Interesting. As I have going to be working on Antarctic data, I guess I
will be following your footsteps.
However, I strongly question whether your application should go the KML
route which I think are heavyweight pains in the neck to use if you can
avoid them. You state the reason for using vector is to be able to style
and select. However, the better way to go is using WMS for visualisation
and WFS for selection/query. Eg see
http://openlayers.org/dev/examples/getfeature-wfs.html
Also look at the SLDSelect example. You can pass styling to a WMS
request as well.
Compared to KML you will get faster load times (so you can have a
significant no. of features in your baselayer); geoserver will do the
projection into whatever polar system you use not JS; you can filter on
attributes (eg 'STATION_VALUE>500') which you cant do effectively with
KML (if this is important and feature no. is large, then use POSTGIS not
shapefile); GML (what you get back from WFS queries) is faster and
easier to deal with than all the KML varieties.
