This is pretty amazing! Do you know how the data was collected? What was the source format originally when you got it before converting to CZML?

Can you share the CZML here? I think the forum should let you attach that to a post.

Well.
Source format is ESRI shape.
CZML generated and sended to client programmatically during simulation.

For example, when a salmon is going along the river.
Function “cesium.mig/go-geoms-path” extracts points from a shape file, calculate and adds to the points time, generate CZML using function “czml.generator/add-point-flight” and send this to client using function “cesium.server/send-czml”.
All code on Clojure can be seen from a page:
