Topic: Enviro Canada web developers have been busy .... Radar and Forecast

[mackbig]

Ken,
EC changed their site around, and the EC Forecast and Radar scripts are not working.
The radar one causes notices and warnings, the forecast is just null.

Let us know when you get a chance to have a look.

Thanks,
Andrew

Yep.. they've changed the website URL, and switched to UTF-8 for the charset (from ISO-8859-1).

I'll have to do some changes to both scripts.. working on it right now.

Best regards,
Ken

Just saw the mess on my site, thanks for getting right on it, Ken

[linuxfreak]

Well, at least they haven't mucked with the weather radio broadcasts yet.   

I just noticed the dashboard threw errors, guess a rewrite is needed for my EC-radar addon for NSDisplay! 

And I was just beginning to like spring!

Yes, ec-radar is next on my rework list based on Environment Canada changes today (16-Apr-2013)

I have completed the needed mods to ec-forecast.php (V2.14 - 16-Apr-2012)

Standalone users: get source or package from http://saratoga-weather.org/scripts-ECforecast.php#ECforecast
Template users: use http://saratoga-weather.org/wxtemplates/updates.php for Base-Canada, 16-Apr-2013

Note:  The EC has switched to using UTF-8 for their website so to retain the output as ISO-8859-1, a lot of iconv() calls
were added to the code.  I found at least one instance of the EC posting text with mixed UTF-8 and ISO-8859-1 special characters which chokes the current PHP versions of iconv() .. so if you see a detailed forecast with funny characters in it,
that's the native UTF-8 showing as the iconv() failed .. hopefully, the EC folks will use UTF-8 throughout their forecasts so that issue should be few and far between.
Also, the URLs changed from weatheroffice.gc.ca to weather.gc.ca .. if you use $ECURLs with the old address, the code will replace 'weatheroffice' with 'weather' in the URL so it should work fine.

After loading up the new ec-forecast.php on your site, run the page with ?cache to refresh the cache file and your forecasts should display again.

I should have a fix for the ec-radar issue(s) tomorrow (17-Apr-2013)

Best regards,
Ken

[weathergirl]

Thanks for the fix, Ken I notice they're using new icons as well:

http://weather.gc.ca/city/pages/on-47_metric_e.html

[saratogaWX]

I'll do a new icons set after the ec-radar script fixes

Best regards,
Ken

[weathergirl]

Yay!!! Thanks, Ken

[weathergirl]

Ken, I also noticed that the watches/warnings alerts bar is not displaying my location:

http://www.beamsvillewx.ca/index.php

[saratogaWX]

What was the code on your index.php that did the alerts display?  (BTW.. there aren't any alerts for your location right now)

[weathergirl]

Code: [Select]

if ($alertstring <> '') {
print $alertstring; // will produce alert box with link if advisories found
} else {
print "<p class=\"advisoryBox\">".langtransstr("No watches or warnings in effect for")." $title.</p>\n";

[saratogaWX]

I'll look at why $title is not being found later this evening. 

Best regards,
Ken

I have completed the needed mods to ec-forecast.php (V2.14 - 16-Apr-2012)

Thanks for the quick fix Ken, my EC forecast is back.

I should have a fix for the ec-radar issue(s) tomorrow (17-Apr-2013)

And as expected until you can get a fix for this, the radar is not working .

Ken, I also noticed that the watches/warnings alerts bar is not displaying my location:

We have no current watches or warnings and my home page does show the yellow bar with "No weather watches or warnings in effect for ,"

Also I did notice from my StatCounter that I had some visits from Environment Canada IP address earlier this morning,

www.google.ca — wxlink canada

which I have not seen before.

Thanks Ken

Andrew

[mackbig]

Strange.  It worked after I deleted the old ec-forecast-en.txt file.

Then a few hours laters, I went back in and it created a new null one again. Hmmm?

Andrew

[saratogaWX]

I have finished with the updates to support Environment Canada's new website design.   

ec-forecast.php V1.15 - 17-Apr-2013
  fixes the $title issue so alerts will show the name of the city
  Standalone users: get source or package from http://saratoga-weather.org/scripts-ECforecast.php#ECforecast

ec-radar.php V1.09 - 17-Apr-2013
  changes for new EC website design, UTF-8 to ISO-8859-1 conversion and a modified method for the /radar/ directory
  Standalone users: get source or package from http://saratoga-weather.org/scripts-ECradar.php#ECradar

Template users can get both scripts using the update tool for Base-Canada, 17-Apr-2013

Best regards,
Ken

[PaulMy]

Great, and seems to be working properly again.  Thanks again Ken.

Ken,
The radar script worked great.

I have this recurring problem with the forecast script.  It will work for a while.  Then my http://www.mackweather.com/ec-forecast-en.txt will end up like this below.

Great work, Ken, thanks. Have a look at my radar page-

http://www.beamsvillewx.ca/wxradar.php

The size of the map keeps changing

Very strange .. the 301 redirects to exactly the same URL ?!? -- I think this is a weather.gc.ca website problem. 
They appear to have two server addresses

04/18/13 07:59:29 dns weather.gc.ca
Canonical name: weather.gc.ca
Addresses:
  199.212.17.39
  199.212.17.28

and maybe this is a load balancing attempt if they are doing round-robin DNS for load balancing.

Great work, Ken, thanks. Have a look at my radar page-

http://www.beamsvillewx.ca/wxradar.php

The size of the map keeps changing 

I tried the page, and there are 3 different map sizes with their new website.
The NAT is 600x522px, the regional ones are 573x300px and the individual radar sites are 580x480px

Is that what you meant by 'the size of the map keeps changing'?

[weathergirl]

Yes.  I  have my ec-radar.php page set for my local radar, not the national or provincial radar,  so I wonder why it's displaying the national radar?

[saratogaWX]

Just did an update to wxadvisory.php for Base-Canada to fix the warning image overflow and correct links for new EC website design.

The wxadvisory.php main copy area now has

Code: [Select]

<div id="main-copy">
 
 
  <div align="center">       
<?php 
 $doInclude    = true; // handle ec-forecast and WXSIM include also
 $doPrint    = false; //  ec-forecast.php setting
 include_once($SITE['fcstscript']);
 if ($alertstring <> '') { 
 print $alertstring; // will produce alert box with link if advisories found
 } else { 
 print "<p class=\"advisoryBox\">".langtransstr("No watches or warnings in effect for")." $title.</p>\n"; 
 }
?>
<?php 
if(preg_match('|narrow|',$SITE['CSSscreen'])) {
$wtext = 'width="610" height="523"'; 
} else {
$wtext = 'width="852" height="731"'; 
}
if($SITE['lang'] == 'fr') {$L = 'f'; } else {$L = 'e'; } ?>
<a href="http://weather.gc.ca/warnings/index_<?php echo $L; ?>.html" style="border: none">
<img src="http://weather.gc.ca/data/download/canada.png" style="border:none;" <?php echo $wtext; ?> alt="national advisories"/></a>
<?php if($SITE['lang'] == 'fr') { $legend = 'CanadaLegend-fr.gif'; } else { $legend = 'CanadaLegend-en.gif'; } ?>
<img src="<?php echo $legend;?>" alt="National Advisory Legend" title="National Advisory Legend"/>
<?php print "<p><a href=\"$ECURL\">$ECNAME</a></p>\n"; ?>
  </div>
 
 
</div><!-- end main-copy -->


[saratogaWX]

Yes.  I  have my ec-radar.php page set for my local radar, not the national or provincial radar,  so I wonder why it's displaying the national radar?

Your Settings.php has

Code: [Select]

// radar settings for wxradar.php page
$SITE['ecradar']    = 'NAT';  // set to default Site for ec-radar (same as id=xxx on EC website)
so that is the default map that will be displayed on the wxradar.php page.

Best regards,
Ken

[weathergirl]

Have made the change to my Settings.php and ec-radar.php. My index page still has errors. I chose 'ONT' as my radar in my index.php.

Ann-Marie,
The messages

Notice: Undefined offset: 0 in /homepages/22/d364066440/htdocs/maps/ec-radar.php on line 265

Notice: Undefined offset: 0 in /homepages/22/d364066440/htdocs/maps/ec-radar.php on line 276

are there because the ec-radar.php in the /maps/ directory is the old one (not the updated one)

I suggest you either update the script in that directory, or better still, change the index.php to use the
new script in your home directory instead.

Best regards,
Ken
