riogrande

riogrande — Raster I/O and parallel processing for GeoTIFF data.

This package provides the core infrastructure for reading, writing, and processing geospatial raster files (GeoTIFFs) with support for metadata management (tags), block-wise parallelization, and spatial windowing.

Submodules

io

Source and Band classes together with low-level I/O functions for loading and writing raster blocks.

helper

Utility functions for CRS and resolution compatibility checks, dtype conversion, tag serialization, mask aggregation, and multiprocessing setup.

prepare

Functions for decomposing a raster into overlapping or non-overlapping views (windows) suitable for parallelized processing.

parallel

Worker and aggregation functions for block-parallel raster operations, including mask computation and view-based processing.

timing

Lightweight context manager for measuring execution time and recording intermediate lap durations.
