Best drone for archaeological/architectural/cultural survey?

[yusaku]

Hello,
I am gonna buy my first drone for my archaeological/architectural/cultural projects.
My budget will be around 2000$ but maybe could manage to rise it up to 4000$ (including extras like batteries/bags etc).
My current project, and the reason I am buying the drone, is a series of really small abandoned settlement sites (around 1 acre each) in a windy island.
Apart from this I intent in using it for documenting/measuring archaeological sites.

Thank you
Kostas
