classic maps blender import

[decomon]

hi there, im trying to do an art project and i want to know if there is any way of port the maps into blender, like the terrain , trees , dont know how much of it can be ported if anything at all, is there some kind of workflow or plugin? ive been looking around and from what i can gather, most of the blender and import talk is about the 3d models of characters and objects ,but im looking for whole maps instead , thank you for reading!
