Writer Parameters
Output Character Set
The character set encoding in which the GeoJSON text will be written. If no character set is specified, the GeoJSON text will be written in the UTF-8 character set.
Byte Order Marker
Specifies whether or not the GeoJSON writer should preface the JSON text with a byte order marker to indicate the endianness of the Unicode text. The default value is No.
JSONP
JSONP Function Name
Specifies the JSONP javascript function name that the user wants to wrap the GeoJSON file with. JSONP (JSON with Padding) is developed as a standard for grabbing GeoJSON from external domains, that works well with AJAX calls.
The default value is null. If no value is set or the default is set, then the GeoJSON writer will output a GeoJSON file without the JSONP padding. (optional)
