Methodology Investigation for Improvement on Regional Geoid Modeling & Contribution of Recent Gravity Field Satellite Missions and Satellite Altimetry Data to Geoid Model Improvement
The two years project, in period of 2015-2017, investigates computation algorithms for determination of regional geoid surface with optimal accuracy as a reference for the future national height system. Beside the performance of the computation method, the accuracy of the data which are used in computation of geoid model has also prior role in the obtained accuracy of the regional geoid model. Today development in satellite techniques and improvement of data accuracies and resolutions are very promising in improvement of regional geoid models that are calculated with the contribution of these data. In content of the project:
- the methodological research for improvement of regional geoid model accuracy, and
- the contribution of the data from recent satellite gravity missions (GRACE&GOCE) and altimetry satellites to the accuracy of the regional geoid model in Turkey are investigated and clarified.
