Hi, Let me explain my situation. I recently created an website showing current positions of ships with googlemaps. For a couple of reasons, we want to migrate to another solution. One of the reasons is performance. With googlemaps, i parse an xml (given by a webservice) and add/update markers for every ship to show. This slows down with the number of ships to show (example, sometimes we show more than 500 ships). To be honest, i'm not sure this is a good way to work...
We are in contact with a company that offers a solution for us. They use Openlayers. We have seen a demo and its very fast. I dont think they add "markers" for every ship. Cause, when i zoom, the object also zooms, and then refresh to the correct size it was before. How do they do that? Its extremely fast, less than a second to show a 1000 of objects on a map. i'm given the task to investigate the possibilities of Openlayers, and decide whether we can implement everything ourselfs (with openlayers), or just buy the solution of that company. i'm afraid that, with my "solution", adding so many markers, the website would'nt be that fast. What is the best way to put 500 - 1000 "markers" on a map? (and refresh, when refreshing in googlemaps, i had to update the marker-objects to prevent flickering) Sometimes a have to draw lines between them (tracking). (i know of the image caching problem in IE) I see i can add Markers, GML, geoRSS. So, which one do i use? i could create a webservice that gives me a GML, so i only have to load it, but is this fast? or do i use my googlemaps way, adding markers and updating those markers (slow)?
