[PROJ] conversion from northing-easing system

[Javier Jimenez Shaw]

Hi

The system EPSG:31467 is defined in the db as northing easing.
But I get strange results if I use WKT1 on cs2cs

echo 50 8 | cs2cs EPSG:4326 EPSG:31467
5540885.81 3428379.33 0.00

echo 50 8 | cs2cs EPSG:4326 "$(projinfo EPSG:31467 -o WKT1_GDAL
--single-line -q)"
3428379.33 5540885.81 0.00


exporting as WKT2 we see that the axis order was lost:

projinfo "$(projinfo EPSG:31467 -o WKT1_GDAL --single-line -q)"
PROJ.4 string:
+proj=tmerc +lat_0=0 +lon_0=9 +k=1 +x_0=3500000 +y_0=0 +ellps=bessel

WKT2:2019 string:

        PARAMETER["False northing",0,
            LENGTHUNIT["metre",1],

    CS[Cartesian,2],
        AXIS["(E)",east,
            ORDER[1],
            LENGTHUNIT["metre",1]],
        AXIS["(N)",north,
            ORDER[2],
            LENGTHUNIT["metre",1]],
    ID["EPSG",31467]]

Is that normal?
