Hi,
Our layer is defined in a local CRS like 31285.
Also the TOWGS84 parameter is set for correct placement of data in CRS
4326 (WGS84).
Now the placement in 4326 is correct and false in 31286, if I skip the
TOWGS84 parameter i have the vice versa effect.
Is there a way that the TOWGS84 transformation is only used when it is
needed?
Here our layer/projection section:
PROJECTION
"proj=tmerc"
"ellps=bessel"
"lat_0=0"
"lon_0=13.33333333333333"
"k=1.000000"
"x_0=450000"
"y_0=-5000000"
"units=m"
"towgs84=577.326,90.129,463.919,5.1365988,1.4742,5.2970436,2.4232"
END
or
PROJECTION
"init=EPSG:31285"
"towgs84=577.326,90.129,463.919,5.1365988,1.4742,5.2970436,2.4232"
END
best regards,
Christian
