Draw Polygon On Map With Coordinates

I would like to add my polygons on a map. A polygon is a shape consisting of a series of coordinates in an ordered sequence, similar to a polyline. I have a custom google maps using my maps which has some polygons (around 18) and i would like to get the coordinates of each polygon without having to place markers on every corner.

A polygon (like a polyline) defines a series of connected coordinates in an ordered sequence.

One thing i noticed is that die jsonarray coordinates contains null references. This is an example of the polygons i want to get the coordinates. Would need to convert to the csv to kml before import. Is there an easy way to draw land plots in google earth using coordinates for each point of the polygon?
