To be sure, that's this one, right? http://www.remotesensing.org/geotiff/proj_list/lambert_conic_conformal_2sp.html > I have noticed that if I am selecting the projection parameters through the > Grass GUI dialog, and lat_0 = lat_1, the value of lat_2 doesn't seem to be > included in the projection definition (see attached screenshot > lat_2_is_gone.png). Strange. I have replicated it here and it looks fine: GRASS 7.0.3 (lcc):~ > g.proj -w PROJCS["Lambert Conformal Conic", GEOGCS["wgs84", DATUM["WGS_1984", SPHEROID["WGS_1984",6378137,298.257223563], TOWGS84[0.000,0.000,0.000]], PRIMEM["Greenwich",0], UNIT["degree",0.0174532925199433]], PROJECTION["Lambert_Conformal_Conic_2SP"], PARAMETER["standard_parallel_1",65], PARAMETER["standard_parallel_2",75], PARAMETER["latitude_of_origin",60], PARAMETER["central_meridian",60], PARAMETER["false_easting",0], PARAMETER["false_northing",0], UNIT["Meter",1]] > If however, lat_0 != lat_1, lat_2 *does* get included in the projection > parameters (see attached lat_2_exists.png). > > Is this an error? Or is it incorrect usage on my part to have lat_0 and > lat_1 equal? Which GRASS GIS version do you use?
