FAQ
HDF4 to GIF Conversion
What are HDF4 files?
HDF4 is the name of the fourth generation of the Hierarchical Data Format, a file format for storing large and varied scientific data, first created at the National Center for Supercomputing Applications and later looked after by The HDF Group. All versions from the first to the fourth are essentially the same format, which is why files from the 1990s can still be opened today. It is used to keep measurements from satellites and other instruments, climate and ocean model results, and images that come with the data that describes them. The format was later replaced in new projects by HDF5, which is a completely different design and not compatible with it, but a very large archive of Earth observation data remains in HDF4.
What are GIF files?
GIF (Graphics Interchange Format) files are widely popular due to their ability to store animations and images in a relatively small size. Their compression algorithm implies the use of a limited color range (up to 256 colors), which means GIF files are great for storing static and animated images of a small size — like logos, icons or avatars, especially if you plan to transfer them or upload them online. GIF images, however, are usually not suitable for high-quality image rendering or printing.
