Rails Geokit 将 GPS 坐标转换为 Google 经纬度

发布于 2024-10-20 22:44:07 字数 146 浏览 1 评论 0原文

我从 Tom Tom 设备获得了 GPS 位置，

S 33 22' 7.08",E 19 55' 27.44"

我需要将其转换为谷歌经纬度。有谁知道有一个有效的 gem 可以做到这一点或能够进行转换的代码片段

我不知道 Ruby on Rails，但我有一个 PHP 版本，用于将 DMS（度/分/秒）转换为十进制纬度/经度。也许你可以将其转换为 RoR 版本。请注意，代码不会检查（剥离）分钟和秒后的“”或“”。您可能需要为您的语法添加此内容。

// Converts DMS ( Degrees / minutes / seconds ) 
// to decimal format longitude / latitude
function GPS_DEC($coord)
{
    $n = explode( " ", trim( $coord ) );
    if ( count( $n ) == 1 )
        return $coord;

    $deg = $n[ 0 ];
    $min = $sec = 0;
    if ( !is_numeric( $n[ 1 ] ) )
        $dir = $n[ 1 ];
    else
    {
        $min = $n[ 1 ];
        if ( !is_numeric( $n[ 2 ] ) )
            $dir = $n[ 2 ];
        else
        {
            $sec = $n[ 2 ];
            $dir = $n[ 3 ];
        }
    }

    $dec = $deg+((($min*60)+($sec))/3600);
    if ( $dir == 'S' || $dir == 'W' )
        $dec = -$dec;
    return $dec;
}

I don't know Ruby on Rails, but I have a PHP version for converting DMS (Degrees/Minutes/Seconds) to Decimal lat/lng. Perhaps you can convert it to RoR version. Note, the code does not check (strip) for a ' or "" after the minutes and seconds. You may need to add this for your syntax.

// Converts DMS ( Degrees / minutes / seconds ) 
// to decimal format longitude / latitude
function GPS_DEC($coord)
{
    $n = explode( " ", trim( $coord ) );
    if ( count( $n ) == 1 )
        return $coord;

    $deg = $n[ 0 ];
    $min = $sec = 0;
    if ( !is_numeric( $n[ 1 ] ) )
        $dir = $n[ 1 ];
    else
    {
        $min = $n[ 1 ];
        if ( !is_numeric( $n[ 2 ] ) )
            $dir = $n[ 2 ];
        else
        {
            $sec = $n[ 2 ];
            $dir = $n[ 3 ];
        }
    }

    $dec = $deg+((($min*60)+($sec))/3600);
    if ( $dir == 'S' || $dir == 'W' )
        $dec = -$dec;
    return $dec;
}
