Hello,

There’s no viewshed analysis in the current open source CesiumJS library, but that functionality is offered in AGI’s Cesium Pro product (send an email to [tim@agi.com](mailto:tim@agi.com)), and we plan on adding more analysis tools as part of our Cesium commercial offerings in the future.

Thanks,

Gabby

Hello,  
Thanks for the reply. So as there is no such support there, can I develop my own algorithm for doing viewshed analysis on cesium? Can u please suggest if I need to start with LOS approach? Please help.

Sure, you can go ahead and develop your own implementation, a LOS approach makes sense.
