convster#
convster — Spatial filter application and derived metric computation for raster maps.
This package provides tools for applying spatial filters (e.g. Gaussian blur) to land-cover type raster maps and for computing per-cell derived metrics such as Shannon entropy and multi-layer interaction values. Processing is designed to work block-wise for memory-efficient handling of large rasters.
Submodules#
- filters
Implementations of spatial filters ready for use with raster data, including Gaussian blurring via
gaussian.- helper
Array utility functions, including non-zero index lookups used internally during filter application.
- processing
Functions for category selection, entropy computation, and multi-layer interaction metrics. Supports per-category filtering and rescaling.
- parallel
Parallelized application of filters and entropy/interaction computations across spatial blocks of a raster.
