Features

Load gravimeter observation files (Scintrex CG-5, CG-6 in multiple formats)
Manage survey stations and gravimeter metadata
Apply tidal, atmospheric pressure, and height corrections
Run least-squares adjustment to estimate gravity values at stations
Estimate drift polynomials per survey
Export results to CSV and GIS formats (shapefile via geopandas)

Installation

pip install grav-toolbox

With optional GIS support:

pip install "grav-toolbox[gis]"
