FAQ
ZARR to PGM Conversion
What are ZARR files?
ZARR is an open format for storing very large multidimensional arrays of numbers, such as satellite image series, climate model output, weather forecasts, and microscope scans. A Zarr data set is cut into small chunks, and each chunk is compressed and saved on its own, so a program can read just the part it needs without loading the whole data set, and many computers can work on different parts at the same time. The format was designed for cloud storage, where data are kept as separate objects, and it is now widely used for analysis-ready geospatial data in the cloud. It is maintained by a community of developers, and an OGC community standard describes its second version.
What are PGM files?
The PGM or Portable Graymap format is part of a package of open source graphics programs called Netpbm. Other Netpbm formats include PPM (Portable Pixmap) and PBM (Portable Bitmap), also known under the collective name of PNM (Portable Anymap). A PGM file includes a grayscale image, can work on a UNIX platform, as well as on Windows or Mac OS X, and can render a scope of up to 255 grayscale colors.
