[Qgis-user] matching .prj (ArcGIS) with CRS in QGIS

[K Imran M]

Hi all,

I am new to GIS so I apologize for this rather basic question.

I have a shapefile (ArcGIS) with the corresponding .prj file coded as below:

PROJCS["Kertau_RSO_Malaya_Meters",GEOGCS["GCS_Kertau",DATUM["D_Kertau",SPHEROID["Everest_1830_Modified",6377304.063,300.8017]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],PROJECTION["Rectified_Skew_Orthomorphic_Natural_Origin"],PARAMETER["False_Easting",804671.299775],PARAMETER["False_Northing",0.0],PARAMETER["Scale_Factor",0.99984],PARAMETER["Azimuth",-36.97420943711801],PARAMETER["Longitude_Of_Center",102.25],PARAMETER["Latitude_Of_Center",4.0],PARAMETER["XY_Plane_Rotation",-36.86989764584402],UNIT["Meter",1.0]]

My questions are:
1) when I call this shp file into QGIS, which CRS should I choose to match
the prj file?

2) does it match the Kertau (RSO)/RSO Malaya (m) (EPSG:3168) which has
these codes

+proj=omerc +lat_0=4 +lonc=102.25 +alpha=323.0257905 +k=0.99984
+x_0=804670.24 +y_0=0 +no_uoff +gamma=323.1301023611111 +a=6377295.664
+b=6356094.667915204 +units=m +no_defs

3) or does it match the Kertau (RSO)/RSO Malaya (ch) (EPSG:3167) which has
these codes

+proj=omerc +lat_0=4 +lonc=102.25 +alpha=323.0257905 +k=0.99984 +x_0=40000
+y_0=0 +no_uoff +gamma=323.1301023611111 +a=6377295.664
+b=6356094.667915204 +to_meter=20.116756 +no_defs

Any help is greatly appreciated

Thanks

Kamarul
