I am now separating my public scholarship to keep this blog focused on GIS-related topics. I continue blogging critically about the COVID pandemic response at https://clausr2020.substack.com/. My other web and social media sites can be found via https://linktr.ee/clausr.

Scale is one of the most fundamental concepts in Geography. My PhD student just completed her dissertation on “The Consequence of Scale: Process and Policy Implications of Composite Index Modelling Using the Conceptual Framework of GIS-MCDA”, in which she compares biodiversity indices computed at different scales within a city, for example smaller census tracts vs larger social planning neighbourhoods. In Geographic Information Systems (GIS), we usually work with aggregated data, and the scale of aggregation can range from census blocks through postcode areas and neighbourhoods/wards to cities, counties, provinces, and countries. Results of data analytics are known to depend on several aspects of scale, including the observation/measurement scale, at which data are collected; modelling scale, at which data are analyzed; and operational/policy scale(s), at which decisions are made and implemented.Continue reading “Issues of Scale in the Corona Crisis”
Much like many economic, social, health, crime, and environmental data sets, election results have an important geospatial component. For the 2019 federal election, Canada was divided into 338 electoral districts, each of which is represented by a member of parliament. Consequently, thematic maps – usually representing the “first-past-the-post” winning party – are a typical part of news media coverage of the 43rd election. The following examples were found in select Canadian media outlets on the morning after the election.Continue reading “Canadian News Coverage of #elxn43 – The Good, the Bad, and the Ugly Maps”
For GIS Day 2016, the Department of Geography and Environmental Studies joined forces with Environics Analytics, “Canada’s premier marketing and analytical services company”. This year’s Environics Analytics User Conference on November 16 attracted 675 data analysts from 350 organizations and featured 16 client presentations, numerous software demos, and one great party!
The core role of Geography and location in data analytics was emphasized by many presenters. Environics Analytics founder and president, @statslady Jan Kestle, is quoted with identifying “Geography as the secret sauce” that integrates data for advanced analytics. The Department of Geography and Environmental Studies at Ryerson University received shout-outs and accolades for training the next generation of data analysts through its BA in Geographic Analysis and MSA in Spatial Analysis programs.
We joined the Environics Analytics User Conference with a GIS Day-themed display of geovisualization projects from the MSA cartography course and with a 15-year reunion to celebrate the 2001 class of MSA graduates, the first-ever group of students receiving a graduate degree from Ryerson University. Since then, over 300 students have obtained the MSA degree and joined the ranks of data analysts, who shape the regional economy, public services, and environment.

Innovation in higher education and scholarly research has always been a hallmark of the Department of Geography and Environmental Studies at Ryerson. Recent faculty and student achievements underline our position as a social innovation powerhouse on campus.
In the competition for “RECODE at Ryerson University” grants, @RyersonGeo faculty are leading three of the eight successful applications. That is 37.5% of these social innovation projects across campus, a proportion even more impressive if you consider the competitive process with eight grants selected among 33 applications, a success rate of only 24%.
With her RECODE grant, Dr. Claire Oswald, in collaboration with Dr. Claus Rinner and 3D printing startup company Think To Thing, plans to use “A 3D elevation model of Toronto watersheds to promote citizen science in urban hydrology and water resources”. Undergraduate students from our Geographic Analysis and Environment and Urban Sustainability programs will help with processing geospatial data to create a tangible model of the Don River watershed. The model is to be used for school and community outreach on pressing urban water issues.
Dr. Richard Shaker received a RECODE grant for “A prototype for reaching sustainability through local business improvement initiatives: Roncesvalles Village”. In collaboration with the Roncesvalles Business Improvement Area in Toronto, Dr. Shaker’s team will develop metrics of sustainability of local restaurants to support sustainable community planning and management.
The goal of Dr. Andrew Millward’s proposal is to advance “The Citytrees Project: a tool of social innovation that engages people to work collectively and make our cities greener and more resilient”. RECODE funding will assist with forming new community partnerships and collecting tree data with GPS in collaboration with the Toronto Parks and Trees Foundation.
In addition to the faculty grants, our students were equally active and successful in applying for funding from the RECODE student competition.
Jennifer Fisher, a student in our BA in Environment and Urban Sustainability, received a grant to create “Soul Roots”, an urban agriculture project that employs “alternative farming practices to create large yield crops on a contaminated land site”. Working with Provincial and municipal partners in Toronto’s Parkdale community, the project also aims to demonstrate the social and economic impact of local food production.
Sarah Brigel, another student in the EUS program, is using RECODE funds to develop a pilot for her “Microbe-Hub Campus Compost Initiative”. The project aims to divert all organic waste from the Faculty of Arts’ Jorgenson Hall 14-storey building using a closed-loop vermicomposting system.
Another playing field for social innovation made @RyersonGeo is the Faculty of Arts’ SocialVentures Zone. Of the seven student-led social enterprises currently being incubated in the Zone, two were founded by our students, including Jennifer’s “Soul Roots”.
The other SocialVenturesZone project is Claire Stevenson-Blythe’s “Reciprocity”, an app-based platform to help people with signing up for local environmental volunteer opportunities. Claire’s enterprise is focused on engaging active citizenship and sharing solutions for the sustinability issues of our time.
Geography in its analytic, applied, and urban-focused form practiced at Ryerson is destined to inspire and train future social innovators and sustainability leaders. Stay tuned for more news!

Geography@Ryerson is different. Atlases, globes, and Google Maps are nice pastimes, but we are more interested in OpenStreetMap, CartoDB, and GeoDA. We map global flight paths, tweets, invasive species, and shoplifters. As a student in Geographic Analysis you will gain real-world, or rather real-work, experience during your studies. This degree is unique among Geo programs in Ontario, if not in Canada, for its career focus.

The BA in Geographic Analysis has a 40-year record of placing graduates in planning and decision-making jobs across the public and private sectors. Jobs include Data Technician, Geographic Information Systems (GIS) Specialist, Geospatial Analyst, Mapping Technologist, GIS Consultant, Environmental Analyst, Market Research Analyst, Real-Estate Analyst, Crime Analyst, and many more. You name the industry or government branch, we’ll tell you what Geographers are doing for them. And these jobs are secure: Many are within government, or, if they are in the private sector, they tend to be in units that make businesses more efficient (and therefore are essential themselves!).
And these are great jobs, too. In November 2013, GIS Specialists were characterized as a low-stress job by CNN Money/PayScale. There were half a million positions in the US, with an expected 22% growth over 10 years, and a median pay of US$53,400 per year. In their previous survey, Market Research Analysts had made the top-10, with over a quarter million jobs, over 40% expected growth, and a median pay of US$63,100. The 2010 survey described GIS Analyst as a stress-free job with a median salary of US$75,000.
Mapping Technologist, one of Canada’s best jobs!
(Source: Canadian Business, 23 April 2015)
Closer to home, in April 2015 Canadian Business magazine put Mapping Technologists among the top-10 of all jobs in Canada! They note that “The explosion of big data and the growing need for location-aware hardware and software has led to a boom in the field of mapping”. With a median salary of CA$68,640, a 25% salary growth, and a 20% increase in jobs over five years, “this class of technology workers will pave the way”. According to Service Canada, “Mapping and related technologists and technicians gather, analyze, interpret and use geospatial information for applications in natural resources, geology, environment and land use planning. […] They are employed by all levels of government, the armed forces, utilities, mapping, computer software, forestry, architectural, engineering and consulting firms”. Based on the excellent reputation of our program in the Toronto area, you can add the many jobs in the business, real-estate, social, health, and safety fields to this list!

While you may find the perspective of a well-paid, laid-back job in a growing field attractive enough, there is more to being a Ryerson-trained Geographer. Your work will help make important decisions in society. This could be with the City of Toronto or a Provincial or Federal ministry, where you turn geospatial data into maps and decision support tools in fields such as environmental assessment, social policy, parks and forestry, waste management, immigration, crime prevention, natural resources management, utilities, transportation, … . Or, you may find yourself analysing socio-economic data and crime incidents for a regional police service in order to guide their enforcement officers, as well as crime prevention and community outreach activities. Many of our graduates work for major retail or real-estate companies determining the best branch locations, efficient delivery of products and services, or mapping and forecasting population and competitors. Or you could turn your expertise into a highly profitable free-lance GIS and mapping consultancy.
Geography is one of the broadest fields of study out there, which can be intimidating. Geography@Ryerson however is different, as we provide you with a “toolkit” to turn your interest in the City, the region, and the world, and your fascination with people and the environment, into a fulfilling, secure, laid-back, yet meaningful job!
A walk on the beach along the still-frozen Georgian Bay has helped me sort some thoughts regarding fast food cartography, quick-service mapping, and naturally occurring vs. artificial lines in the sand … but first things first: This post refers to a debate about Twitter mapping and neo-cartography that is raging on blogs across the planet and will flare up in the Geoweb chat on Twitter this Tuesday, https://twitter.com/hashtag/geowebchat. Update: #geowebchat transcript prepared by Alan McConchie available at http://mappingmashups.net/2015/04/07/geowebchat-transcript-7-april-2015-burger-cartography/.
A few days ago, The Atlantic’s CityLab published an article entitled “Why Most Twitter Maps Can’t Be Trusted”, http://www.citylab.com/housing/2015/03/why-most-twitter-maps-cant-be-trusted/388586/. There have been other cautions that Twitter maps often just show where people live or work – and thus where they tweet. Along similar lines, a comic at xkcd illustrates how heatmaps of anything often just show population concentrations – “The business implications are clear!”, https://xkcd.com/1138/.
The CityLab article incited Andrew Hill, senior scientist at CartoDB and mapping instructor at New York University, to respond with a polemic “In defense of burger cartography”, http://andrewxhill.com/blog/2015/03/28/in-defense-of-burger-cartography/. In it, Hill replies to critics of novel map types by stating “The dogma of cartography is certain to be overturned by new discoveries, preferences, and norms from now until forever.” He likens the good people at CartoDB (an online map service) with some action movie characters who will move cartography beyond its “local optima [sic]”. Hill offers his personal label for the supposedly-new “exploratory playfulness with maps”: burger cartography.
The core portion of Hill’s post argues that CartoDB’s Twitter maps make big numbers such as 32 million tweets understandable, as in the example of an animated map of tweets during the 2014 soccer world cup final. I find nothing wrong with this point, as it does not contradict the cautions against wrong conclusions from Twitter maps. However, the rest of Hill’s post is written in such a derogatory tone that it has drawn a number of well-thought responses from other cartographers:
- Kenneth Field, Senior Cartographic Product Engineer at Esri and an avid blogger and tweeter of all things cartography, provides a sharp, point-by-point rebuttal of Hill’s post – lamenting the “Needless lines in the sand”, http://cartonerd.blogspot.co.uk/2015/03/needless-lines-in-sand.html. The only point I disagree with is the title, since I think we actually do need some lines in the sand (see below).
- James Cheshire, Lecturer and geospatial visualization expert at University College London, Department of Geography, supports “Burger Cartography”, http://spatial.ly/2015/03/burger-cartography/, but shows that “Hill’s characterisation of cartography … is just wrong”.
- Taylor Shelton, “pseudopositivist geographer”, PhD candidate at Clark University, and co-author of the study that triggered this debate, writes “In defense of map critique”, https://medium.com/@kyjts/in-defense-of-map-critique-ddef3d5e87d5. Shelton reveals Hill’s oversimplification by pointing to the need to consider context when interpreting maps, and to the “plenty of other ways that we can make maps of geotagged tweets without just ‘letting the data speak for themselves’.”
Extending the fast food metaphor, CartoDB can be described as a quick-service mapping platform – an amazing one at that, which is very popular with our students (more on that in a future post). I am pretty sure that CartoDB’s designers and developers generally respect cartographic design guidelines, and in fact have benefited commercially from implementing them. However, most of us do not live from fast food (= CartoDB, MapBox, Google Maps) alone. We either cook at home (e.g., R with ggplot2, QGIS; see my previous post on recent Twitter mapping projects by students) or treat ourselves to higher-end cuisine (e.g., ArcMap, MapInfo, MAPublisher), if we can afford it.
I fully expect that new mapping pathways, such as online public access to data and maps, crowdmapping, and cloud-based software-as-a-service, entail novel map uses, to which some existing cartographic principles will not apply. But dear Andrew Hill, this is a natural evolution of cartography, not a “goodbye old world”! Where the established guidelines are not applicable, we will need new ones – surely CartoDB developers and CartoDB users will be at the forefront of making these welcome contributions to cartography.
While I did not find many naturally occurring lines in the Georgian Bay sand this afternoon, I certainly think society needs to draw lines, including those that distinguish professional expertise from do-it-yourselfism. I trust trained map-makers (such as our Geographic Analysis and Spatial Analysis graduates!) to make maps that work and are as truthful as possible. We have a professional interest in critically assessing developments in GIS and mapping technologies and taking them up where suitable. The lines in the sand will be shifting, but to me they will continue to exist: separating professional and DIY cartographers, mapping for presentation of analysis results vs. exploratory playing with maps, quantitative maps vis-a-vis the map as a story … Of course, lines in the sand are pretty easy to cross, too!
Blog post authored by Claus Rinner and Victoria Fast
In response to a recent lab assignment in GEO441 “Geographic information Science”, 49 second-year Geographic Analysis students selected a crowdmapping application and actively contributed valuable geographic information.
The most popular choice was the global OpenStreetMap initiative (http://www.openstreetmap.org). From updating the name and hours of their favourite restaurant or adding their local bank to a plaza, to identifying community gardens, adding a newly built hospital or geocoding new condos, the students used their local knowledge of the GTA to update and expand the freely accessible OpenStreetMap dataset.
For example, second-year Geographic Analysis student Stephanie Dizonno added a restaurant, George’s Pizza, to a set of businesses already represented along Toronto’s Dundas Street East.
Some of the more unusual edits were made by GEO441 student Kyle Smith, who is a recreational pilot. Kyle corrected and added key features to a local airport, such as a taxiway, the airport restaurant, and the apron, which we learned is the paved area used for aircraft parking. An essential part of his contribution was to update “crucial attribute data about the airport’s characteristics using the Canadian Flight Supplement,” writes Kyle.
In addition to OpenStreetMap, other students elected to contribute to Wikimapia, Cropland Capture, Night Cities, and the David Rumsey Map Collection. For example, instead of the point, line, polygon, and/or attribute data added to OpenStreetMap, the Cropland Capture online game (http://www.geo-wiki.org/games/croplandcapture/) has ‘players’ indicate whether or not a given satellite image includes agricultural land. Mooez Munshi highlights the relevance of his contribution: “The geographic data collected will help in building a map that shows all of the world’s cropland.”
Geographic Analysis student Daniel Bocknek elected to geographically reference a 100-year old map from the David Rumsey Map Collection (http://www.davidrumsey.com/view/georeferencer) showing the Aberfoyle area in Scotland. After identifying at least three control points on both the historic map and a contemporary basemap such as OpenStreetMap or Google Maps, the historic map is automatically geo-referenced and can be integrated with other GIS data as shown in Daniel’s screenshot above.
A similar approach is used by the Night Cities application (http://crowdcrafting.org/app/nightcitiesiss/) to geo-locate photographs of world cities taken at night by astronauts on board the ISS. In his GEO441 assignment, Navdeep Salooja explains that this project involves “citizen scientists”, like himself, in research about global night-time light pollution.
Overall, the 49 Ryerson students contributed important bits (and bytes) to the growing body of volunteered geographic information, while experiencing the broad applicability of geographic knowledge and principles of geographic information science to real-world issues.
Thought Spot is a project designed by post-secondary students to support mental health and wellbeing among Toronto-area youth. The main feature is the online map at http://mythoughtspot.ca/, which is based on the Ushahidi crowdsourced mapping platform. The Thought Spot project was initiated at the Centre for Addiction and Mental Health (CAMH), in collaboration with the University of Toronto, OCAD, and Ryerson. The map allows students to find mental health and wellness resources in their geographic area, without the need for an intermediary (parent, teacher, physician). The mapped information originates from ConnexOntario and Kids Help Phone data as well as data that were crowdsourced from members of the target audience.
Ryerson Master of Spatial Analysis (MSA) candidate Heather Hart took a lead role in designing the Thought Spot map (shown above), bringing unique geospatial expertise to the table of the project’s student advisory board. Through her MSA practicum placement with a different research group at CAMH, Heather got in contact with the Thought Spot team and brought the funding for her own summer position to Ryerson, to devote half of her time to ensuring that the project’s crowdmapping would be successful. Heather’s involvement culminated in co-organizing a Thought Spot hackathon at Ryerson’s Digital Media Zone in October 2014, which led to the ongoing development of a mobile version of the Thought Spot map.
This photo shows Heather at GIS Day at Ryerson on November 19th, 2014, presenting the Thought Spot project to an interested University audience. In collaboration with Environmental Applied Science and Management PhD candidate Victoria Fast, Heather has now also submitted a conference abstract about “Crowd mapping mental health promotion through the Thought Spot project”. The abstract brings together Victoria’s extensive expertise in volunteered geographic information systems and Heather’s on-the-ground experience with the Thought Spot project. Their presentation at the annual meeting of the Association of American Geographers in April 2015 is part of the “International Geospatial Health Research” theme.
It is wonderful to see two enterprising Geography graduate students contribute to supporting mental health and wellbeing on campus, a goal that the University is committed to. At the same time, the Thought Spot project informs Heather’s thesis research on the role of maps in evidence-based health care decision-making and Victoria’s dissertation on crowdmapping of local food resources.
