Description

NOAA-18 data cannot be opened using L1B/NOAA Dirver, because the function L1BDataset::DetectFormat()​https://trac.osgeo.org/gdal/browser/trunk/gdal/frmts/l1b/l1bdataset.cpp#L3024. failed to detect corresponding file format. To solve this problem, we can add a judgement on new file format in the function L1BDataset::DetectFormat(), and return L1B_NOAA15_NOHDR. For example: 

	// try NOAA-18 formats
	if ( *(pabyHeader + 0) == '\0'
		&& *(pabyHeader + 1) == '\0'
		&& *(pabyHeader + 2) == '\0'
		&& *(pabyHeader + 3) == '\0'
		&& *(pabyHeader + 4) == '\0'
		&& *(pabyHeader + 5) == '\0'
		&& EQUALN((const char*)(pabyHeader + 22), "/N1BD/N18/", 10))
		return L1B_NOAA15_NOHDR;
