[gdal-dev] WKT Interpretation Change

[Andrew Bell]

Hi,

I'm trying to figure out what rule changes have taken place that have
apparently invalidated my SRS.  I suppose that this was valid WKT1 but not
WKT2.  Can anyone provide some more detail?

Thanks,

With GDAL 2.4 I get the following:

(gdaltest) $ gdalsrsinfo
"PROJCS[\"unnamed\",GEOGCS[\"unknown\",DATUM[\"unknown\",SPHEROID[\"GRS
1980\",6378137,298.2572221010042,AUTHORITY[\"EPSG\",\"7019\"]]],PRIMEM[\"Greenwich\",0],UNIT[,0.0174532925199433]],PROJECTION[\"Transverse_Mercator\"],PARAMETER[\"latitude_of_origin\",24.333333333],PARAMETER[\"central_meridian\",-81],PARAMETER[\"scale_factor\",0.999941],PARAMETER[\"false_easting\",200000],PARAMETER[\"false_northing\",0],UNIT[\"US

                AUTHORITY["EPSG","7019"]]],

    PARAMETER["false_easting",200000],
    PARAMETER["false_northing",0],
    UNIT["US survey foot",0.3048006096012192,
        AUTHORITY["EPSG","9003"]]]

With GDAL 3.0 I get:

(gdal3) $ gdalsrsinfo
"PROJCS[\"unnamed\",GEOGCS[\"unknown\",DATUM[\"unknown\",SPHEROID[\"GRS
1980\",6378137,298.2572221010042,AUTHORITY[\"EPSG\",\"7019\"]]],PRIMEM[\"Greenwich\",0],UNIT[,0.0174532925199433]],PROJECTION[\"Transverse_Mercator\"],PARAMETER[\"latitude_of_origin\",24.333333333],PARAMETER[\"central_meridian\",-81],PARAMETER[\"scale_factor\",0.999941],PARAMETER[\"false_easting\",200000],PARAMETER[\"false_northing\",0],UNIT[\"US
