I have built and maintain a SWTOR game map atlas. At the moment, it's all static jpg maps, but I would like to get the info into an actual GIS software to get more functionality and make my website more mobile-friendly.
I assume the first step is to get the game map into a GIS software. I have a png of the map, and I have game map coordinates for a few points on that map. I used the QGIS georeferencer plugin; however, no matter which projection I choose (I tried UTM 19N, UTM 1N, custom eqc I found in this post, even EPSG 2046), my map always shows upside down and/or inverted left-right.
I've read around the internet quite a bit, but still don't understand what I'm doing wrong.
What projection should I be using? Is there a way to define a custom projection and control which axis is pointing upwards (I tried +axis=end without luck)?
