Examples for doing spatial analysis in CSC computing environment.

Geocomputing using CSC resources

This repository contains examples for use of different geospatial applications. Many of the examples are for CSC supercomputer Puhti but may also be helpful for other systems (or your own computer). Please find a list of all geospatial software that is available on Puhti in CSC docs.

Puhti

R

• Overview
• Puhti - serial/array/parallel processing with R.
• R for LiDAR data: lidR and rlas
• Working with Allas data from R
• Reading NLS topographic database geopackage with R

Python

• Overview
• Puhti - serial/array/parallel processing with Python.
• Working with Allas data from Python
• Reading NLS topographic database geopackage with Python
• GRASS multiprocessing from Python
• Routing
• Sentinel data download from Finhub and Scihub using sentinelsat
• STAC, xarray and dask for downloading and processing data
• Zonal statistics in parallel

Other tools

• FORCE
• GDAL
• GRASS
• PDAL
• SNAP graph processing tool gpt

Use cases / longer examples

• GeoPortti share Github repository includes several longer examples of HPC usage.

CSC Notebooks

• Setting up geospatial Python Jupyter environment

Pouta

• Overview: A collection of instructions to setup virtual machines in CSC's cPouta environment for different tools:

• OpenDroneMap as Docker applications - installing other Docker applications would be very similar.
• GeoServer
• PostGIS
• ArcPy
• MetaShape - installing other Desktop tools could be rather similar.

Download

You can download these scripts to any computer using git. To do this, first navigate to the destination folder (in Puhti this could be your project's projappl or scratch folder):

cd /projappl/<YOUR-PROJECT> or cd /scratch/<YOUR-PROJECT>

And then clone this repository there

git clone https://github.com/csc-training/geocomputing.git
