[Gdal-dev] OGR and ODGI: reprojection problem

[Markus Neteler]

Hi,

for a long time I am trying to convert/reproject the
VMAP0 to SHAPE/PostGIS/WGS84.

Today I have updated another time OGDI and compiled with:
 ./configure --with-proj --with-zlib --with-expat

This should use the external PROJ4 as far as I understand.
Still no hope:

ogr2ogr -t_srs +init=epsg:4326 -nlt LINESTRING coastl_eurnasia_wgs84.shp gltp:/vrf/grass0/warmerdam/v0eur/vmaplv0/eurnasia 'coastl at bnd(*)_line'
ERROR 6: Failed to initialize PROJ.4 with `+proj=longlat +ellps=GRS80 +datum=NAD83 +no_defs '.
unknown projection id
Failed to create coordinate transformation between the
following coordinate systems.  This may be because they
are not transformable, or because projection services
(PROJ.4 DLL/.so) could not be loaded.

But: I have recompiled PROJ4 with the NAD files:
ls /usr/local/share/proj/
alaska  epsg  FL    hawaii  nad27  nad.lst       null          prvi      stlrnc  TN  WO
conus   esri  GL27  MD      nad83  ntv1_can.dat  proj_def.dat  stgeorge  stpaul  WI  world

Trying the command line version of 'cs2cs':

cs2cs -v +proj=longlat +ellps=GRS80 +datum=NAD83 +no_defs +to +proj=longlat +ellps=WGS84
# ---- From Coordinate System ----
#Lat/long (Geodetic)
#
# +proj=longlat +ellps=GRS80 +datum=NAD83 +no_defs +towgs84=0,0,0
#--- following specified but NOT used
# +ellps=GRS80
# ---- To Coordinate System ----
#Lat/long (Geodetic)
#
# +proj=longlat +ellps=WGS84
10.0001E 10.0001N
10d0'0.36"E     10d0'0.36"N -0.000

It's at least doing something.

Checking with 'ldd' reports:

ldd /usr/local/bin/ogr2ogr | grep 'ogdi\|proj'
        libogdi31.so => /usr/local/lib/libogdi31.so (0x40367000)

        libexpat_ogdi31.so => /usr/local/lib/libexpat_ogdi31.so (0x40649000)

        libexpat_ogdi31.so => /usr/local/lib/libexpat_ogdi31.so (0x4005f000)

No indication that libproj.so is used (which is there as well).

Any ideas what could be wrong? I'm getting desperated now... :-)
