FAQ
GMT to AVIF Conversion
What are GMT files?
GMT is a text format for map vector data used by the Generic Mapping Tools, a widely used open-source collection of programs for drawing scientific maps and graphs, developed by Paul Wessel and Walter Smith. In its simplest form, a file is just a list of coordinates of points or lines, with a line starting with the character > marking the start of each new line. In the newer form, the file also carries a header written in comments, which names the type of shapes, the extent, the coordinate system, and the attributes of each feature, such as a name or a depth, so that points, lines, or polygons with their attributes can be kept in one file without a separate table. This version was introduced to improve exchange with other GIS programs.
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.
