The birds eye view will also work when it is available. Please bare in mind that the points are placed at ground level, even if an object sits in front of the ground.

Does this also work when using the "Bird's Eye View" rather than the straight down satellite view?
Una Herramienta Realmente útil!

Ótima ferramenta. Como sugestão a página poderia permitir o download do perímetro gerado em kml ou kmz. Obrigado.

Nice tools but the perimeter in a 2 point line should be just the length of the line not twice as it is now.
