Description

When RSS 1.0 is used to dissemenate data from a weather station, this module provides additional information about the feed only of interest to specialist clients, such as information about the exact location of the station and information about the accuracy of the data.

stationLatitude

The latitude of the station expressed in degrees concatenated with minutes and decimal fractions of minutes. e. g. 01545.123N is Latitude 15 deg 45.123' N

stationLongitude

The longitude of the station expressed in degrees concatenated with minutes and decimal fractions of minutes. e. g. 01545.123E is Longitude 15 deg 45.123' E

stationElevation

The elevation of the station expressed in metres above or below mean sea level.

updateValue

The value of each reading - theoretically, the value of the reading referenced by the linked page.

updateResolution

The resolution of each reading expressed in the same units as the reading itself.

updateAccuracy

The accuracy of each reading expressed in the same units as the reading itself.

updatePeriod

The period between readings expressed in seconds.

updateTime

The exact time of the last reading to the nearest second UTC expressed in the form 2005-01-20T16:30:45Z

stationCaldate

The date of the last station calibration.

stationCaltype

The standard of calibration used.
