Jan 17	comment	QGIS & GeoMedia .mdb .gws compatibility? Try to explore on the Geomedia MDB database GDAL/OGR >= 1.9.0 page but have no idea how to start. further instruction and recommendation are most welcomed.
Jan 17	comment	QGIS & GeoMedia .mdb .gws compatibility? Yup, try that but with no luck, received error "invalid data source", but my GeoMedia file can be opened with ArcGIS with FME plug-in directly.
Jan 16	comment	Predefined CRS and Custom CRS problem with Borneo projection Noted with thanks, will further explore on it
Jan 16	comment	Predefined CRS and Custom CRS problem with Borneo projection any good tool apart from spatial reference to generate the proj4 string from WKT format for use in GIS FOSS?
Jan 14	comment	Predefined CRS and Custom CRS problem with Borneo projection thanks for all the help, my layers locating at correct position now. for the 2000000, 5000000 false easting and northing, i modified your Proj4 format to +x_0=2590476.87 +y_0=5442857.65 and it display correctly as well.

Jan 12	comment	Predefined CRS and Custom CRS problem with Borneo projection i try using spatial reference tool to generate the Proj4 format for Timbalai 1948/ RSO Borneo (m) `+proj=omerc +lat_0=4 +lonc=115 +alpha=53.31582047222222 +k=0.99984 +x_0=590476.87 +y_0=442857.65 +ellps=evrstSS +units=m +no_defs` and assigned the shapefile to this new custom CRS. the output still cannot match the two CRS together. the new user defined CRS using spatial reference tool still go to North 300,+++Km

Jan 12	comment	Predefined CRS and Custom CRS problem with Borneo projection i insert few dumpscreen into original post to show how i create the custom user defined CRS. please kindly help to inspect and hopefully i get the right procedure to do it.
Jan 12	comment	Predefined CRS and Custom CRS problem with Borneo projection @AndreJoost Yes, the newly saved shapefile displaced as well. but if re-assigned to EPSG:29873, it will be back to the desired place. so i assumed i did not create the user defined CRS correctly.
