The following example illustrates the format and naming conventions used
at the WCATWC.  Sea-level data is logged to disk in station specific
files.  Filenaming conventions encode the site name, date, year, and
data type into the file name.  For example,

 adak_A_2007.134

where:
	adak	is the site abbreviation,
	A	is the sensor being recorded
	2007	is the year, and
	134	is the julian day

Each file is prefaced with four header lines followed by the data.

The header format is:
Line 1:	SiteName PlatformID Operator TransmissionType Latitude Longitude Date
Line 2:	SensorType WaterLevelUnits TimeZone SampleRate SampleRateUnits ReferenceDatum RecordingAgency ProcessingInfo
Line 3:	Comment
Line 4:	Data Format


The following listing shows the header lines and the first and last five
data values for the adak file used as an example above:
