Hi,
I have a GRASS location using Lambert Conformal Conic projection.

g.region -p
projection: 99 (Lambert Conformal Conic)
zone: 0
datum: wgs84
ellipsoid: wgs84
north: 2000000
south: -3135000
west: -2200000
east: 3352000
nsres: 1000
ewres: 1000
rows: 5135
cols: 5552
cells: 28509520

cat PERMANENT/PROJ_INFO
name: Lambert Conformal Conic
proj: lcc
datum: wgs84
ellps: wgs84
lat_1: 0
lat_2: 0
lat_0: 42.5
lon_0: 0
x_0: 0
y_0: 0
no_defs: defined

I get the following errors when I try to use v.proj or r.proj to reproject any vector or raster to or from this location.
WARNING: Unable to initialise PROJ.4 with the following parameter list:
+proj=lcc +lat_1=0 +lat_2=0 +lat_0=42.5 +lon_0=0 +x_0=0 +y_0=0
+no_defs +a=6378137 +rf=298.257223563 +towgs84=0.000,0.000,0.000
WARNING: The error message: conic lat_1 = -lat_2
ERROR: Unable to get projection key values of input map

I would appreciate any help resolving this issue. Thanks,

Try including values for Lat_1 and Lat_2
