# OGH2023

Julia teaching materials for the [OpenGeoHub summer school 2023](https://opengeohub.org/summer-school/opengeohub-summer-school-poznan-2023/) in Poznan, Poland.

## Hackathons

I've participated in the OGH2023 hackathons by using Julia (and won 🎉). The notebooks are here:

- `hackathons/ticks.ipynb` (for https://www.ratnaweera.xyz/OpenGeoHub_2023/)

- `hackathons/landcover.ipynb` (for https://www.kaggle.com/competitions/ogh2023)

## Schedule

See the [schedule at pretalx](https://pretalx.earthmonitor.org/opengeohub-summer-school-2023/schedule/).

### Tuesday 29th of August 2023 in Room 18

### 09:00 - 10:30

- Introduction (`ogh_summerschool_julia.pdf`, `intro.ipynb`)

- Differences with other languages (`differences.ipynb`)

- Managing packages (`package-manager.ipynb`)

- Parallel processing (`parallel.ipynb`)

### 11:00 - 12:30

- Geospatial processing in Julia (`juliageo.ipynb`)

- Opening the hackathon files (`ogh2023.ipynb`)

## Prerequisites

Please install Julia either from the [Windows store](https://www.microsoft.com/store/apps/9NJNWW8PVKMN) or follow the instructions for installing Julia with Juliaup [here](https://github.com/JuliaLang/juliaup?tab=readme-ov-file#installation).

Afterwards run the following in a command-line to install the packages used in this session.

`julia -e "using Pkg; Pkg.add([\"GeoDataFrames\", \"Rasters\", \"GeoArrays\", \"GeoInterface\", \"IJulia\", \"Plots\", \"WellKnownGeometry\"])"`

One can also run the same from *within* Julia by starting Julia, typing `]` to enter package mode (the prompt should turn blue) and input:

`add GeoDataFrames Rasters GeoArrays GeoInterface IJulia Plots WellKnownGeometry`

## Usage

Please git clone this repository and run jupyterlab to run these notebooks.

```julia

using IJulia

jupyterlab()  # this will launch a browser window

```

Alternatively, you could run these notebooks interactively in VS Code (with the Julia plugin). After following the steps in prerequisites, one could also use their existing Jupyter installation to open/create Julia notebooks.
