Recent years have seen the (re)emergence of programmatic approaches to geographical information science and the de-emphasis of established desktop 'GIS' packages, both in research settings and in the commercial world. This class introduces the Python programming language and the Python geospatial ecosystem to prepare students for conducting research in this new context.
The COVID-19 crisis means that all details are subject to change at any time. Keep close tabs on this page, and on information posted to Blackboard for changes to schedules, etc.

Here's the trimester schedule we will aim to follow. Bolded labs have an associated assignment that must be submitted and contributes the indicated percentage of the course credit. Relevant materials (lecture slides, lab scripts and datasets) are linked below, when available.

Lectures will generally consist of up to an hour of presented material, and up to 30 minutes of more open-ended discussion and Q&A based on the materials and on reading which students will have been expected to do ahead of class. After that we will dive into the associated lab materials.
A really great introduction to Python is provided by this freely available PDF book (also available to purchase), from which readings will be assigned, especially in the first half of trimester.
- Downey A. 2015. Think Python: How to think like a Computer Scientist 2nd edn. Green Tea Press, Needham, MA.
Other useful resources are found online and will be called out in lectures as we proceed. There will probably be readings set from
-
Crickard P, E van Rees and S Toms. 2018. Mastering Geospatial Analysis with Python. Packt Publishing.
-
Westra E. 2016. Python geospatial development 3rd edn. Packt Publishing.
These are both accessible via a university subscription through the library, and PDFs are purchasable for only US$5.
Lab sessions follow the lecture sessions and will cover related practical topics. General directions for the labs are found here. Five sessions have an associated assessed assignment, but you should attend all labs and participate fully to broaden your knowledge of GIScience methods and tools as any of the approaches covered may prove useful for you in other parts of the program. (Note also that a portion of the course credit is for participation in all aspects of the course.)
The final assignment may be organised in pairs or small groups, depending on differing student interests and skillsets.
Most of the lab work will be completed in Jupyter Notebook or similar Jupyter Lab environments. These are good for incrementally becoming accustomed to code, then writing small amounts of code, building up to writing more extensive blocks of code.
When we come to the final assignment it may be more effective to work in an Integrated Development Environment (IDE) such as VSCode or PyCharm and use a version control tool such as git.
All these tools are freely available for all platforms (although there are a few wrinkles and variations between platforms).
- manage, analyse, visualize and present spatial data using a range of programming tools
- configure and manage a computing environment suitable for geographical information analysis 3.automate geographic information analysis workflows
- setup and manage version control for geographical analysis projects
- Specify an appropriate combination of tools and languages suitable for the conduct of any well-defined geographical data management and analysis project
This course is 100% internally assessed. Assessment is based on four lab assignments worth 12.5% of overall course credit each, and a final assignment worth 50% of course credit due in the exam period.

Assessments are submitted electronically via dropbox on Blackboard. I will aim to return coursework within 3 weeks. Extensions should be requested from the SGEES administration office. If you anticipate problems come and talk to me.
All assignments must be handed in by their due dates. Non-submission by the required date will result in a 5% penalty off your grade for that assignment for each day or part thereof that the coursework is late. No submissions will be accepted more than 5 days after the due date.
Computer crash or similar excuses are not acceptable. Save your material and make sure you have something to submit by the due date.
Note that there are also non-assessed lab sessions. These will be important for your ability to complete the final assignment effectively and to your all-around training in GIScience, so it is vital that you take them seriously as part of the course.
The primary mode of communication for the course will be via Blackboard, so please ensure that your contact details there are up to date and are regularly checked (note that Blackboard defaults to your myvuw email address).
Since this is a relatively small graduate class, I expect that it will not be a problem to raise any issues or concerns directly with me, or with the GIS technician.
