How to display weather radar map on website?
提问by candyA
I'm specifically looking for a weather radar map, similar to this one to display on a Wordpress website: http://www.vantilburgfarms.com/weather_local_radar.htm
我正在专门寻找天气雷达地图，类似于在 Wordpress 网站上显示的地图：http: //www.vantilburgfarms.com/weather_local_radar.htm
The radar above is animated and zoomed in on the Indiana, Ohio part of the US, which is exactly what I need. I don't want to steal this map from the website.
上面的雷达动画并放大了美国俄亥俄州印第安纳州的部分，这正是我所需要的。我不想从网站上窃取这张地图。
I've Googled this and the only things I can find are 5-day forecasts. Any suggestions?
我在谷歌上搜索过这个，我唯一能找到的就是 5 天的预测。有什么建议？

Looking at their page source, it's setup like so:
查看他们的页面源，它的设置如下：
<a href="http://www.tephigram.weather.net/cgi-bin/razradar.cgi?zipcode=45822&width=720&height=486" target="main">
<img border="0" dynsrc="http://www.tephigram.weather.net/cgi-bin/razradar.cgi?zipcode=45822&width=720&height=486" start="fileopen" src="http://www.tephigram.weather.net/cgi-bin/razradar.cgi?zipcode=45822&width=720&height=486">
</a>
Which sources this site:

Via dynsrc:

Basically, they're setting a regular old <img>'s source to be an external video clip.
基本上，他们将常规的 old<img>源设置为外部视频剪辑。
Ironically, it looks like they're stealing it.
具有讽刺意味的是，看起来他们正在窃取它。

Check out the National Weather Service radar: http://radar.weather.gov/radar.php?rid=LOT&product=N0R&overlay=11101111&loop=yes

If you fire up something like Fiddler, you can see the requests for the individual images being used to make the "loop". In the past, I have created something where these frames were cropped to a specific area, and then placed into an animated GIF. This is trivial with ImageMagick, or GD, which are generally available in PHP. You could also do this with JavaScript if you were crafty with DIV overflow.
如果您启动类似 Fiddler 的工具，您可以看到对用于制作“循环”的单个图像的请求。过去，我创建了一些东西，将这些帧裁剪到特定区域，然后放入动画 GIF 中。这对于 ImageMagick 或 GD 来说是微不足道的，它们通常在 PHP 中可用。如果您对 DIV 溢出很熟练，也可以使用 JavaScript 执行此操作。
As for licensing, I believe you can use it without a license, but you should check with a lawyer who knows for sure. I am not one.
至于许可，我相信您可以在没有许可的情况下使用它，但您应该向确定的律师咨询。我不是一个。

The animations created by the NWS use a flash program called FLAnis, you can find more here: http://www.ssec.wisc.edu/flanis/It is VERY easy to use and configure.
