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.By Jason Kreski on 22nd January 2022
Thank you, this tool aided a law engineer in Mexico, to save an area of 18.54 acres of city forestBy JOSE EDUARDO PEÑA GONZALEZ on 28th December 2021

is this code opensource? Can we get this tool's code? please provide code and more references. ThanksOn 14th June 2021

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 pleaseOn 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 outlineBy 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.By Daft Logic on 20th December 2020
Can you indicate the length of each line/side of an area?
Great tool you built there, man!By GJ on 20th December 2020
Very useful tool for me. A little suggestion if the outline of each area can use a different color, so that adjacent areas can be seen clearly if they overlap.By Akai on 30th November 2020
I was asked to calculate volume of a particular airspace of particular area, and instead of dealing with irregular polygon, this website saved me plenty of time,
