  Streamable and read optimized file archive for hosting map tiles at global scale on a cloud object storage

This time I examined COMTiles(Cloud Optimized Map Tiles). COMTiles are often compared to PMTiles, but I have the impression that PMTiles are becoming more popular these days. The technology of COMTiles is excellent, but it is not yet easy to introduce because the library is not published in “npm,” and the documentation is incomplete. One of the reasons for PMTiles' popularity is due in part to its extensive documentation. This article will be of some help to those who are considering introducing COMTiles!

For the environment, fork "zimmermannpeter/com-tiles," a forked version of the original, or download and use it. We chose "zimmermannpeter/com-tiles" because as of December 2022, the original "mactrem/com-tiles" is still under pull request and has improved documentation and MapLibre GL JS display environment.
