Porque ao passar email, o email vai mas não aparece nada, não envia o conteúdo? O que fazer para enviar corretamente?

Hi, the area calculator is not used for measuring distance between points. It does have a perimeter output which is twice the distance between 2 points when there are 2 points
By Daft Logic on 15/04/2014
Great tool - I believe that the measurement of a line is "doubled" in the "current perimeter" calculation. For example, measuring a tennis court provides the correct area and perimeter, however if I measure the length (should measure about 78 ft, the resulting measurement is about 156.

Is it possible to access winter map? Tree cover is a problem.

Great tool for what I need to do. However, when printing, it's not what I see on the screen and I have to align polygon to upper left of screen to print. Also it splits pictures on printout. Would be nice to have a print button to add a title and to print map and measurements on single page (portrait or landscape).

Hi, can you provide some examples of the inaccuracy please?
By Daft Logic on 22/03/2014
I think it's not entirely accurate. I tried it on some soccer fields, and it's way off.
