[Gdal-dev] prj string problem

[Gao, Peng]

I have a tiff image and gdalinfo returns the following prj string:

PROJCS["unnamed",
    GEOGCS["NAD83",
        DATUM["North_American_Datum_1983",
            SPHEROID["GRS 1980",6378137,298.2572221010002,
                AUTHORITY["EPSG","7019"]],
            AUTHORITY["EPSG","6269"]],
        PRIMEM["Greenwich",0],
        UNIT["degree",0.0174532925199433],
        AUTHORITY["EPSG","4269"]],
    UNIT["metre",1,
        AUTHORITY["EPSG","9001"]],
    AUTHORITY["EPSG","26986"]]


ESRI ArcGIS software does not accept the prj string. One reason could be
the PROJECTION parameter is missing from the PROJCS definition. According 
to the WKT spec at 
http://geoapi.sourceforge.net/snapshot/javadoc/org/opengis/referencing/doc-
files/WKT.html,

PROJECTION is not optional within a PROJCS. How should I fix this?

Thanks,
