The project GEO1 will be based in the Bullabulling area, using GNSS to observe survey marks along the Great Eastern Highway level traverse, extending approximately 100km. The observed height differences will be compared on the AUSGEOID2020, AUSGEOID09 and AGQG2017 (quasigeoid). These will then be compared to the spirit levelled height differences of the level traverse, with the intentions of challenging the traditional method of spirit levelling, using one-way GNSS height differences. The upgrade of benchmark (BM) SCK47 to Standard Survey Mark (SSM) will also be carried out.
