Can you show us what exactly is the string you receive? Maybe you will have to do a converter which suits you. Cheers – Petar Stojanovski Mar 08 '19 at 10:34

Please take a look at [this](https://stackoverflow.com/questions/4983766/getting-gps-data-from-an-images-exif-in-c-sharp) to see if it is really this you're trying to do. – Lasse V. Karlsen Mar 08 '19 at 10:35

Are you asking how you can parse and tokenize a string? – Kieran Devlin Mar 08 '19 at 10:42

You need to use this simple formula, after extracting values from string.
Dim strGPS As String = "Latitude: 34 deg 30' 28.71"" N"
Dim degrees As Double = CDbl(strGPS.Split(Space(1))(1)) '34
Dim minutes As Double = CDbl(strGPS.Split(Space(1))(3).Replace("'", "")) '30
Dim seconds As Double = CDbl(strGPS.Split(Space(1))(4).Replace("""", "")) '28.71
MsgBox(degrees + (minutes / 60) + (seconds / 3600))

added simple code in VB.NET to extract values from string; you can find better method if you need/want. – tezzo Mar 08 '19 at 10:50
