Google API を使用すると、特定の住所の座標を取得できると思います。ただし、私が見つけたほとんどの (またはすべてと言うべきです) 例は、vb 用ではありません。通常、私を混乱させるのはJavaScriptの例です。
これは、ジオコーディング サービスを使用するコードです。これはうまくいきます。自分で直接 Google マップにクエリを実行したいだけです。
Public Function fgGetLatAndLongUsingAddress(sAddress As String) As String
'This function works best with a complete address including the zip code
Dim sResponseText As String, sReturn As String
sReturn = "none"
Dim objHttp As Object, sQuery As String
sQuery = "http://rpc.geocoder.us/service/csv?address=" & Replace(sAddress, " ", "+")
Set objHttp = CreateObject("Msxml2.ServerXMLHTTP")
objHttp.Open "GET", sQuery, False
objHttp.send
sResponseText = objHttp.ResponseText
gsLastLatLongResponseText = sResponseText
