Look into using OpenLayers.Layer.GML with format: OpenLayers.Format.GeoJSON,
as shown with some other types here:

Hi,
I'm kind of new to OpenLayers. But I want to use GeoJSON to request geometric
features using the geometric type: MultiPoint.
The browser has no problems rendering the vector layer.
Now how do I associate an onclick event with each of these points (rather than
a collection of points).

Hi,
2000+ features is way too much for rendering in the browser.
if you use mapserver already, then you can also query the layer as WMS
layer, using sld_body with a filter. If your query is complex, use
Layer.WMS.Post instead of Layer.WMS to avoid urls that are too long for IE.

I've been having a bizarre problem where the same data (from featureserver)
has been displayed when in kml format, but not in geojson. Delving into the
code, I find this is because geojson.read throws an error if there are more
than 2 coords in a point. Why is this? 3d points are perfectly valid
Hi Eric,
I've already passed through something like this. At least the code looks
similar to me. Code is below:
var mycontext = {
getColor: function(feature)
{
var jsonvalue = feature.attributes["fillcolor"];
return jsonvalue;
}
};
var contexttemplate = {
fillOpacity: 0.

Hi Alexandre,
No. This is very similar to what I had initially except adding "select"

crop_style.pointRadius = 2;

The styleMap option must remain a vector layer option. So you now use

the vector layer ctor. Hope that helps. Eric
