How to Add Geographical Markers to Maps?

However, Jeremy from Ghost Interactive has just released his OpenZoom Overlay Extension. His work shows how to program renderers that have a sticky behavior in OpenZoom. Good ingredients are the localToScene and sceneToLocal methods on IViewport that help you convert viewport to scene coordinates. In my opinion, I see OpenZoom as a great rendering engine for mapping components along the lines of Modest Maps. I’ve experimented a bit with improving rendering specifically for mapping with OpenZoom Dourado. However, I don’t have plans to make specific mapping components for OpenZoom as it really takes time to get it right and I lack the time and experience to do it right. Nonetheless, I believe OpenZoom for mapping would make for a great community project.
