Gdal Warp Not Found Error

Hello,

I often use RIOS as a quick way to mask out portions of a given scene using a mask (e.g. a watermask). Sometimes the resolution and projections do not match so I like the '.setReferenceImage' function within RIOS to take care of this on the fly, thus eliminating some steps I have to perform beforehand. This has always worked well for me, but recently I have had the issue:

'raise rioserrors.GdalWarpNotFoundError(msg)
rios.rioserrors.GdalWarpNotFoundError: Unable to run gdalwarp'

I have recently built a new environment for the software I use (Pete's development env so I could use the updates to TuiView I requested). I followed Pete's instructions for installing RIOS, but my env is a little hacked together due to now renamed and conflicting dependancies.

Before I try hacking around with my env again, I wanted to check if this could be an internal RIOS bug?

Thanks, Nathan

Hi Nathan,

I would say it is pretty unlikely to be an internal bug in RIOS. That part of the code has not been changed in several years.

To test your environment, just type
gdalwarp --help
and it should give you the help for the gdalwarp command. If not, then RIOS will also not be able to find it.

If this works OK, then there is something very subtle going on. However, I would still be very surprised if it internal in RIOS - I suspect your environment.

cheers
Neil

Thanks Neil,

I did forget to mention that 'gdalwarp' works fine, which was why I was perplexed as to why RIOS couldn't find it. A new release of RSGISLib is due this month so I intend on rebuilding my environment when it is released. I'll provide an update if I still have problems after a clean install.

Thanks, Nathan

I'm assuming this has been installed through conda. Could the problem be that $GDAL_DATA hasn't been set properly, which would cause gdalwarp to fail?

You could try installing rios in a new environment to make sure the latest conda-forge build works (https://github.com/conda-forge/rios-feedstock).

As this sounds like a build issue rather than one within RIOS would it be worth closing this and it if is still a problem with the latest conda-forge rios build opening a new issue there.

Since we did not hear anything back, I am assuming that the problem went away after a clean install.

Yes, I rebuilt my environment and it's sorted. My env was a bit of a mess
so a clean up seems to to have fixed it.
