I’m interested in Astrocartography because I have moved twice now directly on my Pluto/descendent line from several hundred miles away for my husband’s work. My Pluto is ruled by my dk and I think there is something to this. I also happened to move to my Rahu line during my Rahu dasa and my Neptune line during a very interesting time for me. Is there a good resource for this?
I've been doing a lot with astrocartography myself lately. You have to log in and borrow the book from internet archive, but it's free to sign up and borrow,

The beginning of the book I'm not such a fan of, but Part Two, page 100, goes through all the planets, their lines and combinations. I find this part quite useful.
It's also interesting to combine this with relocation chart, which is your birth info but changing the location to the city under consideration yet keeping the time zone and DST if any the same.
