A couple of questions and comparisons.
Wow, nice work! I love the graphical representation. I appreciate the effort you put into this. Except, I am unlclear as to how you came up with some of the numbers.
You have the northern most coordinates being: -62.73, -32.88 (x and y)
You have western most coordinates being: 150.94, -152.79
My coordinates show northern most should be: 50.92, -330
My coordinates show the western most should be : 145.79, -145.21
Projecting those coordinates, I get 145.79, -330 for the NW corner of my bitmap. You have -150.94, -32.88 I can see you may have added a little to the western coordinate, but what about the northern coordinate? A miss placed decimal point?
Even if I Negate the western and eastern coordinates (-W,N,-E,S) like tonyis3l33t's post says, I do not come up with the same numbers as you. I get -145.79, -330 for the NW corner of the bitmap.
You have the eastern most coordinates being: -132.86, -100
You have the southern most coordinates being: 52, -329.81
My coordinates for eastern most are: -130.82, -100.90
My coordinates for southern most are: -113.52, -45.44
Projecting those coordinates I get: -130.82, -45.44 for the SE corner of my bitmap. You have -132.86, -329.81 Again, I can see your eastern coordinate being close, but the southern coordiante is no where near what I have.
Now, if I negate the E/W coordinate, I get 130.82, -45.44 for that SE corner of the bitmap.
Futher, I tried the zone Erect from your post and it doesnt work. My cursor moves backwards, even though I am moving forward and does not follow the map.
How do I get the BM coordinates? You have 12,5 for NW corner and 421, 433 for SE corner of bitmap. I need to have those to get the zone erect. Or I need the zone erect to get the map image location on the bitmap.
This is the Zone Erect that I get from using Open Office with the map.svg file: -150.94, -329.81, 132.86, -32.88 which is wrong, we know because the coordinates from /loc did not reach the extremities.
Northern most coordinates: 50.92, -59.95, -330.06
Southern most coordinates: -113.52, -70.38, -45.44
Eastern most coordinates: -130.82, -68.21, -100.90
Western most coordinates: 145.79, -63.39, -145.21
I think I almost have this figured out, if you could explain how you got those number. Thanks so much for you work on this and your effort to help me understand this.
