Economists had warned that, in order to meet the €35bn net adjustment demanded by the EU, with falling tax revenues and an economy falling into recession, the real extra adjustment in the last nine months of the year had to reach €40bn.
Furthermore, it should improve and expand the standards for net adjustment which are unclear and not exactly reproducible at the moment.
Another explanation for this could be the way in which the fixed points are chosen at the net adjustment of the triangulation survey.
Each elevation was determined by geodetic net adjustment (e.g., Bonford 2012) referenced to the elevation of A0, and the elevation of the datum point A0 was determined by the leveling from a second-order benchmark (BM2167-7) administered by GSIJ.
Therefore, the estimated horizontal displacements are appropriate, but on the northwest side of the triangulation net, where no fixed points exist, a northwestward-southeastward strain could be introduced by the net adjustment.
Each elevation was determined by geodetic net adjustment (e.g. Bonford 2012) referenced to the elevation of A0, the datum point which was determined by levelling from a second-order benchmark (BM2167-7) provided by the Geographical Survey Institute of Japan.
