I am unable to get the InstallImagePlugin to work in JOSM GOAL ====
I have an image of a map that I scanned and I want to load it into JOSM as an underlay so I can trace the ways on the map in JOSM. PREPARATION ============ The map file is called map.jpg and I have created a world file called map.wld TRIALS ====== I don't fully understand the values I need for the world file, however it represents an area approximately 8 kilometres (West to East) by 6 kilometres (North to South) and the top left hand edge of the map is approximately at a latitude of 1.5 (North) and a longitude of 103.5 (East) so I looked at this link: http://en.wikipedia.org/wiki/World_file and my file contains these values as a starting point: 100.0 0.0 0.0 -100.0 103.5 1.5 When I load the image, the plugin notices that I don't have a projection file (.prj) so it asks me if I want the default coordinate system. I choose Yes. Nothing appears and the scale (top left corner of JOSM goes to 20037.5 and I cannot zoom in or out. I have varied the values in the world file considerably but with the same result. QUESTIONS ========== Has anyone used this plugin? Can you give me reasonably correct values for my world file? Do I need to create a projection file What do I need to do to make this work?
