Using the GridR’s core build mask API

This guide demonstrates GridR’s core masking feature, built around the grid_rasterize and grid_mask.build_mask utilities. It is split into a series of focused tutorials. Each page is self-contained and executable as a Jupyter notebook – you can follow them in order or jump directly to the topic you need.

Each page declares its prerequisites and ends with a pointer to the next logical step.

Recommended reading order

The pages are ordered for first-time readers below. Use the Previous / Next links at the bottom of each page to navigate sequentially.

1. Conventions – pixel coordinate conventions and geometry_origin

2. Rasterize – the grid_rasterize module

3. Build mask: geometries – the geometry_pair argument

4. Build mask: input raster – mask_in and related arguments

5. Build mask: combined – all masking modes together
