[OSM-talk] POI display on osm.org

[Peter Wendorff]

Hi.

Some remarks:
1) zooming in by double click should IMHO not trigger the bubble "zoom 
in to..."

2) the bubble with the pois is too high sometimes. It looks like it's 
size may be restricted to 100% of the window height, but that's too much 
as it requires panning the map to read everything

3) in zoom levels 17+ the range for the query might be too less, at 
least as soon as there's nothing. e.g. at [1] clicking on the corner of 
a label is too far away from the POI to return any results.

4) especially for POIs not displayed on the map it might be useful to 
show an additional icon, as there's a "missing link" between "poi 
nearby" and the map.

5) POIs mapped as areas (e.g. building outlines) are not found on click 
inside the area, but only on the outline (try to click on the "real" 
icon: no result; click on the building outline nearby and you get the 
-real poi)

6) I think, the list of tags is a nice debug view, but it would be great 
to provide some kind of i18n functionality, that as a default uses more 
human readble stuff (and probably ignores some tags like source, 
created_by, ). An additional "view data" might show the raw tags again.

7) I would change your hyperlink functionality to create a hyperlink in 
the corresponding tag line instead. There the user reads a hyperlink and 
IMHO therefore expects it to be clickable, while the slight color change 
at the title is not very obvious. On top of that there are objects with 
more than one URL attatched (e.g. website and wikipedia), which again 
would lead to confusion as it's not intuitive which link would be used 
in the title.

regards
Peter
