Remotely sensed indicators of peatland hydrological feedbacks
Posted 2 months ago
From Hydrological Feedbacks in Northern Peatlands 2: Peat Depth as a Control on Peatland Resilience (Furukawa et al. 2025) This paper was made possible through the contributions in the data collection, conceptualization and writing phases, of members (past and present) of the Mac Ecohydrology Lab as reflected in the authorship. In particular, I would like […]
How Different Riders Move Through Hamilton: What a Year of Bike Share GPS Data Reveals
Posted 2 months ago
As part of my PhD, I set out to understand how different bike share riders actually move through a city. We often talk about bike share users as if they form a single, homogeneous group. But once you dig into the data, a far more nuanced landscape emerges.
“I’m Only Here Because It’s a Required Course”: The Art of Teaching GIS
Posted 4 months ago
I remember being a second-year student in my introductory GIS class, one of many who begrudgingly took the course as a graduation requirement and nothing more. I did not know what GIS was until my first year of university, and the thought of committing to learning this entire interface, loosely aligned with my career goals, […]
Analyzing Bike Share and Public Transit Integration using GPS and Spatiotemporal Distance Decay
Posted 8 months ago
One of the most persistent challenges in public transportation is the "first-and-last mile" (FM/LM) problem: how riders travel from their trip origin, such as homes or workplaces, to the nearest transit stop, and then from the disembark stop to their final destination. In my recent PhD research, published in Travel Behaviour and Society, I examined how bike share systems can help bridge this gap in Hamilton, Ontario.
GIS in a Professional Capacity

“For the first time, we have a comprehensive and actionable overview of palliative care in Ontario. This Atlas helps us see what’s working, reveals the inequities and gaps that too many patients and families experience, and provides us with the knowledge to change that. If we want to build a health system that truly delivers compassion, dignity, and quality of life at every stage of care, then palliative care must be part of the foundation. With this Atlas, we now have the tools to make that vision a reality for everyone in Ontario.”
Case Study Part 2: Rapid assessment of low intensity wildfire in Central Ontario with UAV
Posted 9 months ago
In Part 1, we used satellite imagery and ground surveys to assess the impact of the relatively small, low intensity early season wildfire SUD008 in Central Ontario. Subsequently, we captured RGB imagery of the study area on May 30, 2025 using a UAV (DJI Mavic Mini 2, SZ DJI Technology, China) to an approximately 1.5 […]
Case Study Part 1: Rapid assessment of low intensity wildfire in Central Ontario with satellite imagery and field surveys
Posted 9 months ago
An early season wildfire (SUD008) started approximately a kilometre east of Giroux Lake on May 13, 2025, burning for about a week before being declared out, with a total area burned of 30 ha (Figure 1). While actively fought and fairly low severity, this fire’s proximity to our other research sites and ability to quickly […]

Computing Catchment Areas for Bus Stops using GTFS Static Data
Posted 1 year ago
In this tutorial, I’ll demonstrate how to compute catchment areas, or network buffers, around transit stops in Hamilton, Ontario, using the ArcPy Network Analyst module and Hamilton Street Railway (HSR) General Transit Feed Specification (GTFS) static data from Open Hamilton. Step 1: Import Required Packages Let’s begin by importing the necessary packages. The urllib and […]
