ERROR when exacting DEMS #35

Thank u again for sharing this wonderful work.

When I use native install step by step, ./scripts/extract_dems_override.sh goes wrong.

Reading DEMs info...
ERROR 1: TIFFFetchDirectory:OmniLRS-main/tmp/ldem_87s_5mpp.tif: Can not read TIFF directory count
ERROR 1: TIFFReadDirectory:Failed to read directory at offset 2522680612

Moving DEMs to OmniLRS-main/assets/Terrains/SouthPole...

So how can I solve it? Is it wrong with data ldem_87s_5mpp.tif?

Thank u so much.

Hum, that's coming from NASA so it should be fine, but sometimes the download fails. One way to do it is to manually download the map and redo the processing on it. You could try the following in the docker:

mkdir tmp
cd tmp
wget https://pgda.gsfc.nasa.gov/data/LOLA_5mpp/87S/ldem_87s_5mpp.tif
gdalinfo ldem_87s_5mpp.tif > ldem_87s_5mpp.info
cd ..
./scripts/extract_dems_override.sh

You'd want to do that at the root of the repository (that's where your shell gets instantiated when the docker is started)

Thank u so much for reply so quickly. It solves, though what I have rerun is the LunarLab which maybe doesnot use this DEM data.
