unable to open 'SRTM_NE_250m.tif' ul[0]: unbound variable about open-elevation HOT 2 CLOSED

I am running into the same problem on OSX (Unix based.)

Where would your suggested code be inserted?

I manually performed the proposed changes and then ran:

docker run -t -i -v $(pwd)/data:/code/data openelevation/open-elevation /code/create-tiles.sh SRTM_NE_250m.TIF 10 10

And it produced the same error.

I changed the file extension from .tif to .TIF and then ran:

docker run -t -i -v $(pwd)/data:/code/data openelevation/open-elevation /code/create-tiles.sh data/SRTM_NE_250m.TIF 10 10

and it worked.

So, two problems I think. 1) File is in a subdirectory and 2) file has a lowercase extension.

Thanks for the followup question. I put the code in create-dataset.sh right after download-srtm-data.sh is called.

The code I suggested might also not be targeting the correct directory for running within the docker image. It may need to be targeting ../ like so:

# Move tif files out of their folders
mv ../SRTM_NE_250m_TIF/SRTM_NE_250m.tif ../ && \
mv ../SRTM_SE_250m_TIF/SRTM_SE_250m.tif ../ && \
mv ../SRTM_W_250m_TIF/SRTM_W_250m.tif ../
# Delete the folders that used to contain them
rm -r ../SRTM_NE_250m_TIF ../SRTM_SE_250m_TIF ../SRTM_W_250m_TIF

So this would be the entire create-dataset.sh file:

#!/usr/bin/env bash

OUTDIR="/code/data"
if [ ! -e $OUTDIR ] ; then
    echo $OUTDIR does not exist!
fi

CUR_DIR=$(pwd)

set -eu

cd $OUTDIR
../download-srtm-data.sh

# Move tif files out of their folders
mv ../SRTM_NE_250m_TIF/SRTM_NE_250m.tif ../ && \
mv ../SRTM_SE_250m_TIF/SRTM_SE_250m.tif ../ && \
mv ../SRTM_W_250m_TIF/SRTM_W_250m.tif ../
# Delete the folders that used to contain them
rm -r ../SRTM_NE_250m_TIF ../SRTM_SE_250m_TIF ../SRTM_W_250m_TIF

../create-tiles.sh SRTM_NE_250m.tif 10 10
../create-tiles.sh SRTM_SE_250m.tif 10 10
../create-tiles.sh SRTM_W_250m.tif 10 20
rm -rf SRTM_NE_250m.tif SRTM_SE_250m.tif SRTM_W_250m.tif *.rar

cd $CUR_DIR

@kovar-ursa As for why you needed upper case .TIF instead of lower case .tif, I'm not sure. Is it possible that when you ran mv you specified the name of the file in the destination? The mv command will move the file, but it can also rename it. For example, SRTM_NE_250m_TIF/SRTM_NE_250m.tif ./SRMT_NE_250m.TIF would move the file out of the folder, and rename it with an upper case extension.
