How to find frequently visited locations from human mobility data?
Posted 1 month ago
One of the main steps in analyzing human mobility is finding the most visited locations of each person. In doing so, most researchers try to find locations where people spend most of their time. Whether we use a GPS tracking or mobile phone dataset, because of the errors pertaining to the underlying technology (e.g., atmospheric […]
Integrating Space, Time and Geography with ArcGIS Insights: A Case Study of COVID-19 Infection Rates in Ontario Public Health Regions From 2020 to 2022

Introduction Tobler’s First Law of Geography “Everything is related to everything else, but near things are more related to distant things” reminds us how geography plays an important role in the spatial pattern of things that we see everyday. However, when it comes to analysis involving human mobility, epidemiology, or any spatial data that contain […]
The Importance of Careful File Naming
Posted 4 months ago
When I was sitting in my courses learning how to use ArcGIS Pro to generate maps and analyze spatial data, I got the obligatory computer science warnings that come in any software course: put some thought into what you name your files. I did my best to take it seriously at the time, but when […]
Visualizing Climate Model Data using Simple Query Tools from ArcGIS Pro and Web-Based Geovisualization Features
Posted 7 months ago
In my recent summer project as a NSERC-USRA student under the supervision of Dr. James Voogt, I was able to gain access to several datasets from Environment Canada that were not yet publicly avalilable, such as the “GEM-SURF (Global Environmental Multiscale Surface)” data. Our project focuses on using both the air temperature and surface temperature […]
Using ArcGIS to Explore Suitable Housing Areas for Students in London
Posted 7 months ago
In my previous project in the third year GIS course with Dr. Jed Long, I completed a housing map using ArcMap, ArcGIS Online, and Story Map that aims to locate all the most accessible housing areas for Western students to live off-campus. Since the basic version of ArcGIS Online doesn’t provide access to the Spatial […]

Introduction For the past few months I had the pleasure to be working with my supervisor to construct a series of 2D thermal composites using ArcMap from a set of 3D images taken by a forward-looking infrared (FLIR) thermal camera in the field. The difficulty of the project comes from the fact that our images […]
Exploring the Solar Rooftop Potential of Wortley Village/Old South in London, Ontario using ArcGIS Pro and LiDAR-derived DSM

Over the weekend in my exploration of ArcGIS Notebooks, I came across this very interesting ArcGIS Pro Lesson by Esri Senior Product Engineer Delphine Khanna. Although it was not related to my initial plan of learning how to use ArcGIS Notebooks, the project happened to use ArcGIS Pro which I had installed a few days […]
Uncovering the Power of Remote Sensing in Micrometeorological Studies
Posted 1 year ago
In my third-year micrometeorology class with Dr.Voogt, we were assigned a course project to work in small groups throughout the term, and each group had to conduct a research project for related to microclimate or micrometeorology. The course covered a wide range of topics such as solar radiation budget, soil microclimates, surface temperatures, etc. For […]
Using an ArcGIS Pro Python Noteboook to display results of a GWR model
Posted 1 year ago
The Built-in Python notebooks feature in ArcGIS Pro is very useful for creating an automated and reproducible workflow for complex analysis. Personally though, my best use of the ArcPy library in ArcGIS Pro has been for a fairly simple purpose – to create multiple maps iterating over a categorical variable’s values. I often find myself […]
