How to add a layer with a spatial reference different from WGS84(eg GCS2000 WKID=4490)

I had add a imageryLayer whose spatial reference was wkid=4490. I got an error which indicated that wkid=4490 was not supported.
How should I fix this problem.

Besides, where can I configure the tileMatrixSet like this:

  1. “lods”: [{

  2.        "level": "EPSG:900913:8",

  3.        "scale": 2183915.0935581755,

  4.        "resolution": 611.4962261962892

  5.      }, {

  6.        "level": "EPSG:900913:9",

  7.        "scale": 1091957.5467790877,

  8.        "resolution": 305.7481130981446

  9.      }, {

  10.        "level": "EPSG:900913:10",

  11.        "scale": 545978.7733895439,

  12.        "resolution": 152.8740565490723

  13.      }, {

  14.        "level": "EPSG:900913:11",

  15.        "scale": 272989.38669477194,

  16.        "resolution": 76.43702827453615

  17.      }, {

  18.        "level": "EPSG:900913:12",

  19.        "scale": 136494.69334738597,

  20.        "resolution": 38.21851413726807

  21.      }, {

  22.        "level": "EPSG:900913:13",

  23.        "scale": 68247.34667369298,

  24.        "resolution": 19.109257068634037

  25.      }, {

  26.         "level": "EPSG:900913:14",

  27.        "scale": 34123.67333684649,

  28.        "resolution": 9.554628534317018

  29.      }

Is this the projection you’re talking about?

We have an issue open to add more projection support (https://github.com/AnalyticalGraphicsInc/cesium/issues/3877). For now the easiest thing would be to re-project it into WGS84. As for the tileMatrixSet question, if you’re uploading data to ion (cesium.com/ion) you just upload the highest resolution and ion automatically generates the tiles at different levels of detail.
