Hi Tim, unfortunately this is not possible.
By Daft Logic on 25/05/2015
Is there a way to rotate the entire map?
By Tim on 25/05/2015
Hi htslnk, it isn't that smart. It will assume there is a flat surface.
By Daft Logic on 25/05/2015
Great tool! Does anyone know if this takes the changes in the altitude into account when calcualting the area,or makes the calculation as if it is a flat surface?
By htslnk on 25/05/2015
Very cool, thanks :)

Hi Manchixxx, was the roof at an angle? This top down view will not be the same as the area of a slanted roof.
By Free Map Tools on 11/05/2015
This not exactly, because I did a roof measure and compared with this map the measure was very different.
By Manchixxx on 11/05/2015
Hi, we have just made a small update that will display the location (lat/lng) when you hover over a marker.
By Daft Logic on 11/05/2015
Is it possible to get the coordinates of the points that make up the polygon?
On 11/05/2015
great tool... can anybody tell what is the accuracy level of the area calculated by this tool
On 11/05/2015
Hi vibaby, unfortunately this is not possible.
By Daft Logic on 10/05/2015
How can I go back to an earlier drawn area to see its area?
By vibaby on 10/05/2015
du moment que cet outil est disponible pour justifier les superficies il est nécéssaire de le prendre en charge comme point fort crédible pour résoudre les affaires contentieuses , merci .
By ossoukine on 09/05/2015
This is great tool and helped in rural area to calculate the raw area.
By PREM BISHNOI on 09/05/2015
This is a great tool. I use it several times a week. It would be great if I were able to zoom in one step closer. It seems as if this capability is available on G-Maps.
