Usage

Command Line

./cli /path/to/file/to/convert.json /path/to/file/to/create.gpkg

Javascript

const { GeoJSONToGeoPackage } = require('@ngageoint/geopackage-geojson-js');
const geoJSONFile = './test.json';
const geoPackageFile = './test.gpkg';
const tableName = 'features';

// Convert GeoJSON to GeoPackage feature table
const converter = new GeoJSONToGeoPackage();
converter.convert({ geoJson: geoJSONFile, geoPackage: geoPackageFile, tableName: tableName }).then(() => {
  console.log('File conversion complete');
  console.log('Converted %s to %s', geoJSONFile, geoPackageFile);
