Title: Raster Georeferencing, Grid Affine Transforms, Cell Abstraction
Version: 0.2.5
Authors@R: person("Michael D.", "Sumner", email = "mdsumner@gmail.com", role = c("aut", "cre"))
Description: Tools for raster georeferencing, grid affine transforms,
        and general raster logic. These functions provide converters
        between raster specifications, world vector, geotransform,
        'RasterIO' window, and 'RasterIO window' in 'sf' package list
        format. There are functions to offset a matrix by padding any
        of four corners (useful for vectorizing neighbourhood
        operations), and helper functions to harvesting user clicks on
        a graphics device to use for simple georeferencing of images.
        Methods used are available from
        <https://en.wikipedia.org/wiki/World_file> and
        <https://gdal.org/user/raster_data_model.html>.
