Module sampling

Sampling and extraction methods. Sampling and extraction methods for RasterDataset.

This module contains methods for extracting values from raster blocks at vector points.

Functions

assemble_block_results 🔒

Shared helper: assembles parallel block results into a BTreeMap. Generic over the key type (i16 or i64).

build_block_index_pipeline 🔒

Shared helper: builds the index-to-blocks pipeline. Returns (id_indices, blocks_to_process) from geometry data.

collect_points_for_block 🔒

Shared helper: collects pos/idx/pids for a given block ID.

make_rectangle 🔒

Shared helper: creates a Rectangle from buffer size.

sample_value 🔒

Samples a value from a 2D array at the given point using the specified method.

validate_buffer_size 🔒

Shared helper: validates buffer size against overlap size.
