projection offset

[Bart van den Eijnden (OSGIS)]

Steven,

have you updated your PROJ.4 parameters? PROJ 4.5 should contain the right
ones.

This should be it, check your epsg file:

<28992> +proj=sterea +lat_0=52.15616055555555 +lon_0=5.38763888888889
+k=0.999908 +x_0=155000 +y_0=463000 +ellps=bessel +units=m
+towgs84=565.2369,50.0087,465.658,-0.406857330322398,0.350732676542563,-1.8703473836068,4.0812
+no_defs <>

Best regards,
Bart
