This is the README file for wxecradar scripts (Environment Canada Radar display using HAniS).

As of 30-Mar-2021, Environment Canada changed their Radar website to use a map to display radar information, and
stopped publishing radar images as .gif files on their main website.  This rendered the former display script
of ec-radar.php obsolete and non-functional (since the images were no longer available).

Fortunately, the radar .gif images continue to be published on https://dd.weather.gc.ca/radar/PRECIPET/GIF/{sitename}/
BUT sadly, they no longer have the detail overlays of towns, highways, rivers on the new maps. So, the new .gif
radar images are a bit sparse but do otherwise display the 14-color versions of the original .gif images.

Contents:
  wxradar.php       (the linked-to script from the menu for radar display in Base-Canada template)
  wxecradar-inc.php (provides selection capability and <iframe> for HAniS display)
  wxecradar-iframe.php (provides contents to display in the <iframe>)
  wxecradar-list-inc.php  (list of current radar stations for display)
  hanis_min.js      (the HAniS script)
  wxindex.php       (updated to use wxecradar-iframe.php to display a radar image set)

All the files should be in the same directory (normally, the document root of the website).

If manually converting from an older wxindex.php to the new one, just replace:

------
			<?php 
			// fetch fresh national radar image if needed .. you can chang it to
			// 'NAT' = National radar view
			// 'PAC' = Pacific region
			// 'WRN' = Praries region
			// 'ONT' = Ontario
			// 'QUE' = Quebec
			// 'ERN' = Atlantic region
			  $_REQUEST['site'] = 'NAT'; // one of the sites above, or your radar designator
			  $doPrint = false;
			  include_once("ec-radar.php");
			?>
			<img src="<?php echo $radarDir . 'radar-' . $_REQUEST['site'] . '-0.png'; ?>" 
			alt="Radar, courtesy of Environment Canada"
			title="Radar, courtesy of Environment Canada" /> 
------

with 

------
			<?php 
			// fetch national radar image if needed
			// 'PYR' = Pacific region
			// 'PNR' = Praries region
			// 'ONT' = Ontario
			// 'QUE' = Quebec
			// 'ATL' = Atlantic region
			// or use the local radar site code like WKR or CASET .. see wxecradar-list-inc.php for codes

			  $radarLoc = 'ONT';
				
			//  $radarLoc = $SITE['ecradar']; // use Settings.php entry	
				$radar='RAIN'; // ='RAIN' or ='SNOW';
			?>
<iframe name="wxradarshanis" width="617" height="<?php echo (in_array($radarLoc,array('PYR','PNR','ONT','QUE','ATL')))?'380':'555';?>" src="./wxecradar-iframe.php?radar=<?php echo $radar?>&amp;radarLoc=<?php echo $radarLoc?>&amp;lang=<?php echo $SITE['lang']; ?>" scrolling="no" style="border:none"></iframe>
------

Your Settings.php entry of:

  $SITE['ecradar'] = 'WKR';

will determine the selected site in wxradar.php display
