Please optimize geotif export

[andrekje]

I can export geotif of huge/hires areas as tiles just fine.
- exporting to one .tif file file fails - it's "never" enough RAM for that.
please consider writing a tiled geotif - processing it as tiles, or export to tiles, then assemble to one big tif (in case that reduces the needed RAM)

I have 64GB RAM on Linux, with 96GB SSD Swap (which never gets close to filled anyway)

Hello andrekje,

In the version 1.2 you can use BigTIFF export option.

[andrekje]

Yes, and many jobs still fail when exporting to one bigtif , while the same aea can be exported to tiled tifs regardless type.

Hello andrekje,

Can you then send the log file related to the export operation and the screenshot of the export orthomosaic dialog with the parameters used?

[andrekje]

where do I find the log ?  ~/.agisoft  had no files
I've taken Christmas vacation, but reproduced on a bit lower speced computer.

Hello andrekje,

Log can be copied from the Console pane if you haven't redirected it to the text file using the option in the Preferences window.

I closed Photoscan, so I had to reproduce again:
The log is very short; , so I added comment-lines starting with //

// at this point, RAM is filled within 5sec or so  , then swap starts to increase slowly until used swap is about same amount of GB that RAM. (there is much more SSD  SWAP available )- the total memory (+swap) use seems constant after about ~3 minutes.  .. then we wait ... the progress bar does not indicate any progress ultil the end ..
