The global map disappear after a period of time about sc-lio-sam HOT 2 CLOSED

Hi @14212094, thank you for using our system.

I also noticed the issue too, and I'm under finding the reason.

but I NOTE that the disappearing submap is only about the visualization issue,
and not having any bad effect on the motion estimation

so after running the program, you can find the result like https://github.com/gisbi-kim/SC-LIO-SAM#applications
and you would check all the estimation is alright.

if you need the optimized stacked map,
I recommend you
to use the saved Scans and the optimized poses using https://github.com/gisbi-kim/SC-LIO-SAM#applications
for the details of making a map by integrating (stacking) scans using the poses,
