So I just read through the whole guide (skimming some of it when I recognized concepts) and I'm very surprised to see that mapping in GIS is very similar to mapping in any other vector based software designed for maps or not. Very cool. I use qgis for simvis work, placing features and its data for rendering in industry image generators such as Genesis RTX by Diamond Visionics. I also use it to convert, compress, and align satellite imagery and elevation data with features or vice versa. I'd like to see if some of these concepts could be applied to make amazing visualizations of fantasy worlds. Would require realistic elevation data with erosion calculations and a way to create geotypical terrain imagery, but I think this would be an amazing crossover.
