I saw this map before when my colleague Georgi Pavlov (www.HumaDesign.org) shared it with me asking my opinion.
Its seems clear to me that this particular contour map is a classic case of where the methods of extracting/making contours from GoogleEarth/Maps just doesn't work...they are inherently unreliable — you are much better off either getting a survey done or using the available county/state/federal photogrammetry or Lidar based data where possible.
Regarding locating the Keypoint – I can save a bit of time here by pasting in a few extracts from the recently released 2. Geography chapter of the Regrarians eHandbook.
