Tiếp cận khái niệm về mặt Quasigeoid
Tạp chí Khoa học Đo đạc và Bản đồ, 2010 Molodenskii M.X. đưa ra mặt Quasigeoid để biểu diễn độ cao chuẩn từ mặt vật lý của Quả đất theo đường vuông góc với mặt Ellipsoid. Tuy nhiên trong các tài liệu về Trắc địa cao cấp giải thích về mặt này rất khác nhau, thậm trí coi mặt này chỉ là sản phẩm của quá trình xác định độ cao chuẩn của các điểm trên mặt vật lý của Quả đất.

Using models of the ocean's mean dynamic topography to identify errors in coastal geodetic levelling [PDF]
, 2014 Identifying errors (blunders and systematic errors) in coastal geodetic levelling networks has often been problematic. This is because (1) mean sea level (MSL) at tide gauges cannot be directly compared to height differences from levelling because the ...
