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 search
for locations by name and to open and display GPX tracks.
- Responsive, zoomable and movable map display
- Display of tracks and POIs from GPX file
- Parallel fetching of tiles with curl
- Moving in large and small steps
- Mouse support (dragging, clicking, menu)
- Map scale indicator
- Distance measurement
- Go to coordinate
- Search for location by name
- Org link, Geo url and Elisp link support
- Bookmarked positions with pins
- Multiple preconfigured tile servers
The package is available on GNU ELPA and can be installed with package-install
.
Note that Osm.el requires Emacs 27 and depends on the external curl
program.
Emacs must be built with libxml
, libjansson
, librsvg
, libjpeg
and libpng
support. The following is an example configuration which relies on use-package
.
Please take a look at the wiki for additional configuration.
(use-package osm
:bind ("C-c m" . osm-prefix-map) ;; Alternatives: `osm-home' or `osm'
:custom
;; Take a look at the customization group `osm' for more options.
(osm-server 'default) ;; Configure the tile server
(osm-copyright t) ;; Display the copyright information
:config
;; Add custom servers, see also https://github.com/minad/osm/wiki
;; (osm-add-server 'myserver
;; :name "My tile server"
;; :group "Custom"
;; :description "Tiles based on aerial images"
;; :url "https://myserver/tiles/%z/%x/%y.png?apikey=%k")

There exist multiple methods to store a location, such that you can return there afterwards.
b
: Create a bookmark of the current location. The bookmark is stored as an Emacs bookmark inbookmark-alist
. You can jump to the bookmark via the completion commandsosm-bookmark-jump
orbookmark-jump
.l
: Store an Org link to the current location. The link can be inserted subsequently into an Org buffer withC-c C-l
.u
: Save the geo url of the current location in the kill ring. The url can be inserted in another buffer viaC-y
. A geo url has the formgeo:27.96,86.89;z=13
.C-u u
: Save an Elisp link to the current location in the kill ring. An Elisp link has the form(osm 51.49 -0.14 11)
.
Bookmarks and Org links can be created at point by clicking with the mouse. See
the docstrings of the commands osm-bookmark-set
and org-link-store
.
Click on a link or press RET
to jump to the location. These links work in Org
buffers in Emacs. Furthermore you can open Org links in arbitrary buffers with
org-open-at-point-global
. I recommend binding the command to a convenient key,
e.g., C-c o
. The format of the links complies with the geo URI scheme defined by
RFC 5870.

Place the point behind the closing parenthesis and press C-x C-e
to jump to the
location. The Elisp links can be used in arbitrary text files. Since they are
Elisp s-expressions they can be easily manipulated programatically.

Osm provides a simple distance measurement utility. In order to measure a
distance, place or select a pin by clicking with the left mouse button. Then
create one or more additional way points by pressing shift and clicking the left
mouse button. The length of the track will be shown in the echo area. You can
select the way points of the track and delete them with d
or DEL
.
Top-level commands in osm-prefix-map
. These bindings are available globally if
you bind osm-prefix-map
to a key like C-c m
. For example, to search for a
location press the key sequence C-c m s
. Furthermore the key bindings are
available in Osm buffers. There it is sufficient to press the key s
only to
initiate a search.
