Use site with Google Maps plugin to estimate Elevation Data
Attempting to put together a plot plan with terrain elevation this weekend, I came across this site that I thought was handy.

It isn't an elegant site, but you can enter the address for the property that you are working on and simply click the image to find the elevation for that "point". I was able to put together a reasonable terrain in Chief quickly using this tool.
Certainly not great for a final project, but a good start for
Here is the way!
First point some points here to determine min and max ranges for latitude and longitude (it will be a rectangular field at finish)

Even two points will be enough by diagonal of a rectangular. Also you can use any other service to determinate coordinates in decimal format. GoogleMaps for example.
So now you have information about latitude range - from/to and about longitude range.
