    About the Transverse Mercator (belt) family

    QND95 / Qatar National Grid is a Transverse Mercator belt — a national or cadastral grid in metres, conformal (angles are preserved), with its own central meridian and scale factor. Egypt's Red/Purple/Blue belts, the Levant grids, and many Gulf cadastral systems are of this kind.

    Two things decide whether your coordinates land correctly: the exact belt (central meridian) and the datum. Mixing a coordinate from one belt into another, or ignoring the datum shift to WGS 84, is the usual cause of a systematic offset in imported survey data.

    FAQ

    What is EPSG:2932?
    It is the coordinate system “QND95 / Qatar National Grid”, a Projected (metres) system in the Transverse Mercator (belt) family, identified worldwide by the code EPSG:2932.
    What datum does it use, and how accurate is it?
    It is based on the intl ellipsoid and it carries Helmert parameters to WGS84. The residual at the test point is about ±0.1 m versus PROJ; for centimetre work use a geodetic adjustment service.
    Where is this system used?
    It is used in Qatar. This page shows its area of use as a coordinate rectangle above.
    How do I convert EPSG:2932 to WGS84?
    Use the free coordinate converter above (preloaded with this system) to convert to WGS84, UTM, or any other system, within a ±0.1 m residual.
