Where is the Data Stored

The data is stored in the Application Data folder. On many versions of windows, you can get there by typing %PROGRAMDATA% into the run box, or the address bar of an explorer window.

Our data is stored a couple of sub folders down in:
%PROGRAMDATA%\Wieser Software\MetStats

How is the data stored?

The data is stored in an SQL Server Compact Edition 3.5 SP1 Database. This format allows you to access the data from your own programs as well as from ours, so you can examine the historic data in any way you like.

The data is stored in a table created thus:

            CREATE TABLE WeatherSamples 
                (SampleTime datetime not null, 
				TempIn real, TempOut real, 
				avgWind real, gustWind real, 
				accumRainfall int, pressure real,
				humidIn tinyint, humidOut tinyint,
				windId tinyint,
				sampleInterval tinyint not null)
		

Accumulated rainfall is stored as the number of bucket drops seen (which on the Watson is .3mm each drop)

What other files are located there?

The W8681-Dump file is the state of the weather station's memory the last time it was downloaded.

The html folder

Below that is a folder named html. This folder contains the current weather sample in XML format, as well as the transformations and images.

It also contains a few files for your website, including a .htaccess file for apache sites to configure how xlst files are served,
