FAQ
GRI to IFF Conversion
What are GRI files?
GRI is the data file of the native raster format of the raster package for the R programming environment, which is widely used for statistics and spatial analysis. It holds the cell values of a map or a satellite image as a plain sequence of numbers, without compression, and it is always accompanied by a small text file with the same name and the .grd extension. The text file describes what the numbers mean: the size of the grid, the area it covers, the coordinate system, the type of values, and the names of the layers. Neither file can be used alone. The format is simple and flexible, so it is convenient for saving intermediate results, such as terrain models, climate layers, or land cover maps, when working in R.
What are IFF files?
IFF is an old image format associated with Amiga computers — a brand connected to Commodore, which used to be popular in the 1980s and 1990s. Commodore was one of the first types of personal computers to gain wide popularity among home users. An IFF file most likely contains an image that was created or edited using an image handling program on an Amiga computer. IFF files are currently considered obsolete and uncommon, so opening them with regular image viewers might be difficult.
