This does not produce correct values. When it runs the output is:
-5056134.11 5898037.45 -0.0
-5057005.89 5898228.79 -0.0
-5057306.14 5899149.81 -0.0
The window values in other maps in the LCC projection are these:
proj: 99
zone: 0
north: 414531.46530409
south: 349974.06580951
east: 1201003.03577829
west: 1126515.54469129
cols: 74487
rows: 64557
e-w resol: 1.00000659
n-s resol: 1.00000619
top: 0.5
bottom: -0.5
cols3: 74487
rows3: 64557
depths: 1
e-w resol3: 1.00000659
n-s resol3: 1.00000619
t-b resol: 1
What might I have done incorrectly to produce both negative x values and
values that are so different from that of other maps in the same region and
projection?
