## KML and KMZ files to Geopackage files
Using a Xml streaming library to read the kml file and convert the hierarchal data into relational data that GeoPackages can store.
### Installation ###
[](https://www.npmjs.com/package/@ngageoint/geopackage-kml-js)
```sh
$ npm install @ngageoint/geopackage-kml-js
```
### Usage
```sh
./cli /path/to/file/to/convert.kml /path/to/file/to/create.gpkg
```
### Javascript
```javascript
const { KMLToGeoPackage } = require('@ngageoint/geopackage-kml-js');
const kmlFile = './test.kml';
const geoPackageFile = './test.gpkg';
const tableName = 'features';
// Convert CSV to GeoPackage feature table
const converter = new KMLToGeoPackage();
converter.convert({ kmlOrKmzPath: kmlFile, geoPackage: geoPackageFile, tableName: tableName }).then(() => {
console.log('File conversion complete');
console.log('Converted %s to %s', kmlFile, geoPackageFile);
});
```

### Currently Supports
- Placemark tags with and without coordinates
Stored as features in a feature table with any additional tags stored in a column of the table.
- Multigeometry tags
- Polygon tags
- inner and outer boundaries.
- LineString tags
- Point tags
- Most of Icon, Polygon and Line Style tags
- color converted to rgba
- GroundOverlay tags
- Image converision from EPSG: 4326 to EPSG: 3857 Web-mercator
- Image manipulation preformed by [Jimp](https://github.com/oliver-moran/jimp).
- Coordinate converision from [Proj4](https://github.com/proj4js/proj4js).
- Creates a tile set at appropriate from the zoomlevels.
- Starting at the zoomlevel where the GroundOverlay is covered by one tile.
- Ending where the image resolution matches that of the tile.
- This is done in steps of 2.
- Default Stylings of Google Earth.
- gx:altitudeMode
- ExtendedData
