Parameters:

url - KML/KMZ url

Throws:

IOException - if creating stream failed

extractKmlStream

public static InputStream extractKmlStream(InputStream kmzInputStream)
                                    throws IOException

Gets KML input stream from KMZ stream.

Parameters:

kmzInputStream - KMZ stream

Returns:

encoded input stream containing KML data

Throws:

IOException - extracting KML stream fails

convertToFeaturesStream

public static InputStream convertToFeaturesStream(InputStream kmlInputStream,
                                                  String rootUrl)
                                           throws IOException

Drills-down KML stream for "Placemark" and follows "NetworkLink". THis method ALWAYS closes input stream passed as an argument.

Parameters:

kmlInputStream - KML input stream

rootUrl - root URL used when KML contains relative URL

Returns:

first found feature stream.

Throws:

IOException - if convertiong stream fails
