Module gdal_utils

GDAL utility functions for raster processing. GDAL utility functions for raster processing.

This module provides helper functions for GDAL command-line operations including warping, translating, creating VRTs, and mosaic building.

Structs

BasicRasterInfo

Basic metadata extracted from a single GDAL dataset open.

Functions

change_res 🔒

Changes the resolution of a raster source.

compute_raster_union_extent

Compute the union extent of multiple raster files in the target CRS.

compute_single_raster_extent 🔒

Compute the extent of a single raster file in the target CRS.

compute_vector_extent

Compute the extent of a vector layer in the target CRS.

create_rayon_pool

Creates a rayon ThreadPool with the given number of CPUs.

create_temp_file

Creates a temporary file with the given extension.

extract_band 🔒

Extracts a single band from a raster source into a VRT.

file_stem_str

Extracts the file stem as a &str from a path.

get_class

Gets class IDs from a vector dataset.

get_widest_type 🔒

Returns the widest GDAL data type among all raster bands in the dataset.

mosaic

Creates a mosaic from multiple raster files.

mosaic_keep_inputs

Mosaics multiple raster files into a single output WITHOUT deleting inputs. Unlike mosaic_translate_cleanup, this preserves the input files.

mosaic_translate_cleanup

Assembles processed block files into a final output via mosaic + translate + cleanup.

mosaic_translate_cleanup_time_steps

Assembles time-step block files into a final output via mosaic + translate + cleanup.

open_for_update

Opens a GDAL dataset with update access.

raster_from_size

Creates an empty raster file with the given size and properties.

read_basic_raster_info

Opens a raster dataset once and extracts all basic metadata fields.

read_raster_band

Reads a raster band window into a 2D array.

run_gdal_command

Runs a GDAL command-line tool with the given arguments.

translate

Translates a raster file to GeoTIFF format.

translate_to_cog

Translates an existing GeoTIFF to a Cloud Optimized GeoTIFF.

translate_with_driver

Translates a raster file to a different format using the specified driver.

warp 🔒

Warps a raster source to a different EPSG projection.

warp_with_te_tr 🔒

Warps a raster source to a different extent and resolution.

write_bands_to_file

Writes each band of a 3D array to a GDAL dataset.
