[Map Height : Small - Medium - Large - Full Screen]

Output : Current Area

0 m² | 0 km² | 0 acres | 0 hectares | 0 feet² | 0 square miles | 0 square nautical miles

Add a location manually (also accepts [latitude,longitude])


How to Use

Hi Jo, can you confirm which device and web browser you are using please?

Hi Jo, thanks for the feedback. We will look in to this.
By Daft Logic on 9th May 2018
from the page "https://www.daftlogic.com/user.htm" clicking "export XLSX" of user-created areas the downloaded file is a .zip archive and not .xlsx. Changing the extension manually works as intended and can open the spreadsheet.

wow... best website for surveying, so easy to get data about area calculation..
thank you
By Infosipil on 7th May 2018
Hi. Please add an option to import lat/long or a kml file to possibly edit in this tool for later export. Thanks!!!

Hi Adam, Thanks for the feedback. Yes, this is on the to-do list.

I%u2019d like to know the length of the lines so I can see the area is for example 20 metres by 17metres
On 28th April 2018
Excellent tool and resource! I second the request to have multiple areas able to be saved as one project. It seems the generated KML might export all points but the save option doesn't retain all areas. Thank you!!!

This tool is A.M.A.Z.I.N.G.!!

Hi, this is a great tool, but any idea when multiple areas to be added to a project, then saved will be working ?
By Russ Davison on 16th April 2018
Excellent tool! Thanks!

What is the accuracy resolution of this tool?
I see 14 digits in decimal places after the decimal point.
So what is the error in the 14th digit?
By Chanakya K V on 6th April 2018
Brooks, it is still available but will only become available when the there is imagery available to do it. It is more likely to work on high zoom and when looking at densely populated areas.
By Daft Logic on 27th March 2018
There used to be a button to rotate the view. Was that removed?
By Brooks Wedeking on 27th March 2018
There is an option to include them in the original measurement. Then measure the islands and subtract them from the larger area.
By Daft Logic on 25th March 2018
Is there a way to exlude small islands and perinnials in parking lots or other areas that are being measured?
On 23rd March 2018
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.
By Daft Logic on 6th March 2018
Names of Buildings/businesses on map inhibits area calculation.
ie: can't place a marker flag over printed names
By Kevbo on 6th March 2018
Which location are you viewing?
