please<BR></FONT><BR></DIV>
<DIV></DIV>Hi All,<BR><BR>I am looking at building an openlayers projects which
will be pretty simple, base data with some points on top. Users will be able to
click on the points to get extra info or link to another page. My questions is
about the best way to display these points. I can see the following options
<BR><BR>1) Serve points as a WFS layer from geoserver and registers a click
event on the map to get info<BR>2) Serve points as a WMS layer from geoserver
and registers a click event on the map to get info<BR>3) Roll my own Ajax
function to pull coordinates out of the points file and create a new
vector.marker layer.<BR><BR>I wold appreciate any advice/suggestions people may
have at to the best approach to take in terms of speed, scalability and
maintainability. <BR><BR>There will be about 150,000 points to begin with but it
could rise to about 400,000. These will probably only be displayed at large zoom
levels ( i.e. small area)<BR><BR>Thanks in advance<BR>Jerry<BR></BODY></HTML>
