Geo microformat

It would be good if the display of co-ordinates in each of these templates used the Geo microformat in the mark-up. Please let me know if you need further information. Andy Mabbett 08:41, 30 January 2007 (UTC)

An example of Template:Coor dms redone to include the Geo microformats can be seen here. --CBD 19:37, 31 January 2007 (UTC)

Splendid, thank you - is there an example of this in use, yet? Andy Mabbett 21:24, 31 January 2007 (UTC)

Hold that! Looking at your source code, it's broken. You can only use the title attribute on abbr elements; you have it on span. Andy Mabbett 21:39, 31 January 2007 (UTC)

Hmm... but and get printed out here... so how is it supposed to work? --CBD 22:56, 31 January 2007 (UTC)

Not sure what you mean by "printed out"? If it's a style sheet issue, the answer may be to apply different styling to the relevant classes. Andy Mabbett 23:18, 31 January 2007 (UTC)

Another solution would be to display both sets of values: Coordinates: 52°28'59"N, 1°53'37"W (52.483422;-1.895054), perhaps with the latter below the former. After all, decimal values may be more accessible, or useful, to some people (such as GPS users?) Andy Mabbett 10:50, 1 February 2007 (UTC)

I was referring to the fact that abbr tags are displayed on Wikipedia, as seen here. Changing the displayed template outputs (per your display both formats/second line ideas) would probably be difficult to reconcile with all the existing uses. --CBD 16:46, 1 February 2007 (UTC)

Thanks, but I'm still not clear what you mean about display. Can you post a screenshot, please? Could the dual display be reconciled with some uses? At least as a proof-of-concept? Andy Mabbett 16:56, 1 February 2007 (UTC)

When I click on this link I see, " {{{1}}}°{{{2}}}′{{{3}}}″{{{4}}}, {{{5}}}°{{{6}}}′{{{7}}}″{{{8}}}". Do you see something different? If not, then that's what I'm referring to... the 'abbr' sections are displayed on the screen as text rather than recognized as formatting tags. --CBD 17:55, 3 February 2007 (UTC)

I see the same as you. Not sure whether it's a bug or a feature :-( Andy Mabbett 21:09, 3 February 2007 (UTC)

I've been encountering all these sorts of issues in my work with User:The Anomebot2. It seems to me we need a MediaWiki extension for <geo> tags: there are so many perfectly reasonable ways of writing a geolocation (for example: WGS84 lat/long, OSGB36 National Grid coordinates, UTM, and so on, not to mention the various valid ways of writing these: decimal vs. dms, with/without spaces, and so on...) that we need actual software support, rather than templates alone.

Incidentally, it looks like a lot of the current UK lat/longs are being done using UK-specific datums, or even Airy 1930, which adds a lot of extra confusion, and that the National Grid Reference link server is not getting it quite right, either. (Take a look at Alexandra Palace Transmitter links to Google Maps via the NGR and the derived WGS84 location for an example: the NGR-derived WGS84 is right on the mark, to within the precision of the original NGR, and linking via the NGR server is some way out.) -- The Anome 15:11, 13 March 2007 (UTC)

Since (for example):

{{coor title d|52.41527|N|1.91615|W|region:GB_source:enwiki-osgb36(SP058797)}}

contains decimal values, and currently produces the output:

<a href="http://toolserver.org/~magnus/geo/geohack.php?params=52.41527_N_1.91615_W_region:GB_source:enwiki-osgb36(SP058797)"
class="external text" 
title="http://toolserver.org/~magnus/geo/geohack.php?params=52.41527_N_1.91615_W_region:GB_source:enwiki-osgb36(SP058797)" 
rel="nofollow">
<span title="Maps, aerial photos, and other data for 52.41527° N 1.91615° W">
52.41527° N 1.91615° W
</span></a>

it should be possible to change the output to:

<a href="http://toolserver.org/~magnus/geo/geohack.php?params=52.41527_N_1.91615_W_region:GB_source:enwiki-osgb36(SP058797)"

rel="nofollow">
<span title="Maps, aerial photos, and other data for 52.41527° N 1.91615° W">
<span class="geo"><span class="longitude">52.41527</span>° N <abbr class="latitude" title="-1.91615">1.91615</abbr></span>° W
</span></a>

or, if preferred, to:

<a href="http://toolserver.org/~magnus/geo/geohack.php?params=52.41527_N_1.91615_W_region:GB_source:enwiki-osgb36(SP058797)"

<span title="Maps, aerial photos, and other data for 52.41527° N 1.91615° W">
<span class="geo"><span class="longitude">52.41527</span>° <span class="latitude">-1.91615</span>°</span>
</span></a>

Note also that the info box created here already as decimal values using a negative number for Westings - exactly as required for the "Geo" microformat.. Andy Mabbett 18:16, 15 March 2007 (UTC)

Resolved

Please see Template:Coor/new {{coord}}, which resolves these issues (also allowing entry and use of precise decimal values, while displaying more user-friendly DMS values), and applies the Geo microforamt.
