FAQ
HFZ to AVIF Conversion
What are HFZ files?
HFZ is the compressed version of the HF2 terrain height map format, in which the whole file is packed with the gzip method. A height map is a rectangular grid where every cell holds the elevation of one spot of a landscape, and such grids can grow very large when they cover wide areas in fine detail. HFZ keeps them small by combining two ideas: heights are stored as differences between neighboring cells, and the author chooses how precise the heights need to be. The same data can also be found with the .hf2.gz extension. In a published comparison, a terrain saved as HFZ took about 1.4 MB, while the same terrain in the TER format packed with gzip took 1.8 MB, at equal vertical precision.
What are AVIF files?
AVIF is a new image format launched at the end of 2020. AV1 Image File Format was developed by the Alliance for Open Media in collaboration with Netflix, Google and Cisco. This format was created to be an open-sourced and royalty-free image format with a super-compression efficiency. Multiple graphics compression tests show that the .avif format outperforms the JPEG, PNG and WebP image formats for its image quality to compressed file size ratio.
