github.io/simple-features-geojson-java/) is a Java library for writing and reading [Simple Feature](https://github.com/ngageoint/simple-features-java) Geometries to and from GeoJSON.
### Usage ###
View the latest [Javadoc](http://ngageoint.github.io/simple-features-geojson-java/docs/api/)
#### Read ####
```java
//String content = ...
Geometry geometry = FeatureConverter.toGeometry(content);
mil.nga.sf.Geometry simpleGeometry = geometry.getGeometry();
/* Read as a generic GeoJSON object, Feature, or Feature Collection */
//GeoJsonObject geoJsonObject = FeatureConverter.toGeoJsonObject(content);
//Feature feature = FeatureConverter.toFeature(content);
//FeatureCollection featureCollection = FeatureConverter.toFeatureCollection(content);
```
#### Write ####
```java
//Geometry geometry = ...
String content = FeatureConverter.toStringValue(geometry);
Feature feature = FeatureConverter.toFeature(geometry);
String featureContent = FeatureConverter.toStringValue(feature);
FeatureCollection featureCollection = FeatureConverter.toFeatureCollection(geometry);
String featureCollectionContent = FeatureConverter.toStringValue(featureCollection);
Map contentMap = FeatureConverter.toMap(geometry);
```
