Hello,

In your first attempt, you just made a typo. You wrote 

	+proj=llc 

but it should be 

	+proj=lcc


In your second attempt, 9801 is not an EPSG code for a 
particular coordinate reference system.  Rather, 9801 is
the EPSG code for the class of Lambert Conformal Conic projections
with one standard parallel.  
   I cannot find an EPSG coordinate reference system that matches 
your proj4 definition, but I may have missed it. 

Best regards,

Subject: [FWTools] gdal_translate for Lambert Conformal Conical

Hello,

I'm trying to create a geotiff file from PNG map file which uses Lambert Conformal Conical coordinate system, and hitting a road block.

$ gdal_translate -of GTiff -co INTERLEAVE=PIXEL -a_ullr 41.5569
-121.9248 32.9250 -112.9434 -a_srs '+proj=llc +lon0=90w +lat_0=25n
+lat_1=25n' test.png dest.tif
Failed to process SRS definition: +proj=llc +lon0=90w +lat_0=25n
+lat_1=25n

$ gdal_translate -of GTiff -co INTERLEAVE=PIXEL -a_ullr 41.5569
-121.9248 32.9250 -112.9434 -a_srs EPSG:9801 test.png dest.tif ERROR 6: EPSG PCS/GCS code 9801 not found in EPSG support files.  Is this a valid EPSG coordinate system?
Failed to process SRS definition: EPSG:9801

Any idea what I am missing?

I downloaded gdal as part of FWTools package http://fwtools.maptools.org/

Thanks in advance,
-Gen
