Are there any specific rules or additional considerations when converting GPS coordinates to decimal numbers for use in Google Maps or other mapping services?

When converting GPS coordinates to decimal numbers for use in mapping services like Google Maps, it's important to remember that latitude and longitude values have different ranges and formatting requirements. Latitude values range from -90 to 90, while longitude values range from -180 to 180. Additionally, latitude values are usually listed first in GPS coordinates, followed by longitude values. To convert GPS coordinates to decimal numbers for use in mapping services, you can use the following PHP code snippet: 

function convert_gps_to_decimal($lat_deg, $lat_min, $lat_sec, $lon_deg, $lon_min, $lon_sec) {
    $lat_decimal = $lat_deg + ($lat_min / 60) + ($lat_sec / 3600);
    $lon_decimal = $lon_deg + ($lon_min / 60) + ($lon_sec / 3600);
    
    return array('latitude' => $lat_decimal, 'longitude' => $lon_decimal);
}

// Example usage
$gps_coordinates = convert_gps_to_decimal(37, 45, 15, -122, 25, 30);
echo 'Latitude: ' . $gps_coordinates['latitude'] . ', Longitude: ' . $gps_coordinates['longitude'];
