Python and Java API / Defining vertical datum when exporting point clouds

« on: September 05, 2022, 05:24:16 PM »

Hi,

When exporting the point cloud using exportPoints() function I can define only the output CRS but not the vertical datum as well. Is there any possibility to define the vertical datum (using EPSG ideally) so that it's also written to the header of the LAS/LAZ file?

Python and Java API / Exported point clouds have coordinates moved closed to zero

« on: October 19, 2021, 05:05:19 PM »

Hi,

I'm using Metashape Python API (v1.6) and I noticed that when exporting point clouds as LAZ the output file has coordinates in local coordinate system instead of the one defined for the chunk. Isn't it that by default, if crs is not explicitly defined it should export the points to chunk's crs?
For the other exports (DEM, Orthophoto, etc) all works fine.

I do the point cloud export like below

Code: [Select]

chunk.exportPoints(output_fpath, format=PointsFormatLAZ)


Thanks in advance.

Python and Java API / Exported PDF report has black squares instead of text

« on: February 03, 2020, 03:23:05 PM »

When using using Metashape Pyhon API (v 1.6) for PDF report export I get PDF where there are black squares instead of text (titles, ...). Can't figure out why is that happening. I'm running the code on Ubuntu 18.04.

Screenshot is in attachment.
