[mapserver-users] Coordinates shifted for EPSG:28992

[Just van den Broecke]

Hi All,

On Ubuntu 20.4 with Proj Rel. 6.3.1, February 10th, 2020 and MapServer 
7.4.3 with Proj, the transformation from EPSG:4326 to EPSG:28992 is 
shifted.

Findings:
- projinfo for EPSG:28992 shows correct proj-string
- cs2cs gives correct results
- when adding the proj-def explicitly to each layer: correct results
- did not occur on older MS+proj.4-versions on Ubuntu 16.

Looks like a Datum shift problem, shift is around 80m NE, but towgs84 is 
in the proj-string from projinfo.

The proj string is:
<28992> +proj=sterea +lat_0=52.15616055555555 +lon_0=5.38763888888889 
+k=0.9999079 +x_0=155000 +y_0=463000 +ellps=bessel 
+towgs84=565.417,50.3319,465.552,-0.398957,0.343988,-1.8774,4.0725 
+units=m +no_defs <>

Any help appreciated.

Best,

Just van den Broecke
