I have some questions about the data you provide.
I would like to know how specific the road and railroad layer is, and whether I can edit the data and put some data on it or not.
Is it possible to see the sample picture of Hanoi?
Also, the price is a little too expensive for us. Our lab stated this year, so we don't have much research funds.
The data you sell is including to all over the world? If so, I would like to get the only data of Hanoi and around there, so please could I get a discount?
