EGM08 and local quasigeoid model in Czech Republic
Result description
Presentation on the EGU General Assembly, Vienna, April 2009. Abstract: Two quasigeoid models are tested at over 1000 points, where both normal and ellipsoidal heights are known,in a test area in the Czech Republic: a global model computed from EGM08 anda combined model containingboth long-wavelength part from EGM08 and short-wavelength part from local terrestrial gravity measurements.Although the new EGM08 was used up to degree and order 2160, the short-wavelength part of quasigeoid generatedby residual anomalies still riches values up to 14 cm. However, the short-wavelength part of quasigeoid is notimproving the quasigeoid model at some zones of the test area. These errors in short-wavelength part of quasigeoidare probably caused by systematic errors in local gravity or height data.
