-> rivers not shown
-> Lakes are above the elevation

might be related to same terrain issue we have with kml

FYI: geojson are 2D not 3D
Vector lines are not supported by Cesium yet. (only polygons and points)
If you want to test it yourself just draw a line and a polygon on the map.

@oterral Do you know when/if line will be supported in a near future?

Also tooltip on GeoJSON doesn't work

[oterral]

Yes same issue. Don't know when it will be fixed.

Official Cesium issue to watch : CesiumGS/cesium#2172

@davidoesch Can we wait on Cesium (it's high priority for them...but you never know) or should we try to patch it.

[davidoesch]

we await cesium. neede for go live BETA

[davidoesch]

we awit for the cesium patch, -review and of 2016

[gjn]

We need to push AGI a little. ClampToGround does not seem to work yet for lines.

[davidoesch]

Can you @gjn ask / post this issue in the corresponding cesium github?

[oterral]

Seems to be fixed. Line appears in 3d.

[davidoesch]

Not on mobile... Now we have even webgl crashes.

[oterral]

@davidoesch does it work with this branch ?
