Apologies in advance for the long post and a bit of rambling. I know that this might be a duplicate topic but I haven't been able to find a consolidated answer on the forums.
The tiles were premade by the client and I would prefer to use the tiles as is without reprojecting them from a WMS/TMS server.
Which I assume to mean that I have to either reproject the globe from cesium or change the tile calculation.
On 2 dimensional maps I've tried using proj4js with some success, but working with ol3-cesium puts too much things to tinker with and the default API given by ol3-cesium seems to be a bit limited.
On cesium I've tried editing the buildImageUrl() function. When changing the buildImageUrl() function I've noticed that I can get very close, but not to the correct location, and that if I tried going closer to the target location I'd have to move the tile by half a unit or so, which leads me to think that manually changing the tile requests was a faulty idea on my part.
Some of the concerns I have when working on this are:
1. the tiles provided start at level 6 instead of 0. This means that when I load the globe it attempts to load all 4096 tiles at once. I assume I can bypass this by using the camera flyto() and then adding in the imagery layer after the flyto() even, but since I haven't got the correct projection I haven't tested this out yet.
2. if I reproject the globe instead of creating a custom tile calculator, if I place terrain information that uses EPSG:4326 it would not match up with the provided image. Can anyone confirm or deny this?
3. I'm new to the whole GIS thing, so this one seems like a silly question, would Korea be usually represented by UTM51N or UTM52N? since it lies across both units, and would the other letters in the UTM scheme be used? such as S or R for Korea?
Thank you taking your time to read through this.
If further details are needed please let me know.
Thanks and Regards,
