Hi all,

I am having problems with the Lambert Conformal Conic projection.

I am trying to convert an LCC file into UTM:

gdalwarp -of GTiff -s_srs '+proj=lcc +lat_1=0 +lat_2=0 +lat_0=50  +lon_0=0
+x_0=0 +y_0=0 +units=m +no_defs' -t_srs '+proj=UTM +zone=18 +units=m
+datum=NAD83 +no_defs' cols.asc cols.tif

I got the parameters from an existing LCC file.

Problem is, when I try to set this projection to my file I get an error
about the projection parameters.
ERROR 6: Failed to initialize PROJ.4 with `+proj=lcc +lat_1=0 +lat_2=0
+lat_0=50 +lon_0=0 +x_0=0 +y_0=0 +ellps=WGS84 +units=m +no_defs '.
conic lat_1 = -lat_2

Thank you in advance for any suggestions.

Matt.
