GridTo

GridTo is an open-source software library and command-line tool designed for grid data transformation and interpolation. It provides utilities to convert data between different grid layouts, coordinate reference systems, and data formats, enabling grid-to-grid transfers in geographic information systems, meteorology, and climate science.

Key features include support for regular and irregular grids, tiling and indexing, resampling and interpolation methods (nearest neighbor, bilinear, bicubic), coordinate transformations (CRS conversion, origin shifts), and I/O adapters for NetCDF, GeoTIFF, CSV, and HDF5. The library emphasizes a modular architecture, with a grid abstraction layer, a transform engine, and extensible I/O plugins. It offers bindings for Python and C++, a command-line interface for batch processing, and a Python API for integration in data pipelines. Performance-oriented design includes streaming processing, lazy evaluation, and multi-threading capabilities.

GridTo was initially released in 2018 by GridTech Labs and has since seen contributions from an international community of researchers and developers. It is distributed under the MIT license, with active maintenance and comprehensive documentation, tutorials, and example workflows. Typical use cases include aligning climate model outputs to standard grids, converting satellite-derived raster data for analysis, and preparing data for visualization in GIS platforms.
