Instructions
To use the area calculator tool:
- Zoom and pan the map to find the area of interest
- Click on the map to place a vertices for the polyline
- Click as many time as necessary to define the polyline
The area enclosed will them me output in square metres and square kilometers
You can click the [Delete Last Point] button if you make a mistake or click [Clear All] points to remove all points from the map and start again.
You can also reposition the markers after they have been placed on the map by dragging and dropping them.
Information
The area calculator tool allows you to find out the area that is enclosed inside a closed polyline overlaid on a map.
Benchmarks
A measurement of Lough Neagh in Northern Ireland. Lough Neagh is reported to have a surface area of 388 kmē [1] , so the reading of 380 823 442m² isn't far off.
Future Uses and Ideas
- Allow the user to change the colour of the polylines and area shading (including transparent)
- Allow the option to have more than one area on the map at the same time
- Option to show/hide markers
- Output the length of the perimeter
- Add a quick find option to zoom in to the region without much panning and zooming
- Add square feet output
Version History
- 2nd February 2010 - Added perimeter output in metres and kilometers
- 25th March 2008 - Draggable markers, ability to click inside polygon and output in acres added
- 26th June 2007 - Basic area calculation added
- 24th June 2007 - Page created

Many thanks. Just helped some farming contractors agree acreage.

Multiple colors and multiple marked areas with rotational abilities for the map would be a great thing, especially in the case of subdividing property.

Fantastic! You need google earth pro to be able to do this otherwise! Thank's for making the site, much appreciated!

Great tool. It has helped me a lot in determining a site area in Cyprus. The only problem with Cyprus is that you can only zoom into a certain extent and I am unable to get to some additional detail.
This is not a reflection on this software; just a limitation imposed on the satellite images.

Great work.
I am probably missing something as you seem to have done more than I can think of but is there a way to find the full UK postcodes within the shaded area?

This really is a fantastic tool - thank you so much for investing your time and effort to develop this.

Great tool. Looking forward to the proposed upgrades. Would like to see the ability to input longitude and latitude.
Thank you for a great internet tool.

I'll echo Frank from 9/9/09 above and would like to enter in a series of LatLongs from a KML file.

Brilliant. Working on a series of small relict forest patches in West Africa Google Earth was the first Godsend, your area tool was exactly what I was needing next.

Very great!
Is it possible to zoom (although lack of resolution), when google-map stops zooming. It will make marker positioning easier in very small area.
And it is quite accurate (considering the time spent clicking the market).
rgds,

Love the site but I'd love to see the zoom out button working if that's possible? maybe even add functionality to use the scroll wheel on my mouse?
Great site either way and will continue to use this for a long time to come...

Love the site - have been using googles planimeter for a while now but prefer this site as you can adjust the markers set if you get it wrong rather than having to start over each time....

THANK YOU! I knew the program was out there.

"Quote "very useful tool for mapping territories for sales use". This comment was probably by a Realtor."
Perhaps NOT a Realtor trying to stiff a surveyor. Outside sales personnel and managers may use area calculations to develop work assignments.

This is a great "tool". However, the comment made on 4/05/2009 scares me.
Quote "very useful tool for mapping territories for sales use". This comment was probably by a Realtor. Remember, you should always use a Licensed Surveyor (LS) to map and state the acreage.Unless you are a LS you are not qualified to state an acreage for a property that you determined using a "tool".

great tool - thanks! would it be possible to search for a place by name and/or postcode? instead of zooming in on the map
