Hey all. I'm trying to render coastlines in an app that I am building using OSM data (The rendering engine just draws shapes and I have to determine what shapes to draw). I've been able to learn a lot from the wiki about how coastlines are created (anti-clockwise and joined end on end), but still have an issue with deciding where there is sea and where there is land if zoomed into an area with no features.
>From what I saw, there is a binary file somewhere that maps out the land / sea areas that you can query if you find no coastline ways etc. Is this the best / only approach? If so, where could I find this file? Should I create one myself? Does it work well over the whole globe? Does anyone with coastline rendering experience have any suggestions on how best to solve this problem? I'd really appreciate any input as I want to render coastlines in real-time using the data pretty much as is (i.e. not convert to shape files etc). This is for a client side application using real-time rendering, so I am looking for the fastest approach.
