我试图从图像中获取纬度和经度。 exif gps数组:

   [GPS] => Array
    (
        [GPSVersion] => 
        [GPSLatitudeRef] => N
        [GPSLatitude] => Array
            (
                [0] => 57/1
                [1] => 42/1
                [2] => 45594/1000
            )

        [GPSLongitudeRef] => E
        [GPSLongitude] => Array
            (
                [0] => 11/1
                [1] => 54/1
                [2] => 56615/1000
            )

        [GPSAltitudeRef] => 
        [GPSAltitude] => 228/10
        [GPSTimeStamp] => Array
            (
                [0] => 10/1
                [1] => 46/1
                [2] => 12000/1000
            )

        [GPSStatus] => A
        [GPSMeasureMode] => 3
        [GPSSpeedRef] => K
        [GPSSpeed] => 4/10
        [GPSTrackRef] => T
        [GPSTrack] => 1719/100
        [GPSImgDirectionRef] => M
        [GPSImgDirection] => 32900/100
        [GPSMapDatum] => WGS-84
        [GPSDateStamp] => 2011:04:23
        [GPSDifferential] => 0
    )

我认为纬度是45594/1000和经度56615/1000,但这些值似乎是这样的。我做错了,还是数据不正确?感谢

1 个答案:

答案 0 :(得分:0)

我会解释: [GPSLatitudeRef] => N [GPSLatitude] => Array ( [0] => 57/1 [1] => 42/1 [2] => 45594/1000 ) 北纬为57度,42分钟,45秒和594毫秒...... Ergo:在加拿大或西伯利亚的某个地方。

下一个问题是“基准是什么?”,在[GPSMapDatum] => WGS-84元素中给出。

干杯。基思。

PS:谷歌(WGS-84)说:http://en.wikipedia.org/wiki/World_Geodetic_System

PPS:看http://www.worldpress.org/images/maps/europe_600w.jpg,我把这一点放在靠近挪威海岸的北海......我温暖吗?
