My team is working on an application that has a map feature, and we want to extend this feature greatly. Among other things, we want the user to be able to load a CAD drawing, and place it on the map. The map is just a single image right now, but we want a more advanced and flexible solution, like eg. tile based. Some of our users have showed us some CAD drawings (DWG) they want to use, and they are absolutely huge, so we are afraid that performance will be bad. I have snooped around and found that (eg.) bing maps support map tile overlays, and I guess that converting the huge CAD drawings to overlayed map tiles could make performance much better, while still maintaing a certain level of control, like clicking layers on and off. But how can I convert the CAD drawings to map tiles from within our application? Is there any API out there that can help with that? In C#?
