TOPOJSON to AVIF Conversion
What are TOPOJSON files?
TOPOJSON is a compact text format for maps whose areas touch each other, such as countries, states, or districts. It extends GeoJSON with one important idea: instead of writing the outline of every area separately, it writes every shared border only once, and each area then lists the pieces of border it is made of. This removes the duplicate lines between neighbors, so a TopoJSON file is often many times smaller than the same map in GeoJSON, and it also keeps the information about which areas share a border. Because of its small size, the format is popular for maps on web pages, where files have to be downloaded quickly. The files have the .topojson extension, although .json is also used.
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.
