Example on how to use lax file? #61

Closed neverwiredhouse closed 5 years ago

neverwiredhouse commented 6 years ago

I want to grab small subsections of lidar and analyze them,

I have an .las and a .lasx but I assume the lasx is just a lax.

Was looking through other issues, examples, and the code itself, still a little iffy on how to approach reading data. I've been reading entire files and just snagging the ones within my bounding box, but it's drastically slower then I think I can achieve and I need to do this roughly 20k times, so I need to improve the algorithm or it will take weeks as opposed to what I would assume could be just hours.

Those .lasx files are proprietary closed clone crap by ESRI and not the open source .lax files produced by lasindex.

Shoot! -_-

Good to know, Well indexing them using this tool I understand how to do. If I create a bunch of index lax files can you point me in the right direction to utilize them?

Basically, which api command I should use?
