Weather Data Available in XML

wombatmobile writes "Wired reports the National Oceanic and Atmospheric Administration this week began providing weather data in an open access XML format. Previously, the data was technically available to the public, but in a format that's not easily deciphered. How will the free and easy availability of valuable data like this in XML affect the development of the web? One example is Tom Groves SVG weather. This type of visualization of XML data is about to fall within easy reach with nothing more than a text editor required as an authoring tool. From March 2005 SVG becomes part of the standard Mozilla/FireFox build. As an example of how web standards are supposed to work, what more could you hope to find?" We mentioned the policy change a few days ago.

Click on a city in your area on this site: http://www.timeanddate.com/worldclock/custom.html? continent=namerica The page for each city lists the coordinates.

Extension for Firefox

[FiReaNGeL]

Don't miss out the wonderful WeatherFox extension for Firefox... crafteh coded this marvel after a suggestion of mine on Mozillazine Forums. International Forecast in your statusbar. Can't beat that!

[MP3Chuck]

Except that now it's ForecastFox. Apparently there was some conflict with the website www.weatherfox.com (people going to weatherfox.com looking for WeatherFox extension support 'n stuff).

Re:What's my lat and alt?

Yeah, you are right... that's the only information I need to chunk out a quick program running off the feed.

Speaking of the feed...here's the URL that contains the actual XML information:
http://www.nws.noaa.gov/forecasts/xml/

I guess they didn't post it on the front page to decrease the slash effect.

Re:Why SOAP

[aluminum boy]

SOAP, being XML, is available via http. Anything available in SOAP can be opened / viewed as XML in most browsers.

NOAA servers contain much more weather info than just US states and territories; my program was pulling down everything from Afghanistan to Zimbabwe. Which was good for me - the site was designed for world travelers.

URL for HTTP-fetchable XML

[ErichTheWebGuy]

http://weather.gov/data/current_obs/seek.php

The URL points to the RSS versions of the XML feeds. These have actually been available for quite some time.

Re:SVG plugin for firefox?

[g_braad]

You need to recompile Firefox yourself or download the older 0.8 release from Mozilla.org which has SVG enabled.

http://mozilla.org/projects/svg/

another solution is to install svgview from adobe, like the 6.0 beta 1 and coppy the plugin files found in /progra~1/common files/adobe/adobe viewer 6/plugins/np* to the plugins dir from firefox (ofcourse only on windows).

if you want to use the mozilla implementation of SVG, recompile is the only solution for now. is there someone out there who would be willing to create this so-called 'patch'?

weather.com been doing this for a while

I set up a little script a long time ago to get weather data from an XML feed from the weather channel for our office webcam. It's free and was really easy to use...

http://www.weather.com/services/xmloap.html?

#!/usr/local/bin/perl -w
require LWP::UserAgent;
use XML::DOM;
use CGI qw(:standard);
# first, get the XML feed
my $ua = LWP::UserAgent->new(env_proxy => 1, keep_alive => 1, timeout => 30);
my $base_url="http://xoap.weather.com/weather/local/6 0143?cc=*&prod=xoap";
my $par="&par=[removed]";
my $key="&key=[sign up to get one]";
$response = $ua->get("$base_url$par$key");
die "Error while getting ", $response->request->uri,
" -- ", $response->status_line, "\nAborting"
unless $response->is_success;
my %weather = %$response;
# then, parse out the crap we want
my $parser = XML::DOM::Parser->new();
foreach(keys %weather){
$xmldoc = $parser->parse($weather{$_}) if(/content/);
}
foreach my $cur_cond ($xmldoc->getElementsByTagName('cc')){
$curr_cond{'lastup'} = $cur_cond->
getElementsByTagName('lsup')->item(0)->
getFirstChild->getNodeValue;
$curr_cond{'obsvst'} = $cur_cond->
getElementsByTagName('obst')->item(0)->
getFirstChild->getNodeValue;
$curr_cond{'temp'} = cur_cond->
getElementsByTagName('tmp')->item(0)->
&nb s p; getFirstChild->getNodeValue;
$curr_cond{'chill'} = $cur_cond->
getElementsByTagName('flik')->item(0)->
getFirstChild->getNodeValue;
$curr_cond{'text'} = $cur_cond->
getElementsByTagName('t')->item(0)->
getFirstChild->getNodeValue;
$curr_cond{'icon'} = cur_cond->
getElementsByTagName('icon')->item(0)->
getFirstChild->getNodeValue;
}
print header;
print start_html("nice little cgi page to display the time/weather");
print <<EOF;

sorry about the atrocious formating - slashcode made me take out whitespace (what is the fricking point of an ecode tag supported if you can't post a small snippet like this without removing all the whitespace!?)
