NCSU GIS 595-601: Tools for open geospatial science


The course will cover emerging field of open science and will deal with reproducibility and replicability challenges of computational research. The students will gain a hands-on experience with tools used by scientists to create geospatial research which can be validated by the wider geospatial community. Several geospatial open source tools will be discussed in connection with general-purpose and text authoring tools such as next generation interactive documents and revision control tools. Although the focus of the course is open science, many of the tools used in the course are used in the industry. The course will cover how open source communities and software development process work and how to apply this for research in a lab group. Students will have an option to participate in writing a collaborative publication covering the course topics.

Assignments are always due the next week at the end of the day on Wednesdays, but it is recommended to finish them the following day which is, for most of the days, intentionally left free.

Exception to the above are the assignments from the last week of classes which are due on July 29.

Relevant conferences to keep an eye on: FOSS4G and FOSS4G NA (open source geospatial software), JupyterCon (project Jupyter), State of the Map US (OpenStreetMap), AllThingsOpen (Raleigh), and AGU (usually includes several sessions related to open).

Office hours (Vaclav Petras): Tuesday 1:30 - 2:30pm and Thursday 1:30 - 2:30pm. Before coming confirm by email the time and date (vpetras).


Several geospatial open source tools such as QGIS and GRASS GIS will be discussed in connection with general-purpose and text authoring tools such as Jupyter Notebooks and Git. Here is a detailed list (subject to change):

  1. Open science
  2. Authorea and Markdown
  3. LaTeX (in Overleaf)
  4. Git, GitHub (Markdown, Overleaf, wiki, Zim)
  5. QGIS
  6. Linux, command line (Bash), SSH
  8. Jupyter (and R Markdown)
  9. Writing GRASS GIS module in Python (alternatives: QGIS, R)
  10. Leaflet and leaflet-rastercoords with gdal2tiles --leaflet (plus OSM)
  11. GDAL
  12. Open source development
  13. Docker (and Vagrant)
  14. Writing and reproducing an open science paper

All the software used in the course is open source, so students can install it on their computers without obtaining licenses from the vendors or through the university. Some free of charge services based on open source software or focused on open science or open source development will be used too.

The following additional tools can be discussed as well:

  • Presentation tools: Reveal.js, LaTeX Beamer, R Markdown
  • Poster tools: Tikz Poster, Beamer poster
  • Image tools: ImageMagic, PIL, Graphviz
  • Text tools: Pandoc
