gdalio:Read Data to via GDAL Warper to an Assumed Grid
Convenience wrapper for the GDAL raster warper library. Set a default context grid, an extent, dimension, projection, and then read any GDAL raster source into that grid. There are controls to augment metadata-poor sources (to override missing or incorrect extent or projection metadata), to set a desired grid for subsequent use, and ability to control options available by the GDAL warp library itself. This can be used to easily read data from any kind of raster data source, local files, online servers, bare URLs, and database connections. Data is read in generic form but we provide example wrappers for commonly used formats for raster data.

whatarelief:Get topography elevation and online imagery data
Obtain elevation data, topography relief for any region on the Earth. Topography and bathymetry data is supported by default. Sensible defaults exist for usage, with a matrix of entire planet topography(and bathymetry) returned. The geographic extent can be modified (from whole-planet) to a simple region in longitude/latitude by 'xmin,xmax,ymin,ymax' range, or by specifying a grid exactly with extent, dimension, projection in generic or spatial formats ('terra' or 'raster'). Online sources for data are used, 'GEBCO' General Bathymetric Chart of the Oceans (GEBCO) as a background (to ~500m resolution), and Copernicus GLO-30 Digital Elevation Model for higher resolution (to ~30m resolution). Custom source/s of topography may be input to override defaults, links to file/s or URLs as required.

lazyraster:Generate Raster Data Lazily from 'GDAL'
Read raster data at a specified resolution on-demand via 'GDAL' (the Geospatial Data Abstraction Library <https://gdal.org/>). Augments the 'raster' package by never reading data from a raster source until necessary for generating an in-memory 'raster' object. A 'lazyraster' object may be cropped and converted to 'raster' object, and by default will only read a small amount of data sufficient for an overall summary. The amount of data read can be controlled by specifying the output dimensions.
