ncperdomo/FICORO_GNSS: FICORO_GNSS: An open-source Python software package for filtering, combining and rotating GNSS velocity fields

FICORO_GNSS v1.3.0

🛠️ Changes from v1.2.0 Corrected the Euler pole used for rotating GNSS velocities into the Amuria-fixed reference frame in ITRF2014.

🔍 Key features:

Filter GNSS data: Remove GNSS velocity outliers based on velocity uncertainty distribution and spatial coherence of velocities Combine velocity fields: Combine GNSS velocity fields from multiple geodetic studies into a unified velocity field. Rotate to multiple reference frames: Rotate velocity fields to different reference frames using GAMIT/GLOBK integration. Manage duplicate stations: Identify and handle collocated stations with minor coordinate discrepancies across different datasets. User-friendly interface: Use Jupyter notebook for interactive and streamlined data processing.

📂 Included in this release:

Main notebook: FICORO_GNSS.ipynb – Orchestrates the data processing workflow. Input folder: raw_input/ – Contains example GNSS velocity fields in .raw format. Scripts folder: scripts/ – Houses Python scripts for automated filtering and combining processes. Manual filter folder: manual_filter/ – Includes a CSV template for defining geographic coordinates and radii for outlier removal. Documentation: Comprehensive README.md with usage instructions.

🚧 Future enhancements:

Python-based rotation and alignment modules: Eliminating the dependency on GAMIT/GLOBK in upcoming releases. Enhanced documentation: Providing more detailed tutorials and examples. Community contributions: Encouraging contributions to expand functionalities. Modular code structure: Making the code more modular by bundling common functions into modules, enhancing maintainability and scalability.
