GDAL Issues

1. Cryptic DLL issues

On the lab computers, if you run into the following issue with GDAL:

... the code execution cannot proceed because gssapi64.dll was not found. Reinstalling the 

program may fix this issue.

Please try the following workaround:

conda install -c conda-forge krb5

This will install a package in your conda environment that may solve the issue. 

2. Cryptic issues with gdal_merge vs gdal_translate

It is possible that some gdal tools (like gdal_translate) will work fine, but others (like gdal_merge) will not work.

Here is a possible workaround:

1. Make sure you are using Anaconda prompt (i.e., not PowerShell)

2. Make sure you are usingan environment with gdal installed, that is located within your user directory

3. Try the following:

   1. Navigate within the anaconda prompt into the directory that has gdal installed:

e.g.

cd C:\Users\dansousa\.conda\envs\NASAEARTH\Scripts

3. 2. Call the gdal_merge script using python, and name each individual input file in the code

e.g.

python gdal_merge.py -of GTiff -o C:\Users\dansousa\Desktop\test\test_mosaic.tif -n 0 C:\Users\dansousa\Desktop\test\p04_ir3_mosaic04.tif C:\Users\dansousa\Desktop\test\p06_ir3_mosaic04.tif C:\Users\dansousa\Desktop\test\p09_ir3_mosaic04.tif C:\Users\dansousa\Desktop\test\p11_ir3_mosaic04.tif
