Features / enhancements

GDAL CLI bindings

• gdal_run(): add argument setVectorArgsFromObject (gdal_run(): add argument setVectorArgsFromObject #790)
• add GDALAlg::getExplicitlySetArgs(): exposed class method to return a named list of arguments that have been set explicitly along with their values (Add GDALAlg::getExplicitlySetArgs(): return a named list of arguments that have been set explicitly along with their values #807)
• add GDALAlg::setArg(): exposed class method to set algorithm argument values individually by API (Add GDALAlg::setArg(): exposed method to set algorithm argument values individually by API #822)

Raster

• class GDALRaster: add helper methods for iterating I/O on raster blocks, or on multi-block chunks of user-defined size, readBlock() / writeBlock(), make_chunk_index() and readChunk() / writeChunk() (class GDALRaster: add helper methods for iterating I/O on raster blocks, or on multi-block chunks of user-defined size #819)
• add make_chunk_index() stand-alone function for use without a dataset object
• add GDALRaster::getMinMaxLocation(): compute the min/max values for a raster band and their locations, using GDALComputeRasterMinMaxLocation() in GDAL >= 3.11 (Add GDALRaster::getMinMaxLocation(): compute the min/max values for a raster band and their locations, using GDALComputeRasterMinMaxLocation() in GDAL >= 3.11 #820)
• rasterToVRT(): add argument krnl_fn supporting a Function element in KernelFilteredSource with GDAL >= 3.12, one of "min", "max", "stddev", "median" or "mode" (rasterToVRT(): add argument krnl_fn supporting a Function element in KernelFilteredSource with GDAL >= 3.12 #821)
• class GDALRaster: add a constructor with allowed_drivers argument (class GDALRaster: add a constructor with allowed_drivers argument #793)

Multidimensional raster

• add mdim_as_classic(): return a view of an MDArray as a "classic" GDALDataset (i.e., 2D), and add column multidim_raster (TRUE|FALSE) in the data frame output of gdal_formats() (Add mdim_as_classic(): return a view of an MDArray as a "classic" GDALDataset (i.e., 2D) #799)
• add mdim_info(): report structure and content of a multidimensional dataset, interface to gdalmdiminfo utility
• add mdim_translate(): convert multidimensional data between different formats, and subset, interface to gdalmdimtranslate utility (Add mdim_translate(): convert multidimensional data between different formats, and subset #803)

Geometry API

• add g_geom_count(): return the number of elements in a geometry or number of geometries in container
• add g_get_geom(): fetch a geometry from a geometry container
• add g_unary_union(): wrapper for OGR_G_UnaryUnion()
• add g_concave_hull(): wrapper for OGR_G_ConcaveHull()
• add g_normalize(): wrapper for OGR_G_Normalize()
• g_delaunay_triangulation(): add argument constrained, wrapper for OGR_G_ConstrainedDelaunayTriangulation()
• add plot_geom(): plot WKT or WKB geometries

Other features

• add gdal_get_driver_md(): retrieve driver metadata (Add gdal_get_driver_md(): retrieve driver metadata #795)
• add vsi_stat_exists(), vsi_stat_type() and vsi_stat_size(): specializations of vsi_stat() operating on a vector of potentially multiple file system object names (Add vsi_stat_exists(), vsi_stat_type() and vsi_stat_size() #825)

Bug fix

• fixes for ogr_ds_delete_field_domain(), and condition tests on GDAL 3.12 (Fixes for ogr_ds_delete_field_domain(), and condition tests on GDAL 3.12 #823)
• ensure that the global error handler is restored when the input dataset cannot be opened in some OGR management functions (Ensure that the global error handler is restored when the input dataset cannot be opened in some OGR management functions #787)

Internal

• various C++ code linting, small refactorings and performance improvements (Lint: various C++ code linting #788, Lint: use unique_ptr #801, Various C++ code linting, small refactorings and performance improvements #818)
