# Simple Features Projection Java
#### Simple Features Projection 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/).
### Pull Requests ###
If you'd like to contribute to this project, please make a pull request. We'll review the pull request and discuss the changes. All pull request contributions to this project will be released under the MIT license.

### About ###
[Simple Features Projection](http://ngageoint.github.io/simple-features-proj-java/) is a Java library for performing projection conversions between [Simple Feature](https://github.com/ngageoint/simple-features-java) Geometries.
### Usage ###
View the latest [Javadoc](http://ngageoint.github.io/simple-features-proj-java/docs/api/)
#### Transform ####
```java
//Geometry geometry = ...
Projection projection1 = ProjectionFactory.getProjection(
ProjectionConstants.AUTHORITY_EPSG,
ProjectionConstants.EPSG_WEB_MERCATOR);
Projection projection2 = ProjectionFactory.getProjection(
ProjectionConstants.AUTHORITY_EPSG,
ProjectionConstants.EPSG_WORLD_GEODETIC_SYSTEM);
GeometryTransform transform = GeometryTransform.create(projection1,
projection2);
Geometry transformed = transform.transform(geometry);
```
