Hi Klaus, This happens for certain areas when you zoom in. To switch the 45degrees view off, please use the drop down map at the top right of the map and untick the 45 degrees option.

Somebody ruined this site. Now when you zoom in it goes into perspective mode and you canīt measure a thing! Please fix it!

Christina, Please see this Capture

Hi there is no readout showing for the area below the map once i have marked the area.
By Christina on 30/07/2015
Hi Claudiu, thanks for the suggestion. We will look in to this.
By Daft Logic on 28/07/2015
Hi Crystal, the [Create New Area] button below the map should draw new areas. Are you using this? When you you say Save what do you mean? Thanks.
By Daft Logic on 28/07/2015
Can I save multiple areas? It appears to only save one area at a time. I'm trying to add up dozens of areas.
By Crystal on 28/07/2015
For the future, an interesting option should be able to select different versions of the maps. Ex. For a certain area there is a new map (2015), but very blurred, taken from high altitude. In Google Earth I found a version of the map from 2011 with many details for the same area.
By Claudiu on 28/07/2015
This is great! It helped me out so much thank you!

Hi Reginaldo, you could use the Toggle Markers button to hide them.
By Daft Logic on 20/07/2015
It's more and more useful, but for small areas the markers cover the shapes. What about reducing them ou making them transparent a little?
By Reginaldo Bosco Gomes on 19/07/2015
I can see no measurement dims. so how do I know if area is same as on my plot map?

Fantastic for farmers to measure odd shaped paddocks (Australia) Love it!
By David on 07/07/2015
J.N. nothing has changed recently. Is it still not working? Could you try a different wen browser?
By Daft Logic on 06/07/2015
have used this site before and worked great. now I can't open a map. what's problem
By J.N. on 06/07/2015
No directions. Difficult to work with. If you have all day to figure it out and play with it. Easy to work with the map. Now if they can just make it easy to measure the area, they will be in great shape and very do-able.

Hi Rich, you could use the print screen option of the Windows snipping tool or equivalent.
By Daft Logic on 30/06/2015
Is there a way to print the image of the area I have created?
