It gives you exact measure specially when you are familiar with the map area you want to measure as I practiced that. It is a great program for settling dispute on land and the person who wants to know measurement of an area.

Kevbo, you can toggle the labels off using the drop down on the top left of the map.

Names of Buildings/businesses on map inhibits area calculation.
ie: can't place a marker flag over printed names

Hi ness-EE, thanks for the feedback the lat,lng is now the correct way round.
By Daft Logic on 9th January 2018
Your 'Latitude Longitude Output' is actually 'Longitude, Latitude'... other than that - amazing!! Would be nice to have a JSON output like

[{ "lat": 51.43783660584837, "lng": -0.2131819725036621 }]
By ness-EE on 9th January 2018
Very useful, thanks a lot!

Kentucky property is listed but has no data. All data against it is missing. Not sure why, but unfortunately there isn't much that can be done to retrieve it.
By Daft Logic on 30th December 2017
Awesome site. Had question ..... spent a good amount of time defining a property in KY usa ... Called Kentucky Property ...... after doing that property and a few variations of that property. I came to the site to revue the saved data and when I push the " Kentucky Property " button, I end up across the world in an island chain. Kentucky property gone ...?? Anything I can do about that ..?? Thanks ..

Hello, I wanted to calculate a piece of land, it gave an error I couldn't imagine of.
4 grid points, gave me about 70 acres. While using my maps on Google gave me 160 acres.
On 23rd December 2017
Would be great to have distance in (Unit) from one marker to another, on any side or any two marker points.

Is there any way i can have an updated satellite image for more exact area estimates??
By jade on 30th November 2017
It is an excellent tool and can be more effective if satellite images are up to date.
