AW: [OpenLayers-Users] World user map

[Arnd Wippermann]

it seem to be an issue with conference.css
try 
.section img {
    /* padding-top: 5; */
    padding-top: 0;
}

Betreff: Re: [OpenLayers-Users] World user map


Thanks to the suggestion made by Barend Köbben I found this post
http://thematicmapping.org/playground/openlayers_propsymbols_geojson.php
which was showing what I need.

I've altered the example and it is now running at
http://www.mapwindow.org/conference/2012/usermap.html

But when I put the code (not that much) in the webpage with the participants
I get horizontal transparent 'lines' in my OSM base map.
Because my div has a gray background the lines are gray as well.
This is probably some CSS issue, but I haven't figured it out.

Thanks all for your help and if you have a suggestion of the fix the lines
let me know.

Hi Paul,

For such a relatively simple map I would probably not even use a WxS, just
a geojson file of a simple world map and javascript to read the attributes
of how many visitors per country. You could probably use OpenLayers for
that (which I did not try myself), but other solutions too, see e.g the
example of a simple thematic maps made with the D3 library at
http://kartoweb.itc.nl/kobben/test/buurten.html

BTW, you should of course not use a map where you color countries if a
person comes from there (a so-called choropleth or chorochromatic map).
That would greatly misdirect the user into thinking many people come from
e.g. Russia, because he sees a huge red polygon, while none seem to come
from Luxemburg (which he won't see at al at that scale). In reality maybe
20 are from Luxemburg and only 1 from Russia. Better use proportional
point symbols per country, see ge, the map "AANT_INW" in the example
mentioned above...
