Updates to standardize LAS format / metadata

[dlebauer]

LAS files should follow OGC las 1.4 standard

• specification: https://www.asprs.org/committee-general/laser-las-file-format-exchange-activities.html
• relevant article https://rapidlasso.com/2016/01/10/create-proper-las-1-4-files-with-lastools-for-free/
• Follow a similar convention to meteorology and hyperspectral use of CF naming conventions where applicable and consistent w/ standard
• also use geojson polygon representation of bounding box

Goal is for (raster, point cloud) files to differ where it is useful, but have similar interfaces where applicable.

Are all x,y,z units in m relative to the gantry origin?

Description

Completion Criteria

• standard format defined
• added to extractor
• old las files updated

@solmazhajmohammadi we can follow up about this - we should be able to implement this to existing extractor.

@solmazhajmohammadi - please provide an update/next steps

Bounding box depends on Issue 44
I will work on the rest of the steps and update here

[dlebauer]

What about the other metadata? Have you looked into the OGC specifications?

@solmazhajmohammadi can this be closed?

@solmazhajmohammadi - @max-zilla needs to know if anything needs to be changed with extractor before the code freeze on Aug 15

The LAS files are in standard format as long as we are using the PDAL version >1.3
double checked with Max, we are using version 1.5
However, the ply files are still in pointcloud origin. I have updated the issue 44, in order to do the transformation.
This would georeference the LAS files.
