Aerial Imagery in Africa
I am currently adding some data in north african villages and I've noticed that pretty much every one looks like this (maybe more clustered). These are obviously buildings, but I'm unsure if I should add all the structures surrounded by a wall as one area or if those are just a few distinct buildings.
Also is editing through aerial imagery generally good in these areas?
Thank you!
"Moore Method" for Algebraic Topology?
So I'm in high school but have had a big interest in university mathematics for a few years. I'm at a point where I have all the prereqs for algebraic topology and since I really like abstraction and rigor (I have studied category theory before), I decided to start Strom's "Modern Classical Homotopy Theory".
This book uses the "Moore Method", i.e. there are no proofs in the text and the reader is supposed to prove everything on his own. My question is, if this is generally a good method for self-study, or if I should read more conventional texts like Hatcher.
Thank you in advance!
