I'm using GDALOpen() to read an ArcInfo binary grid file (a directory of
.adf files). The projection is presumably specified in the file "prj.adf",
which contains the following:
Projection LAMBERT
Zunits NO
Units METERS
Spheroid CLARKE1866
Xshift 0.0000000000
Yshift 0.0000000000
Parameters
9 56 0.000 /* 1st standard parallel
11 0 0.000 /* 2nd standard parallel
-84 20 0.000 /* central meridian
10 28 0.000 /* latitude of projection's origin
500000.00000 /* false easting (meters)
271820.52200 /* false northing (meters)
The dataset opens successfully and allows me to read the grid values, but
when i call GetProjectionRef(), it gives me the following string:
"LOCAL_CS["LAMBERT",UNIT["METERS",1]]"
This seems quite wrong; it's picking up the Lambert but missing the rest of
the projection description.
This is with GDAL 1.1.8 (not from CVS). Am i doing something wrong or is
this an issue with GDAL?
Thanks,
Ben
