Class Method Details

.convert_to_gpx(opts = {}) ⇒ Object

Conversion can be initiated by either specifying a file, file name, or by passing in GeoJSON data as a string. Examples:

GPX::GeoJSON.convert_to_gpx(geojson_file: 'mygeojsonfile.json')

or

file = File.new('mygeojsonfile.json', 'r')
GPX::GeoJSON.convert_to_gpx(geojson_file: file)

or

data = JSON.generate(my_geojson_hash)
GPX::GeoJSON.convert_to_gpx(geojson_data: data)

Returns a GPX::GPX_File object populated with the converted data.
