# GeoidLab Documentation

GeoidLab is a Python package for gravity-field analysis and geoid computation using the remove-compute-restore (RCR) method. It provides command-line and Python APIs for observation preparation, terrain and gravity modelling, geoid estimation, and visualization.

## Features

- Complete RCR implementation for geoid determination
- Survey-table normalization for GeoidLab-ready inputs
- Multiple Stokes' kernel modifications
- Automated data downloads (DEMs, GGMs)
- Advanced gridding and interpolation options
- Comprehensive tide system support
- Multiple reference ellipsoid support
