使用 PHP 的 picasa API 从 picasa 图像中获取纬度/经度（地理标记）

我到处寻找这个简单任务的答案，但没有成功。

我只需要从图像中获取纬度/经度（地理标记）。该文档给出了如何更新 GeoRssWhere 中的 GmlPos 的示例。 ( http://code.google.com/apis/picasaweb/docs/ 1.0/developers_guide_php.html ）但是如何检索该信息呢？

我尝试了以下方法，但我认为我出了问题。

  $where = new Zend_Gdata_Geo_Extension_GeoRssWhere();
  $georeff = $where->point;

有人可以帮忙吗？

I have looked everywhere to try and get the answer to this simple task to no avail.

I just need to get the lat/long (geotag) from an image. The docs give an example of how to update the GmlPos in the GeoRssWhere. ( http://code.google.com/apis/picasaweb/docs/1.0/developers_guide_php.html ) But how do you just retrieve that info?

I'v tried the below, but I think i'v got something wrong.

  $where = new Zend_Gdata_Geo_Extension_GeoRssWhere();
  $georeff = $where->point;

can someone help?

我发现了一个很好的例子，让地理标记在地图上显示照片，就像我想做的那样。 http://picasaphpworkshop.googlecode.com/svn-history/r11/trunk /workshop.php

我无法弄清楚的部分是 $where->getPoint()->getPos();得到georsshwere后。

Zend_Loader::loadClass('Zend_Gdata_Media_Extension_MediaKeywords');
 Zend_Loader::loadClass('Zend_Gdata_Geo_Extension_GeoRssWhere');
 Zend_Loader::loadClass('Zend_Gdata_Geo_Extension_GmlPos');
 Zend_Loader::loadClass('Zend_Gdata_Geo_Extension_GmlPoint');
 Zend_Loader::loadClass('Zend_Gdata_Photos_PhotoEntry');


 $picasa = new Zend_Gdata_Photos();
 $query = $picasa->newAlbumQuery();
 $query->setUser('[email protected]');
 $query->setAlbumName('MyAlbumNameFromURL');
 $feed = $picasa->getAlbumFeed($query);

 foreach($feed as $num => $photoEntry){

           $where = $photoEntry->getGeoRssWhere();
            $lat = $where->getPoint()->getPos();
            //$lat = split(" ", $lat); // Split out the space-separated lat

 }


echo "GeoReff: " . $lat . "<br />\n";

I found a great example getting geotag to display photos on a map like I wanted to do. http://picasaphpworkshop.googlecode.com/svn-history/r11/trunk/workshop.php

The part I couldn't figure out was the $where->getPoint()->getPos(); after getting the georsshwere.

Zend_Loader::loadClass('Zend_Gdata_Media_Extension_MediaKeywords');
 Zend_Loader::loadClass('Zend_Gdata_Geo_Extension_GeoRssWhere');
 Zend_Loader::loadClass('Zend_Gdata_Geo_Extension_GmlPos');
 Zend_Loader::loadClass('Zend_Gdata_Geo_Extension_GmlPoint');
 Zend_Loader::loadClass('Zend_Gdata_Photos_PhotoEntry');


 $picasa = new Zend_Gdata_Photos();
 $query = $picasa->newAlbumQuery();
 $query->setUser('[email protected]');
 $query->setAlbumName('MyAlbumNameFromURL');
 $feed = $picasa->getAlbumFeed($query);

 foreach($feed as $num => $photoEntry){

           $where = $photoEntry->getGeoRssWhere();
            $lat = $where->getPoint()->getPos();
            //$lat = split(" ", $lat); // Split out the space-separated lat

 }


echo "GeoReff: " . $lat . "<br />\n";
