[Gdal-dev] ERROR 6: Failed to initialize PROJ.4 with ...

[Helmut Kudrnovsky]

hi,

i've tried to warp a geotiff with the following command by the mean of gdal of the FWtools1.3.4 on a win-xp-machine:

C:\data_rev\rect>gdalwarp -of GTiff -s_srs Austria_GK_MGI_M31.prj -t_srs dhdn_zone3.prj teil2_gw_gk31.tif teil2_gw_dhdnz3.tif

where Austria_GK_MGI_M31.prj is:

PROJCS["Austria_MGI_M31",GEOGCS["GCS_MGI",DATUM["D_MGI",SPHEROID["Bessel_1841",6377397.155,299.1528128],TOWGS84[577.326,90.129,463.919,5.137,1.474,5.297,2.4232]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],PROJECTION["Transverse_Mercator"],PARAMETER["False_Easting",0.0],PARAMETER["False_Northing",-5000000.0],PARAMETER["Central_Meridian",13.33333333333333],PARAMETER["Scale_Factor",1.0],PARAMETER["Latitude_Of_Origin",0.0],UNIT["Meter",1.0]]

and dhdn_zone3.prj is :

PROJCS["DHDN_3_Degree_Gauss_Zone_3",GEOGCS["GCS_Deutsches_Hauptdreiecksnetz",DATUM["D_Deutsches_Hauptdreiecksnetz",SPHEROID["Bessel_1841",6377397.155,299.1528128],TOWGS84[598.1,73.7,418.2,0.202,0.045,-2.455,6.7]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],PROJECTION["Gauss_Kruger"],PARAMETER["False_Easting",3500000.0],PARAMETER["False_Northing",0.0],PARAMETER["Central_Meridian",9.0],PARAMETER["Scale_Factor",1.0],PARAMETER["Latitude_Of_Origin",0.0],UNIT["Meter",1.0]]

and the following error message comes up:

ERROR 6: Failed to initialize PROJ.4 with `+ellps=bessel +towgs84=598.1,73.7,418.2,0.202,0.045,-2.455,6.7 +units=m +no_defs '.
Creating output file that is 3643P x 3885L.

ERROR 6: Failed to initialize PROJ.4 with `+ellps=bessel +towgs84=598.1,73.7,418.2,0.202,0.045,-2.455,6.7 +units=m +no_defs '.
:0...10...20...30...40...50...60...70...80...90...100 - done.

what does this error message "ERROR 6: Failed to initialize PROJ.4..." mean?  i've got the TOWGS84 parameters for source (epsg-code: 1618, MGI to WGS 84-3) and target (epsg-code: 1777, DHDN to WGS 84-2)  from the epsg-database

best regards an thanks in advance
