<!-- badges: end -->

Materials for the Hyperspectral session on day three of the [DAAD Summer School](https://jupiter.geogr.uni-jena.de/summerschool/) hosted by University of Jena in August 2019.
Due to the requirement of having the _repo2docker_ config files in the repository root, a standalone repository was created for this session.
Materials of all other session can be found [here](https://github.com/giscience-fsu/daad_summerschool).

This project was created using [holepunch](https://karthik.github.io/holepunch) and [repo2docker](https://github.com/jupyter/repo2docker).

- [apt.txt](https://github.com/jupyter/repo2docker) contains the system dependencies
- [runtime.txt](https://github.com/giscience-fsu/daad_summerschool_hyperspectral/blob/01a5057b9d87aaf63059cfe27703d62c024edbc3/runtime.txt) specifies the date of the MRAN mirror from which packages are installed
- At the time of creation it was not yet possible to specify the R version used (https://github.com/jupyter/repo2docker/issues/245)
- At the time of creation, _holepunch_ was not able to declare system depenencies in the docker image. Therefore, the direct way via `repo2docker` was used.

Binder instances will shut down after 10 minutes of inactivity.

# Usage

Either click on "Launch Binder" or run locally via 

```sh
repo2docker https://github.com/giscience-fsu/daad_summerschool_hyperspectral
```

The latter requires a working installation of `docker`.
