Integrated Geodetic Control Network Database (INGA)
The points of the INGA network were selected from the EOMA points. High-order levelling, GNSS and, where possible, gravimetric measurements were carried out at the points.
What does it contain?
The control points of the INGA network were selected from the EOMA high-order points based on GNSS accessibility. High-order levelling, GNSS and, in some cases, gravimetric measurements were carried out at the points. The implementation of INGA commenced in 2007–2011 in accordance with the schedule for the remeasurement of the EOMA first-order network. Despite the suspension of the remeasurement programme, GNSS surveys and data processing of the selected EOMA control points east of the Danube were completed by 2014. The INGA database supports height conversion in the EHT and VITEL transformation procedures.
