15 February 2018 - New Geodetic App Version
A new version of the Geodetic Marks App is available for Apple mobile devices. An Android version is also available. This new version includes several major enhancements.
Orthometric Height Discrepancy - Update Complete
The NZGD2000 Kaikoura deformation model update included a correction for both ellipsoidal and orthometric heights. The NZGD2000 ellipsoidal heights were then further updated using the results of a least squares adjustment. This led to a discrepancy between orthometric heights in the database and orthometric heights calculated from the NZGD2000 ellipsoidal heights.
The NZVD2016 heights have now been updated.
Local vertical datum heights have not been updated, but new transformation grids will be published, in the next couple of months, to better reflect the new relationship between NZGD2000 and the local vertical datums.
