Osm.el is a tile-based map viewer, with a responsive movable and zoomable display. The map can be controlled with the keyboard or with the mouse. The viewer fetches the map tiles in parallel from tile servers via the `curl' program. The package comes with a list of multiple preconfigured tile servers. You can bookmark your favorite locations using regular Emacs bookmarks or create links from Org files to locations. Furthermore the package provides commands to measure distances, search for locations by name and to open and display GPX tracks. osm.el requires Emacs 27 and depends on the external `curl' program. Emacs must be built with libxml, libjansson, librsvg, libjpeg and libpng support.
