Hi @dipperpine0411,

Welcome to the Cesium community!

Could you give a little bit more detail about:

  • What you’re trying to achieve? (A reference image or example sandcastle could go a long way)
  • What exactly the issue is? (An error or crash? Something just doesn’t look right?)
  • Which version of Cesium you’re using? (Is this for Unreal / Unity, CesiumJS (web)? Which version?)

Thanks,
Matt

Hi @mzschwartz5 . Thank for you reply. Currently, i want add label to display height for each contour line. I haven’t found a way to display it correctly yet. I’m using cesium web version 1.136. Thanks

Are you able to provide a demo sandcastle showing how you’re drawing the contour lines, so I can see what APIs you’re currently using?

In general, to add labels in CesiumJS, you would use the Label API (often starting by adding a LabelCollection and adding labels to it).

If the contour lines are part of, say, a GeoJsonDataSource, you could iterate through the entities in the data source and add labels to entities according to your application’s needs. Here’s a sandcastle eexample that loads from geojson.
