Cesium.createWorldTerrain() Offline Environmental Issues


I’m trying to implement a cross path in cesium.
When you run the “Cesium.createWorldTerrain()” function in an offline environment, the “_availability” attribute is displayed as undefined.

There is a problem in implementing a cross path due to this problem.

Is there a solution?



Welcome to the community! What exactly do you mean by a cross path? We put together a demo that can help users get started with CesiumJS offline.

I suggest you use this code as a reference when building your offline application. You will of course need to provide a URL that links to a file that is stored or hosted locally. Please let me know if you have any other questions or concerns. I am looking forward to learning more!


I would like to analyze the topography and graph it.

Is there an example to refer to this function?


Thank you for sharing some more information about your use case. As far as I know, we do not have a function in our API that will automatically graph elevation data over a given polyline. However, the following demo showcases how to add a polyline to the top of a 3D Tileset.

This demo also showcases how to get the height of the polyline at various locations. In terms of visualizing the data that you will retrieve from our API, I did a little bit of research and it seems like ploty is a great graphing API.

Let me know if you have any other questions or concerns! Your project seems really cool :grin: I am looking forward to seeing your progress.
