Historical GC-Net AWS photo archive

This repository contains a compilation of photos from the historical GC-Net AWS deployed by K. Steffen and his team between 1990 and 2022.

Purpose:

- repository of photos giving visual evidence of e.g., the relative instrument placement, how much the station is leaning, etc.

- It's ideal to have photos from different vantages and before/after maintenance. So, 4 pix per site / year is a nice-to-have.

Structure:

The dataset is divided in the following folders:

- curated_archive_of_GC-Net_AWS folder.

This is the most important folder. It contains a currated selection of pictures from each AWS, if possible pre and post maintenance, and if useful, from differet angles. Importance is given to the visibility of the general geometry of the station. The pictures are *cropped* and *renamed* to increase ease of use. Nameing convention is \"NAME YYYY MM DDx pre/post via photographer.format\", e.g. \"CP1 1998 05 30a pre via J Box.jpg\".

- all pictures GC-Net folder:

This folder contains all the available pictures from the AWS. No removal of redundant pictures, no cropping, no renaming. Pictures are organized in year and station specific folders.

- The script GC-Net_photos_availibility.py produces an overview plot of the availability of the pictures through the lifetime of each AWS.

- The script make-gif.py goes through a list of given stations and compile all available pictures of it in  the curated folder into a gif.
