Set point to right latitude/longitude place?


I would like to create site plan design. I have added from google maps right region and now I want add boundaries of my property on this map picture. How I can set lines or points right placies if I know real latitude and longitude values of those boudary markers?


@Geo could probably help, and did in this thread: Can I enter coordinates (2d) into SketchUp (Could be UTM or Lat/Long)?
