Develop your own weather maps and alerts with Perl and GD

In this article, at IBM Developerworks, the author shows us how to use Perl and GD to do image processing on radar data. Here is the abstract:

Traditional weather reports will give notice of vague forecasts and severe weather alerts in your general area. The code and tools presented in this article will allow you to create precise detection zones so you can receive a page, SMS, or e-mail a few minutes before a precipitation event is likely to occur at the monitored location. Use GD and Perl for image processing of the NOAA WSR-88D radar data to create your own precipitation alerts for precise areas. Choose your notification method and let users know when the rain will begin and when it will clear.

    That's pretty cool. On a related note, anyone know where to get the raw data used to create the original images? Or if it's even reasonable or possible to get that data? Or what format it'd be in?

    UPDATE: er, no, I wasn't looking for images at all actually. Although, it would appear you can work backwards from the images to a certain extent. If these data were collected with public dollars, why do you have to pay to get the raw data? Suppose I want to study it and not just rely on the images someone else generated? I doubt you can get the data for free, I was just wondering if someone knew otherwise.

    Many government orgs are very open these days, the images alone are a huge step, so you never know.


      Hey i know its a little late to the game but it looks like you can get the data here its also got links to the formats the data are in, looks like a fun job to make a module for.
