I'm completely new to all this so bear with me. In order to generate a model from a .osm file I am following the instructions at this link. However I'm stuck at the 'Add a map layer with satellite imagery' section. I have saved a .jpg file from Google Earth but from here I don't know how to go about sourcing a .jpw world file for that .jpg image.
On a scale of one to ten I probably know zero about GIS, I wanted to use this tool to create a quick city model but I'm feeling maybe I'm out of my depth with this tool.
Any feedback would be much appreciated.
