gdalraster - Bindings to the 'Geospatial Data Abstraction Library' Raster API
Interface to the Raster API of the 'Geospatial Data
Abstraction Library' ('GDAL', <https://gdal.org>). Bindings are
implemented in an exposed C++ class encapsulating a
'GDALDataset' and its raster band objects, along with several
stand-alone functions. These support manual creation of
uninitialized datasets, creation from existing raster as
template, read/set dataset parameters, low level I/O, color
tables, raster attribute tables, virtual raster (VRT), and
'gdalwarp' wrapper for reprojection and mosaicing. Includes
'GDAL' algorithms ('dem_proc()', 'polygonize()', 'rasterize()',
etc.), and functions for coordinate transformation and spatial
reference systems. Calling signatures resemble the native C,
C++ and Python APIs provided by the 'GDAL' project. Includes
raster 'calc()' to evaluate a given R expression on a layer or
stack of layers, with pixel x/y available as variables in the
expression; and raster 'combine()' to identify and count unique
pixel combinations across multiple input layers, with optional
output of the pixel-level combination IDs. Provides raster
display using base 'graphics'. Bindings to a subset of the
'OGR' API are also included for managing vector data sources.
Bindings to a subset of the Virtual Systems Interface ('VSI')
are also included to support operations on 'GDAL' virtual file
systems. These are general utility functions that abstract file
system operations on URLs, cloud storage services,
'Zip'/'GZip'/'7z'/'RAR' archives, and in-memory files.
'gdalraster' may be useful in applications that need scalable,
low-level I/O, or prefer a direct 'GDAL' API.
