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

yxf_cn · September 5, 2018, 11:33am

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:

“lods”: [{
```
       "level": "EPSG:900913:8",
```
```
       "scale": 2183915.0935581755,
```
```
       "resolution": 611.4962261962892
```
```
     }, {
```
```
       "level": "EPSG:900913:9",
```
```
       "scale": 1091957.5467790877,
```
```
       "resolution": 305.7481130981446
```
```
     }, {
```
```
       "level": "EPSG:900913:10",
```
```
       "scale": 545978.7733895439,
```
```
       "resolution": 152.8740565490723
```
```
     }, {
```
```
       "level": "EPSG:900913:11",
```
```
       "scale": 272989.38669477194,
```
```
       "resolution": 76.43702827453615
```
```
     }, {
```
```
       "level": "EPSG:900913:12",
```
```
       "scale": 136494.69334738597,
```
```
       "resolution": 38.21851413726807
```
```
     }, {
```
```
       "level": "EPSG:900913:13",
```
```
       "scale": 68247.34667369298,
```

       "resolution": 19.109257068634037

```
     }, {
```
```
        "level": "EPSG:900913:14",
```
```
       "scale": 34123.67333684649,
```
```
       "resolution": 9.554628534317018
```
```
     }
```

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.
