Before the update....all photos were in the winter, with no leaves. Now I get see anything because of the trees in the photos.
Good job all. Very useful

Hi, can you see the "Output : Current Area"?
By Daft Logic on 30/01/2016
When I define area, only give me the perimeter and not the hectares. How do

Hi, when you click Generate KML do you see the option [Download KML File Here] appear just below?
By Daft Logic on 28/01/2016
Great website, but download kml does not work with Firefox
Craig, thanks for the comments. We have just added some keyboard shortcuts, see the Keyboard Shortcuts heading for more information. There have been a few changes to try and improve the page layout and usability. For printing, I suggest doing it via Full Screen mode.
By Daft Logic on 28/01/2016
Fantastic program, I have been trying to find this type of program for our farming acreage for years, thank you. Are there any "hot keys" or function commands I can use while in full screen mode? Specifically to toggle on and off, to start a new area and see the acreage in area. Also it seems the map screen is either a tiny window or full screen (I have used the med, and large) is there a way to stretch the the window or put the acreage and commands to the side and locked so I don't have to scroll all around. Finally, how do I shrink the "area" which the program thinks I am viewing. When I print the information, it comes up with 3 pages of map but I only need one of them. I realize I can tell it to print only 1 of 3 or 4 pages from the print command in chrome. I have not found any print command on the page its self..

Hi, it is not possible to upload a KML file.
By Daft Logic on 21/01/2016
how do you upload your own kml file and compute areas in it?
Hi, It should be possible to do what you say. If a new function to upload/import a KML to this page was added would this help? Please send a sample KML file from your GPS and we will look in to this. A contact email can be found here.

I am attempting to use the Area Calculator with my Raven Cruizer 2 GPS. I can create a KML file with the GPS. and save it to a jump drive. Is there a way to transfer the file, or combine it with a KML file created here? I really like this set up and use it regularly to measure agriculture areas. Thanks for making this tool available.
Hi M, thanks for the feedback. Just to check ... can you see the and - to zoom in and out at the bottom right of the map? I have added the color scheme suggestion to the Further Uses and Ideas list.
By Daft Logic on 11/01/2016
Thank you so much for this website. Have used it daily for over a year. As far as the update with the interface, can you please add the zoom in and out features for the area calculator. Also, in the future, would it be possible to allow different color schemes for additional output areas rather than just one. If that is possible, toggling between multiple areas would be fantastic. Thank you!

Hi Brandon, thanks for getting in contact. Please try the text box below the map beside "Add a location manually". This should add a marker at the loction.
By Daft Logic on 07/01/2016
I'm on Google Chrome, and ever since the update with the new interface, an address marker does not appear on the building when the location comes up. Previously, when I typed in the address, the pin would fall right on the building. Now it's gone?

Otimo sistema para medir area atraves dos mapas.

May i have code for this .. please Thank you,

Hi PK, thanks for the feedback and the detailed descriptions. The bug with Total Area should now be resolved. The height of the map should now size depending on the screen size viewing it. The end result is a large desktop screen should now have a taller map, yet mobile/tablet screens will not be as tall.
By Daft Logic on 31/12/2015
When you first access the page and enter multiple areas it will display the total area measurement. But if you make a mistake and "clear all points" followed by the re-entering of your multiple areas, it no longer displays the total area measurements. The only way to get around this is to refresh the page and start over. Also, on my desktop the viewing window for the map is so narrow top to bottom, more so than the old look. It would be nice if this was longer or adjustable.
By PK on 30/12/2015
Hi Jim, Thanks for the feedback. The total area should be displayed below the map once the 2nd area has been drawn. Please see this screenshot ... http://postimg.org/image/ka542uyj7/ Let us know if it doesn't appear for you...
By Daft Logic on 26/12/2015
Hello, This is an awesome tool!!! What happened to the total acres when calculating multiple areas? I can no longer find it. That's is a very important feature v/r Jim
Thanks for the feedback. The purpose of the change is to ensure the page displays correctly on mobile and tablet devices. We will endeavour to address any issues that are deemed to be a step backwards. Can you confirm what the error is when to try to log in? Does it not recognise the username/password?
By Daft Logic on 24/12/2015
What was wrong with the old Daft Logic.? This one is too complicated and I can't even log in to use it. You guys at Google ruined a real good tool!
Great tool. Prefer the old display though. I liked being able to measure and check the area without having to scroll down the page. It would be nice to have the outputs next to the map
Amazing Job. Tool is great, but what has to be really commended is the simple intuitive controls to fix the area.

Hi Moe, when this happens you can revert back to the plain 2d view by clicking on the icon with four squares found at the bottom left of the map.
By Daft Logic on 21/12/2015
It appears that the image has now become more 3D than it was before, its now more of an angled overhead view instead of a 90 degree satellite image. Can this be toggled?
By Moe on 21/12/2015
THIS IS JUST AN AMAZINGLY USEFUL TOOL.ALL RESPECTS TO ITS DEVELOPPERS
