Hm, so maybe that value is correct. 1/0.000854993160055 is 1169.59999999961637120000, which would mean its about 1px per km.
I think I found an issue even before I warp: gdal_translate -of gtiff -CO TFW=YES -a_ullr -115 56 -105 54 -a_srs "+proj=lcc +lat_0=56 +lon_0=-115 +lat_2=49.33 +lat_1=54.66 +x_0=0 +y_0=0 +datum=NAD27" n.tif nn.tif Upper Left (-115.0000000, 56.0000000) (115d 0'6.63"W, 56d 0'1.81"N) Lower Left (-115.0000000, 54.0000000) (115d 0'6.63"W, 56d 0'1.74"N) Upper Right (-105.0000000, 56.0000000) (115d 0'6.05"W, 56d 0'1.81"N) Lower Right (-105.0000000, 54.0000000) (115d 0'6.05"W, 56d 0'1.74"N) Center (-110.0000000, 55.0000000) (115d 0'6.34"W, 56d 0'1.78"N) Apparently a_ullr isn't setting it correctly...
