Lars<br>You might want to find out a bit more about Query-to-map being developed by kolossos. It shows not just point features but also linear features such as rivers and roads. I believe it's hosted on Wikimedia's toolserver and is intended ultimately to be used on Wikipedia pages.<br>

These days I spend more time in Wikipedia than in OpenStreetMap,<br>
but I haven't lost my interest in geography. Among the many things<br>
that need improvement in Wikipedia is the geographic coordinates<br>
that indicate the location of places, buildings, cities, and such.<br>
<br>
The OSM wiki has a <map> tag that looks like this:<br>
<map lat=63 lon=16.5 z=5 w=360 h=720 /><br>
<br>
In the page [[WikiProject Sweden]], this shows a 360x720 pixel<br>
image based on zoom 5 map tiles centered around 63° N 16.5° E.<br>
<br>
Is this a user-friendly way to put a map in a wiki page? Would<br>
normal users understand the z= parameter, or should the parameters<br>
be designed some other way?<br>
<br>
Could the editing be made interactive, so that the user can see<br>
the map on the edit page and zoom and pan, and when pressing the<br>
"save" button the new coordinates are saved? This would take out<br>
the hard work for "numerically challenged" contributors.<br>
<br>
Should we try to introduce the map tag in Wikipedia? Has it<br>
already been tried, and what was the reaction? Do we have any bad<br>
experience from its use in the OSM, to learn and improve from?<br>
<br>
It's not easy to convince the tech staff of Wikipedia to introduce<br>
new features. They probably receive such requests daily. The code<br>
must run, it must scale very well, and be very stable. If we<br>
really want to introduce the <map> tag (or something similar) in<br>
Wikipedia, we must provide really good arguments.<br>
<br>
Fortunately, there is a Wikipedia developer meeting on April 3-5,<br>
where I could bring this forward.<br>
<br>
In Wikipedia, map coordinates are typically placed in an infobox,<br>
as seen on <a href="http://en.wikipedia.org/wiki/Sweden" target="_blank">http://en.wikipedia.org/wiki/Sweden</a><br>
or at the right top corner of the page,<br>
as seen on <a href="http://en.wikipedia.org/wiki/R%C3%B6k_Runestone" target="_blank">http://en.wikipedia.org/wiki/R%C3%B6k_Runestone</a><br>
<br>
In either case, the coordinates form a link to a switchboard page<br>
titled GeoHack where you can chose your favorite map site,<br>
including Google Maps or OpenStreetMap.<br>
<br>
Next to the coordinates is also a little blue marble. If you click<br>
on this, you bring up a pop-up map called WikiMiniAtlas. This<br>
little map can be panned and zoomed and features links to other<br>
articles. But it uses primitive VMAP-0 data as background and has<br>
no proper projection, just the naive x=lon, y=lat.<br>
<br>
In Wikipedia, the coordinates are given like this:<br>
<br>
{{coord|58|17|42|N|14|46|32|E|display=title|type:landmark}}<br>
<br>
Even though decimal degrees can also be used, most articles use<br>
degrees-minutes-seconds. The display=title parameter puts the<br>
coordinate in the upper right corner. The type:landmark parameter<br>
(yes, a colon is used here, not equal sign) sets the scale for the<br>
resulting map. Of course, zoom=5 is specific to OpenStreetMap.<br>
Other map sites use different definition of zoom or scale. The<br>
GeoHack switchboard page converts type:landmark to the appropriate<br>
zoom for each target map site.<br>
<br>
I think WikiMiniAtlas is fine, despite some flaws. But when I<br>
explain this to others, even experienced wikipedians, many say<br>
they didn't figure they could click on the blue marble to show the<br>
pop-up map. That's why I think an inline presentation (like the<br>
map tag) would be a necessary improvement. More visible maps will<br>
lead to more eyeballs, finding more errors in incorrect data.<br>
