Excellent algorithm. Is the maths behind complex? Now I know what an acre looks like relative to how many properties you can build on it. About 13, 5 bed semis on 311sqm plots! An acre is much bigger than I thought.

Great.

Its a very great toll for area calculatorr

It is good. but it would be better if a mobile app will develop.

This large land area is owned by 3 Brothers. Whom I have met and who are all very keen to go forward with a solar farm. I've explained that we may only be able to use one 25 acre section of the land. Highgate Lane which runs along the South of the Land has a 33kV Substation which is only 500m from the bottom South West corner. You will also be able to make out the 11kV 3phase power lines going across the land.

Mighty handy

From a ranching aspect this is a neat tool. I brought it up and figured how much hay we have cut and what is left. I'm by no means a tech wizzer and I got through it. Thanks you.

Hi, Unfortunately you cannot import a KML.

Can I import a KML file to work with
By les on 06/07/2014
I see. Thanks for explanation!
By Tautvydas on 06/07/2014
very good

Tautvydas this is an area calculator not a distance calculator. What are are reading is the perimeter, which for a 2 sided area is twice the distance between the 2 points.
By Daft Logic on 04/07/2014
The distance in this map and google map is two times bigger. This tool is very inaccurate. For example, Budapest, Andrassy street. Here the tool says it is 4659 meters. Google maps, though, tells me it is just 2300 m.
By Tautvydas on 04/07/2014
Excellent tool! Thanks and congratulations Daft Logic. Although it would be cumbersome for irregular shapes with multiple points, I think that an added option to get the length of each side of the polygon would be a nice plus. Also for multiple areas, it'd be great to see all areas details, not just the last one and the total.
By Jose G on 01/07/2014
Awesome,thanks.
By chattwolf on 30/06/2014
chattwolf, this functionality has now been added.
By Daft Logic on 29/06/2014
Fantastic tool,is there any way of changing the colour shade from green to another?.
By chattwolf on 28/06/2014
Awesome program. My husband does custom field work for local farmers and it's nice to be able to get an accurate measurement and not just rely on the farmers memory.
By PJ Neumann on 28/06/2014
Hi, is this Google updated one? because can't see any update things in my location . thanks
By Daminda - NZ on 28/06/2014
Brilliant!!

Great tool. Is there a way that the satellite map can show section lines, or show latitude and longitude for a specific point.
By Dave on 25/06/2014
Hi, if you switch to full screen, the print out should be better.
By Daft Logic on 24/06/2014
How can the modified map be printed without splitting the page due to the header info above the map ?? How can it be done on Mac
On 23/06/2014
My problem previously was that there was a "45 degree" box that was tilting the view. I could not uncheck it. Then I did some things (?) that allowed me to uncheck it. That enables a proper 2-D area measurement.
By smithpd on 20/06/2014
I like your tool, but I have two problems. 1) When I zoom in to an area the view becomes rotated, looking down not vertically but at an angle. I can't enter points that are hidden behind a building. If I enter some points in one view and then rotate the view, the area is floating in space, not in the original position, so additional points are not valid. 2) I would like to be able to toggle markers off. I can't enter a point behind a marker.

On 12/06/2014, you need to create an account. Then once logged in, you can save and load areas you have drawn.

How does one save their work?
