Hello,
I have used this visualizing metadata link to visualize metadata on Cesium 3D Tilesets. I am now trying to accomplish the same result with geoJSON files uploaded onto Cesium ION. I think I saw somewhere that there was a way to do it in the CesiumJS version. I was wondering if there was a way to do it in Cesium for Unreal or if there was already a tutorial out there that I am missing. Thank you in advance for your time!
Hey @dyllan-aeroai ,
Thanks for contributing to the forum! Unfortunately a full 3D visualisation of GeoJSON is not supported in Cesium for Unreal at this time. We have a Github issue open for GeoJSON support linked here, and I will add a link to this post so that we can keep track of community input. However we have made some progress towards this with these 2 pull requests:
Through 1. you should be able load your GeoJson data as a CesiumGeoJsonDocument (not a visualisation) and query your geojson through blueprints.
Through 2. you should be able to rasterise your GeoJson and overlay onto a tileset. This is a visualisation, just not a complete 3D one.
Depending on your use case, either of these may be enough for what you need.
I will also refer you to this other forum topic where @Thibault_Potier came up with a interesting workaround using python scripts to convert GeoJSON to FBX and then host those on Ion, which may be somewhere to start for you if you require a fully 3D Visualisation. @Thibault_Potier if there is any chance you would be willing to share that code (if you still have them) on your original thread I’m sure that would be very helpful to the community!
Hope that helps!
