geolocated notes

[Łukasz Stelmach]

Hello.

I've just created a hack to for org-mode (and org-remember) to receive
and parse URLs from OpenStreetMap and Google Maps. The function extracts
longitude and latitude and sets GEO property of the node to geo: URI.

The code is easily extendable. To add support for other maps one has to
add a branch in the `cond' in stl/org-dnd-set-geo-property, that sets
`lon' and `lat' appropriately *and* a regular expression in
stl/org-dnd-add-geo-support.

To see it running just drag and drop the URL that contains geographic
coordinates from the address bar (or the "Link" link in the upper right
corner of the Google Maps window) over a node to get its GEO property
set.

--8<---------------cut here---------------start------------->8---
(defun stl/org-dnd-set-geo-property (uri action)
  (save-excursion
    (let (lat lon)
      (cond 
					; OpenStreetMap
       ((string-match
	 "^http://\\(?:www\.\\)openstreetmap\.org/" uri)
	(dolist (p (split-string (cadr (split-string uri "\?")) "&" ))
	  (cond
	   ((string-match "lat=\\(-?[.0-9]+\\)" p)
	    (setq lat (match-string 1 p)))
	   ((string-match "lon=\\(-?[.0-9]+\\)" p)
	    (setq lon (match-string 1 p))))))
					; Google Maps
       ((string-match
	 "^http://maps\.google\.com/.*ll=\\(-?[.0-9]+\\),\\(-?[.0-9]+\\)" uri)
	(setq lat (match-string 1 uri) lon (match-string 2 uri))))
      (unless (outline-previous-heading)
	(search-forward-regexp org-outline-regexp))
      (org-set-property "GEO" (concat "geo:" lat "," lon)))))

(defun stl/org-dnd-add-geo-support ()
  (org-set-local
	     'dnd-protocol-alist
	     (append '(("^http://\\(?:\\(?:www\.\\)?openstreetmap\.org\\|maps\.google\.com\\)". stl/org-dnd-set-geo-property)) dnd-protocol-alist)))

(add-hook 'org-mode-hook 'stl/org-dnd-add-geo-support)
(add-hook 'org-remember-mode-hook 'stl/org-dnd-add-geo-support)

There are few things to do: accept `geo:' URIs[1] simply putting them in
the GEO property without any modification, some sanity and error checks
too. I am going to work on this for myself[2] but I will follow this thread
waiting for any suggestions too.

What I would like to achieve is a "geospatial aware todo list" that
enables one to choose todos along or near a route between two selected
points, so one can visit them when traveling. Probably there will be a
link to the Google Maps on the bootom of such a list to visualise such a
list.

I put the code in contrib/lisp/org-geo.el. Check it out
http://github.com/steelman/org-mode/blob/org-geo/contrib/lisp/org-geo.el
