How to Use

  • The calculated area will then be displayed below the map

Other Options

  • Click [Delete Last Point] to remove the last point clicked
  • Click [Clear All Points] to remove all areas drawn
  • Click [Generate KML] to generate a KML file representing the last area drawn. Once you click this option, after a short delay, a hyperlink "Download KML File Here" will appear. From this link, you can download your KML file
  • Click [Create New Area] to start drawing anew area whilst keeping any existing areas on-screen
  • You can adjust the map size by clicking Small, Medium, Large or Full Screen

Thank you very much for putting this out. Super user friendly and an awesome resource!
By Tyler on 26/03/2015
Very nice, useful tool. Would love to be able to export area info to Office or Google docs. Am I missing that?

I was looking for this kind of tool for a long time. It is excellent, and if the marking on the map is done correctly, the area calculated is very accurate. I am very happy and thanks to Google.

TLC/JimmyB here - Why will it not drop a pin on the actual address, like Google Maps does?
On 23/03/2015
Would be amazing for work if it displayed addresses somehow.
On 22/03/2015
thanks.very usefull

This is really nice; except it does not allow one to save the photo for further use in "My Pictures." I cannot just select the photo of the map without having to go into the Google Area Map site, and I cannot upload it in other applications.
By David on 21/03/2015
JimmyB, yes, it will only zoom in as far as street level.
By Daft Logic on 21/03/2015
TLC, these address are found OK as far as I can see. So when you click Search nothing happens?
By Daft Logic on 21/03/2015
try any of these: 345 Berkshire Dr Covington, GA; 2011 Old Salem Rd Conyers, GA; 1037 Meadow Springs Dr Conyers, GA
By TLC on 19/03/2015
This is great but I have one problem. It does not drop a pin on the exact property location. It show the street/area but if I don't know the specific house, I don't know which property to measure. Am I doing something wrong?
By JimmyB on 19/03/2015
i do not get it-square miles
By kyra on 19/03/2015
Hi TLC, what address are use using?
By Daft Logic on 18/03/2015
The map does not display a pin for the exact address. I have to go to another program to get the exact location of the address, then look at this app. Am I doing something wrong?
By TLC on 18/03/2015
fihe :)
By joao on 16/03/2015
I think there's a mistake in calculation. The Earth is about 57 million or so square miles big. If I look up for points in the Pacific, I get a square mileage of over 31 million. On the map, it looks more like 1/8th or even less big, yet it's over half of the earth?
By Jay on 15/03/2015
Thank you. Looking at land and am able to see how big of a cleared area is on a property.

Hi goose, when there are 2 points the perimeter measurement reads twice the distance between them. If you are looking to measure distances, please use the Distance Calculator.
By Daft Logic on 07/03/2015
great for getting square footage and total perimeter. having trouble getting accurate distance from pt A to pt B..seems way off in distance when doing just 2 points? cannot use for diagramming due to this.
By goose on 06/03/2015
Great product no more walking with a wheel.
By no tired feet on 05/03/2015
any updates for this ?
