Mapping lands & properties accurately

Hello,

As woodland owner I would like to know if the app lets you map / pint point accurately the limits of a property.

My idea is to walk through the limits of the property and at same time the app draw that area in the map. Later I should be able to calculate size of property and export it to google earth for example.

Also, in case the above is possible, can I correct or fix live the path in case i didn’t walk correctly thought the limit?

Can you tell me if the app lets you do that?

Many thanks in advance.
