Gravity ground-based surveys of Southern Africa

This dataset is a compilation of several public domain ground measurements of gravity from Southern Africa. The observations are the absolute gravity values in mGal. The horizontal datum is not specified and heights are referenced to “sea level”, which we will interpret as the geoid (which realization is likely not relevant since the uncertainty in the height is probably larger than geoid model differences).

There are ~14,000 measurements in total with 4 columns available: longitude, latitude (geodetic), height (orthometric), and absolute gravity.

Format: CSV with xz (lzma) compression.
