For a project we are wishing to use use openlayers. I know how to plot points and have a popup bubble. However since there is going to be quite a lot of points plotted on the map for the UK. What i am wanting to do is send the central point of the viewable area and in the backend send a layer update of all the points in the current viewable area. In openlayers is there anyway of doing this?

Yes. You can either use a WMS server to serve maps as images, or use the BBOX Strategy to only get the content within the viewport.
是。您可以使用WMS服务器将地图作为图像提供，也可以使用BBOX策略仅获取视口中的内容。
