Maximum size of czml file

Good morning,

I’d like to know what is the biggest size of czml file that can be loaded into Cesium. I have a 410 MB file that doesn’t get loaded; this being the error in the Sandcastle console: SyntaxError: Unexpected end of JSON input

I guess the file gets truncated because too big? I have tried with smaller files (i.e. 129 MB) and it works without problems.

I have found a similar question in the forum!searchin/cesium-dev/czml$20file$20size/cesium-dev/hekkZtC9g-8/J_QfBpXqBwA but no answer to it.

Does anyone have any idea?

Thanks and regards,


Hi Vittoria,

Just looking at file size can be a bit misleading – check out this thread which discusses KML file size, but is applicable to CZML also:

Hope that helps,
