displayRAT

<code>displayRAT()</code> generates a presentation table. Colors are shown if the
Raster Attribute Table contains RGB columns.
This function requires package <code>gt</code>.

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.
