Cesium support VN2000 georeference system

CesiumJS
1

Hi everyone,

Currently, most of our models are using VN2000 with georeferenced system, but seem like Cesium JS SDK does not support VN2000.

Is there something that I miss or does Cesium team have any plan to implement this?

Thank you.

Hi there,

What are you looking to use the projection for in CesiumJS? In some cases, it may not be needed or we may be able to recommend a workaround.

For imagery layer support, please follow the feature request at different projections · Issue #3877 · CesiumGS/cesium · GitHub

Hi Gabby,

We want to upload models of entire area of a province in Vietnam, and these models should be displayed at exact location that we have predefined for the models before. The georeference system we are using is VN2000.

In case Cesium does not support VN2000, we have to re-locate the models manually, and it does not fit our purpose.

If there is any workaround, please guide me.

Thank you

Hi @Portcoast,

CesiumJS does not directly use VN2000 coordinates, but it should be straightforward to convert the positions in an automated fashion without loosing precision using tools like proj. Since CesiumJS is a 3D engine, there is no need to use a 2D projection like VN2000.CesiumJS uses the 3D coordinate system WGS 84 - EPSG:4978.

Thank you Gabby. I will give it a shot.
