A soldier would look for defensibility and points of attack A hydrologist would look at water flow. A botanist would analyze plants. . . .
A land-holding lady, especially since her lands are heavily agricultural, ought to look at whether this land could be settled, and wonder why not, at what monsters or magics it might hold to hinder that. (In settled lands, she should be able to judge how productive they were, and whether they were farmed well.
Except that the heroine was not raised for her current status. She was not educated to that eye. Then, she knows it. So should she be wondering whether it really is good farm land or whether, if she had been properly taught as the heir, she would see at a glance that something was wrong with it all.
All of which is only characterization since she is not dealing with that side of her post at all, at the moment. . . sigh
