Draw level curves of 2 farms, 1 farm of approximately 150 hectares and another of approximately 720 hectares.

I will provide the coordinates of the perimeter of the 2 farms and I need the level curves meter by meter of the entire area of the two farms and on a scale of 1:10000, the level curves data can be obtained free from google earth or other satellite aplications, I need the file in autocad format so I can print it.
