[SOLVED] Coordinate conversion

[hellouthere]

Hi all,

    I need a function that will convert a latitude/longditue stored in the variable $position in the format "N50 43.9122 W3 25.6329" to two seperate coordinates $lat and $long which can be read by the google maps api... http://www.google.com/apis/maps/documentation/

 

thats all the information i have... Thanks in advance...

A minute is 1/60 of a degree so 43.9122 / 60 = 0.73187

 

$lat = ($degrees + ($minutes/60));

the variable is in that format and i cant change it.... i need to be able to split it... i can use the full stops but i cannot get the N50 apart... any ideas for that?

<?php

$position = "N50 43.9122 W3 25.6329";

list ($n, $lat, $w, $long) = explode (' ', $position);

echo $lat, '<br/>';       //  43.9122
echo $long, '<br/>';      //  25.6329

?>

o may be mising omething but that still leaves the problem of not having acces to the 50 seperately... i have trried using barands "explode with the /60 but the coordinates are not "corrrect" as it were not sure whether its actually possible...

 

i have woprked out that the coordinate that i need from the above example are... lng="-3.427215" lat="50.73187"

 

the function needs to seperate the N50 from the 43.9122... DONE

divide the 43.9122 by 60... DONE

add the 50 (from the N50)... ???

work out whether the final rersult is + or - based on the W/E (W is negative i think)... ???

 

hmm im lost

given that you start with

 

$position = "N50 43.9122 W3 25.6329";

 

What, precisely, do you want to end up with?

[Barand]

do you mean

 

<?php

$position = "N50 43.9122 W3 25.6329";

list ($n, $latmin, $w, $longmin) = explode (' ', $position);

printf ('%s, %d, %f<br>', $n{0}, substr($n,1), $latmin);
printf ('%s, %d, %f<br>', $w{0}, substr($w,1), $longmin);

?>

 

-->[pre]

N, 50, 43.912200

W, 3, 25.632900
