FAQ
GRI to JP2 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 JP2 files?
JP2 or JPEG 2000 is an improved version of JPEG, one of the most popular file formats for storing and transferring images. Compared to the latter, JP2 image files offer higher quality and smaller size images by using a different compression algorithm, which can be either lossy or lossless. JP2s are created using the JPEG2000 Core Coding application, but can also be obtained through conversion from other formats.
