Improved Feature and Potential Website Problems
I don’t know why but I seem to like this good news/bad news routine. I’ll
start out with the good but even the bad news isn’t really all that bad.
Snow Recording, Reporting and Displaying Improved
In the past, entering snow data was totally uncontrolled. Consequently,
volunteers could enter anything they wanted to represent the amount of
snowfall and we ended up with readings like 10”-12”, 10 in., 10 inches,
about 10 inches, approx. 10, etc. Obviously these types of readings made
it impossible to generate reports and maps. I spent quite a bit of time
cleaning up the records so they are all in a common format and also
developed error-checking routines to prevent these sorts of entries from
getting into the database again. As I observe other types of data entry
errors, I’ll add more code to the system to try to make this as
‘bullet-proof’ as the rain recording system.
I have also developed a couple of reports so you can see how much snow has
been occurring and additionally developed plotting routines to you can
seen on calendars and maps when and how much snow we have been having.
This has been integrated with the rainfall maps and charts so you should
be able to use these in the same manner you have been used to throughout
To view the data, go to ‘reports’ and select the ‘New Snow’ option to see
the calendar showing dates snow has been reported and what the maximum
amount was on each date. Then clicking on any colored box will take you
to the map for that date. Using the ‘maps’ option instead of ‘reports’
will take you straight to the maps if that is your choice. Another report
in the ‘reports’ section shows a summary of all the snow measurements in
Once the calendar view was completed, other entry errors such as snow
recorded in July and August were noted and corrected. These improvements
to the snow records have proven to be not only interesting but have
improved the data quality significantly as well.
Potential Website Problem
This is really not a significant problem but more of an advance notice
that as we move forward from 2004 to 2005, some features on the website
may not work properly without a little ‘tweaking’. If you do see any
problems, don’t worry about them. Next week I’ll be going through the
site to find any of those problems and fix them as I find them. If you
still see any problems after January 7, 2005, please do let me know though
because that probably means I have not detected them yet.
Thanks again for volunteering for NeRAIN.
