going to try and add my own image data ... and just need a sanity check before starting. the data i'm going to add-in is from a proprietary tile server. so i can't just add it to the XML configuration. nor do i want to create a server thunking layer. the tiles served come in multiple zoom levels (divisible by 2). so this looks like it fits with the current LevelZeroTileSizeDegrees and NumberLevels setup. i just need to do the degree conversion for the first level. i'm assuming L0TD does not have to start out at 2.25, or some value in that series (e.g. it could be 3.0)? it will also need a bit of UI for configuration. so this has me looking at the BMNG Add-in. looks like i can add to the RenderableObjectList and create my own QuadTileSet. then it looks like i can subclass ImageTileService to return the proprietary image url to retrieve a tile. might have to subclass ImageAccessor too, but haven't looked closely. i'll also have to reproject the tiles at some point.
am i missing something? or is there some other way that i should be attempting this?
