WSR-88D

This was an early proof of concept to decode WSR-88D Nexrad radar data obtained from NOAA. While the data structure of the radar product files should ramain the same, it is possible that the mappings are dated, as this was developed in 2010. Do not expect further updates within this repository.

Usage

Further examples may be found within the examples/ folder.

include('classes/NexradDecoder.php');
include('classes/RasterPacketDecoder.php');


$reflectivityDecoder = new RasterPacketDecoder();
$reflectivityDecoder->setFileResource('/tmp/sn.last');
$headers = $reflectivityDecoder->parseMHB();
$description = $reflectivityDecoder->parsePDB();
$symbology = $reflectivityDecoder->parsePSB();
if($description['graphicoffset'] != 0)
{
	$graphic = $reflectivityDecoder->parseGAB();
}
