FAQ
HFZ to BPG 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 BPG files?
BPG is a new and promising image format, which currently provides the most advanced technology in image compression. Released in 2014 by software developer Fabrice Bellard, the BPG format has been shown to include the best quality/size ratio, when compared to other popular formats such as JPG or PNG. The number of image viewers that can open BPG files is currently limited, but is expected to grow in the near future. For easier access, conversion can be done to and from the BPG format.
