Never mind, I got it to work again.

Awesome tool. I have been using this for years. However, we seem to have lost the ability to swivel the view on four sides in the satellite view. For measuring landscape square footage that was critical in determining what is located on all sides of a building, if shadows obscured one view, etc. What can we do to get that back? Is a pay option available?
By JH on 21st November 2023
Can you describe the lat/long datums allowed and the format for coordinate entry? Thank-you
On 1st November 2023
Bravi! Bravissimi! Adesso si memorizzano anche le frequenti località! Bravi! Ciao a tutti!
By Paolo. Milano. on 18th August 2023
Yes, we are still active.
By Daft Logic on 28th January 2023
Hope all is well. But is this site still active?

Worked great to map out the coverage of my off roading group, only 25,000 square miles! Thanks!
By Astrid on 26th January 2023
when measured on this site. the site crashes. i think after a few plotting points the system crashes.

How accurate is the acreage estimation? I use this daily to get a rough idea of fencing and pasture acreage

Hi Neo, that can be done on this page : Distance Calculator.
By Daft Logic on 15th June 2022
Super useful, It would be nice to have the distances between points.
By Neo on 14th June 2022
Add a option to print the selected Area along with details as PDF
On 17th March 2022
Briliant tool!
On 28th February 2022
Great tool thank you! Very useful to draw areas around cities to see how big and/or dense they really are. Only feature I would request is the ability to move a selected area around. It'd be useful to able draw an area around one city and move or duplicate that selection on top of another city so I can compare their shape and size in a quick and visual way.

Thank you, this tool aided a law engineer in Mexico, to save an area of 18.54 acres of city forest
By JOSE EDUARDO PEÑA GONZALEZ on 28th December 2021
A very helpful tool
On 26th September 2021
Is there an API for this calculator that we can use?
By Ray on 20th July 2021
great tool thank you
On 19th July 2021
Thanks for Such nice Software.
I love your work
By Shahzaib Rasool on 22nd June 2021
Hi, no, the code is not open source.
By Daft Logic on 14th June 2021
is this code opensource? Can we get this tool's code? please provide code and more references. Thanks
On 14th June 2021
Thank you.

Hi I am in need for a tool that i can draw on and given a log, lat i want it to return if the location is inside my drawing or not. Can i use this tool to do it? or any other suggestion?
By Mithu on 25th April 2021
update please
On 20th April 2021
would love the option to change area colors when adding a new area for example area 1 outline and fill color be different then area 2 fill color and outline
By Toro Blacktop & Concrete on 18th April 2021
Johnnie, thanks for the feedback. There is no straightforward way to do this. The only option is to reset back to an empty map then load the one or more required areas. We will add this in to the Future Uses and Ideas list.

By Daft Logic on 25th March 2021
What a fabulous tool! I use it all the time. Thank you! Is there a way to turn on multiple saved areas at a time without the areas merging into one?
By Johnnie on 23rd March 2021
Amazing tool! Thanks!
By Lucas Eugenio on 22nd February 2021
I understand the purpose and the need for ads for your site, but is there a way to move the ad between the map and the data for the measured area? I need to be able to take snips showing both the map and the data together, but the ad is the only thing that can be seen.
By Shawn on 19th January 2021
GJ, if you wish to measure length, please try Google Maps Distance Calculator.
