Based on my personal experience, I do not think it is always necessary for LandDAO to always come down to the location of the lands to do any physical confirmation because technology has taking over everything and anything can be confirmed by simply tracking the land location and using a local land surveyor from the community to get all the necessary information before the lands are tokenized.
No doubt technology has taken over everything, but there are still areas where we need physical examination in order for you to be sure of what you are buying, especially if the land is located in urban areas where most of the lands are not located on maps, and even when they are being surveyed, something you can't get the proper situation of the land adding to family history attached to ownership, which you can only confirm if you have someone directly connected to the place to confirm. Such miscalculations and misinformation if you rely totally on technology alone to determine the land to acquire and how secure the land is.
For someone who is buying lands from LandDAO you have every right to engage in physical verification and confirmation of your lands of you are not convinced with the use of GPS to track the location of the land. You also have the right to send a representative to confirm the lands on your behalf before involving your surveyor and legal representative to document it.
You have got nothing to fear before purchasing land from LandDAO because they have legal documents to all the lands they acquire.
