I can't believe people complain about the accuracy of this website. I measure buildings for real estate purposes, and I remember when there WAS NO WEB! This site is within 5% of actual size, based on my measuring here and then measuring the building on-site. If you want 100% accuracy go to the place you're measuring and measure it yourself!

Hey Respected Madam/Sir, I'm Niket from India,and doing project on land area measurement using GPS,Can you please give me information about by which method is use for measuring land area using latitude and longitude,there is any formula for that ? Thank You.
By Niket on 11/08/2015
if it is only an estimate what is the use of using this tool ?
By Samir on 08/08/2015
bonjour mes dames messieurs et medemoiselles il faut tout simlement savoir manupuler et prendre en consideration le point sur laquelle vous allez cliquer
By hajjaji on 07/08/2015
Hi Samir, the results should only be regarded as an estimate.
By Daft Logic on 05/08/2015
How accurate are these results, If i do the land survey usinf traditional method and compare the results with your website, how much will be the delta ?
By Samir on 05/08/2015
Hi, yes you can send your work via email.
By Daft Logic on 04/08/2015
I have made an account with draftlogic however I can't download this software but I was wondering if I will still be able to send my saved work via email to myself

Hi Klaus, This happens for certain areas when you zoom in. To switch the 45degrees view off, please use the drop down map at the top right of the map and untick the 45 degrees option.

Somebody ruined this site. Now when you zoom in it goes into perspective mode and you canīt measure a thing! Please fix it!

Christina, Please see this Capture
By Daft Logic on 30/07/2015
Hi there is no readout showing for the area below the map once i have marked the area.
By Christina on 30/07/2015
Hi Claudiu, thanks for the suggestion. We will look in to this.
By Daft Logic on 28/07/2015
Hi Crystal, the [Create New Area] button below the map should draw new areas. Are you using this? When you you say Save what do you mean? Thanks.
By Daft Logic on 28/07/2015
Can I save multiple areas? It appears to only save one area at a time. I'm trying to add up dozens of areas.
By Crystal on 28/07/2015
For the future, an interesting option should be able to select different versions of the maps. Ex. For a certain area there is a new map (2015), but very blurred, taken from high altitude. In Google Earth I found a version of the map from 2011 with many details for the same area.
By Claudiu on 28/07/2015
This is great! It helped me out so much thank you!
