I tried to download a (200 MB image of the moon's geography)[https://sadr-en.nssdc.ac.cn/detail?dataSetId=972277454573928448&dataSetType=personal] and it crashed my laptop. This repo is just me wrapping that in open seadragon. I'll add a link to the live site here once I get permission from the autors.

To run this yourself, first download the image from the link above. Move it from your downloads folder to client/public/media (I also snake-cased the filename because I'm a programmer, sorry)

mv "~/Downloads/The geologic map of the Moon at 1-2.5M scale (pre-proof).jpg" client/public/media/the-geologic-map-of-the-moon-at-1-25m-scale-pre-proof.jpg

Next go to the server directory, install deepzoom and create a dzi from the jpg. This should take a minute or two

# create a virtual env
cd server
python3 -m venv .venv
source .venv/bin/activate

# install deepzoom
git clone https://github.com/openzoom/deepzoom.py.git
cd deepzoom.py
python setup.py install
cd ..

# convert the jpg to dzi
python dzi.py ../client/public/media/the-geologic-map-of-the-moon-at-1-25m-scale-pre-proof.jpg

# go back to project root for next step
cd ..

Next install the node packages and start the client

cd client
npm install
npm run serve

You should now see the project at http://localhost:8080/
