working with compressed tif-files #71

Closed wiesehahn closed 2 years ago

wiesehahn commented 2 years ago

I guess its more an issue related to WhiteboxTools, but since i am not sure I state it here.

Trying to run commands for compressed TIF-files results in System command had status 101.

This is just true for certain compression types (e.g. LZMA, DEFLATE with predictor), while others (e.g. DEFLATE, LZW) work. Might be related to underlying GDAL version?

Yes, this is a known issue that, I believe, is not likely to be remedied in very near future. WhiteboxTools has a custom TIF file reader and GDAL is not used at all. See the manual for more info on supported data formats https://www.whiteboxgeo.com/manual/wbt_book/supported_formats.html

It is my understanding that the primary focus of development on WhiteboxTools right now is improving/adding to the tool sets rather than trying to extend e.g. the TIFF reader to work with all the possible cases that come with that format. The R package has no control over how data files are read, it just helps with the paths. See https://github.com/jblindsay/whitebox-tools/issues/97, https://github.com/jblindsay/whitebox-tools/issues/98, discussion in https://github.com/jblindsay/whitebox-tools/issues/137, and a workaround in https://github.com/jblindsay/whitebox-tools/issues/142

If you have a sample TIF that you can easily share, then perhaps you can make an issue on https://github.com/jblindsay/whitebox-tools/issues and they may be able to address it in a future update.
