I have a table with x and y coordinates. It is mentioned that coordinates in "RD Bessel" system. I couldn't find it in ArcGIS and QGIS. Also no info on google?

  • There are 1 projected and 4 geographic Bessel coordinate reference systems included in ArcGIS 10.4. Have you tried those? Type 'bessel' in the coordinate reference search box. Also: en.wikipedia.org/wiki/Bessel_ellipsoid. Also, I see that there are two projections called "RD Old" and "RD New", both of which use the Bessel_1841 spheroid.

  • I saw Bessel 1841. Is it RD? Feb 24 '17 at 23:02
  • Yes, the RD systems are based on a geographic coordinate reference system (datum) that uses the Bessel 1841 ellipsoid.

My best guess is that you're looking for the "RD New" projection, or possibly "RD Old". In ArcGIS, it is found under: Projected Coordinate Systems -> National Grids -> Europe -> RD New. Both "RD New" and "RD Old" use the Bessel Spheroid.
