• We pinged RAPID for additional testing on Oct 4th as this bumps the potree viewer from 1.6 to 1.8 and curious if everything works as expected for their use cases. It is deployed to staging for their testing.
• update deployed nginx conf
• confirm which version of potreeconvert (going with c2328c4 which is v2.1.1 with some additional fixes)
• confirm if we need LAStools still for building PotreeConverter
