For learners considering a career using GIS technology, what do you find most meaningful about researching and teaching in this field?
For me, working in the field of Geographic Information Systems (GIS) is particularly meaningful because it allows us to visualise and analyse spatial data in ways that can directly influence public health and social equity.
For example, recently my research on how vaping stores are distributed across different neighbourhoods in Aotearoa New Zealand has highlighted significant disparities in accessibility, even around our schools, and this can have profound implications for community health. By mapping these locations and analysing their proximity to schools and socioeconomically disadvantaged areas, GIS provides insights that can guide policy decisions and interventions aimed at reducing health risks associated with vape stores for young people.
For learners considering a career in GIS, the most compelling result is the ability to apply these tools to real-world problems, making data-driven decisions that can improve public health outcomes and ensure a more equitable distribution of resources. The interdisciplinary nature of GIS, combining elements of science, technology, and social research, makes it an exciting and impactful field to work in.
Why do we need to learn how to use GIS tools?
Learning how to harness GIS tools to create meaningful data has become increasingly critical in recent years due to the growing complexity of global challenges and the explosion of available data, especially spatial data. Unlike 5, 10, or even 20 years ago, we now have access to vast amounts of data and especially geospatial data, ranging from satellite imagery to real-time data from mobile devices. However, this data is only valuable if we can interpret it effectively to solve real-world problems. GIS tools enable us to analyse and visualise spatial relationships, uncover patterns, and make data-driven decisions that are crucial in fields like public health, environmental management, urban planning, and more.
In today's world, where issues like climate change, pandemics, and urbanisation require swift and informed responses, being able to create actionable insights from GIS data is more essential than ever. For example, understanding the spatial distribution of immunisation coverage can inform public health strategies, while analysing the proximity of green spaces can influence urban planning decisions that promote wellbeing. The need for these skills has never been greater, and GIS offers a powerful way to turn raw data into impactful, evidence-based solutions.
How can this course help learners advance or enter a career that uses GIS mapping software?
Our GIS for Mapping course is designed to be highly practical, equipping learners with hands-on experience in using GIS mapping software, which is essential for advancing or entering a career in this field. The course focuses on real-world applications, to provide students with the skills needed to create, interpret, and use spatial data effectively.
I really enjoy creating maps and working with spatial data, and while the course does cover theoretical concepts to build a strong foundation in GIS principles, the emphasis is on practical skills that can be directly applied in professional settings. By the end of the course, learners will have developed competency to use GIS tools in various industries, including urban planning, public health, environmental management, and more, giving you essential skills for any career that requires spatial analysis.
Image: Mapping vape stores across Aotearoa
The GeoHealth Lab recently published some research that Matt was part of – Breaking Through the Cloud: Vaping in Aotearoa New Zealand. They wanted to understand the spatial distribution of vape stores in Aotearoa New Zealand; where the stores are and how they change over time. Using GIS data and other data, they found about 30% of vape stores are within 400m of a school or kura. But schools in more deprived areas are more likely to have a vape store nearby.
