Brilliant stuff - cheers!
By Richard Harnwell on 18/12/2008 Great tool, i had imagined some smart people would come up with it soon or later. Grats!
By Lorenzo on 16/12/2008 Nancy, at the moment you can only find it by using a conversion tool from elsewhere. This is a function I will add to the to-do list (show area in acres as well).
By Daft Logic on 08/12/2008 A very useful tool. Being able to save the zoom level and data points (perhaps via a bookmarked URL) would be a fantastic addition.
By Lawrence Hudson on 08/12/2008 I have found my area and have pin pointed it. How do I get the measuremet to convert to acreage.
By Nancy on 08/12/2008 Very good. I would like to be able to drag the selected area, to gain an idea of the size in relation to other areas on the map. (i.e. take a snapshot of France and see how big it is compared to Canada etc).
By Hayden on 03/12/2008 can i copy the image.
On 29/09/2008 Very nice. Is there a way to get the area calculation to show in acres rather than square meters?
By Marc Suffern on 28/09/2008 I was able to get around not being able to click inside the area. All you need to do is click outside and drag the point in. It works fine that way. Helpful tool. Thanks for building it.
On 20/09/2008 It would be nice to do irregular shapes, such as if you could exclude an area in the middle of the area to be measured, or have an irregular shape that encroaches on the area to be measured.
On 11/09/2008 Nice tool. Would it be possible to turn this into a tool that could be shared via Google's My Maps (content created by others)?
By Joe on 18/07/2008 Neat!
By Daniel on 28/05/2008 Great tool, thanks, would i able to search for a specific address to do the calculation?
On 28/05/2008 Very sweet! Good job. I own some land in Central Maine and divying up parcels without having to go through a GIS/survey service for "what if's" is a godsend. One nice-to-have would be a pulldown for area units (acres, in my case) Thanks!!
On 06/05/2008 Trying to do this same thing for work-- excellent job, I know how challenging this algorithm can be!
By Dan on 02/04/2008 Thanks for creating this. Very helpful when trying to figure out acreage. Google maps should have this tool built in!
On 11/03/2008 Absolutely fantastic!!
By Mark Taylor on 10/03/2008 This Rocks, cheers, fantastic tool
