Thanks to a combination of low vaccination rates and the COVID-19 Delta variant, intensive care wards are filling up across the United States. The New York Times maps one of the more disturbing metrics of the pandemic: the percentage of occupied ICU beds by hospital region.

A Flurry of New Book Announcements

News about upcoming map books has been thin on the ground of late, which is hardly surprising given the havoc the pandemic has wreaked on the publishing industry as a whole. But in just the past two days we’ve seen three significant new book announcements.

Kenneth Field’s long-awaited Thematic Mapping: 101 Ways to Visualise Empirical Data, which takes as its starting point a map of a single event—the 2016 U.S. presidential election—will be out from Esri Press as an ebook on the 31st of August, Ken announced yesterday. Pre-order: Amazon (Canada, UK).

You might remember James Cheshire and Oliver Uberti’s amazing 2016 book Where the Animals Go. Their next book of data visualizations, Atlas of the Invisible, will be out in September from Particular Books in the U.K. and in November from W. W. Norton in North America. Pre-order: Amazon (Canada, UK), Bookshop.

The Quarantine Atlas: Mapping Life under COVID-19 is the byproduct of CityLab’s 2020 project soliciting hand-drawn maps of life under quarantine (previously here and here). In the book version, Laura Bliss matches 65 of those submissions with original essays. Due out in April 2022 from Black Dog & Leventhal. Pre-order: Amazon (Canada).

I’ve updated the Map Books of 2021 page with these books; that page still looks awfully sparse compared with previous years. If there’s a map-related book coming out this year that I haven’t listed, please let me know.

Vaccination Rates in Montreal

Interactive maps produced by Radio-Canada from Montreal Public Health data show where vaccination rates on the Island of Montreal are lagging. The Quebec government’s target is to have at least 75 percent of the population vaccinated. Of the 3,000 sectors on the map, 70 percent have reached that goal for the first dose and 3 percent for the second.

These data are useful in terms of where to target mobile clinics and other vaccination outreach programs. I’d love to see this for other cities in Quebec, especially the one nearest to me: Gatineau’s current rate is relatively low (66.4 percent first dose, 51.2 second dose as of this week) and it’d be revealing to see where the uptake is stronger or weaker.

An Osher Map Library Exhibition Inspired by Cancelled Travel in the COVID Era

C. F. Weiland, Cholera-karte oder Übersicht der progressiven verbreitung der Cholera seit ihrer Erscheinung im Jahr 1817 über Asien, Europa und Africa, 1832. Map, 62 × 73 cm. Osher Map Library Sheet Map Collection.

The latest exhibition at the Osher Map Library and Smith Center for Cartographic Education is deliberately on the nose: Where Will We Go from Here? Travel in the Age of COVID-19 is the Osher’s first crowdsourced exhibition, based in part on more than 140 responses to an online survey about cancelled travel plans and the impact of the novel coronavirus pandemic.

The exhibition is divided into five sections, beginning with an introduction to the mapping of pandemics and diseases, and continuing into four themes that emerged from the types of cancelled or postponed trips our respondents wrote about most frequently: Birthdays, Anniversaries, and Family Milestones; Weddings; Work-Related Travel; and Lost Study-Abroad Experiences. The curators selected stories from the survey and matched personal narratives and reflections about trips not taken to historic maps from our collections. We hope that as you walk through the gallery you will take time to read these personal narratives, and that they provide you with an opportunity to engage in quiet reflection about the challenges you and your loved ones have faced this year, and that you will join us in pondering the question: “Where will we go from here?”

At the end of our questionnaire, we asked participants: “Beyond your canceled travel plans, is there anything else you would like to tell us about how the pandemic has impacted your living and working situations?” We were particularly moved by the honest and thoughtful responses to this question; all responses can be read in a scrolling feed on the monitor at the end of the exhibit.

The physical exhibition opened on 13 May and is open to visitors until 15 October 2021. Free admission with timed tickets; no more than six visitors are allowed in the gallery at any one time. The online exhibition starts here; the sections mixing personal narratives and historical maps can be quite poignant.

The Geospatial Revolution Project: Mapping the Pandemic

A decade after the Geospatial Revolution Project, which explored the use and impact of digital mapping technologies, released its fourth and (apparently) final episode, there’s a new episode focusing on how digital mapping tools were conscripted into the battle against the COVID-19 pandemic. The Project has posted a version of the episode including a live panel discussion afterward on Facebook Live.

CDC Vaccination Maps

Maps tracking the progress of the U.S.’s COVID-19 vaccination campaign at the CDC’s COVID Data Tracker (now) include an interactive county-level map showing first and second doses among 12+, 18+ and 65+ populations and a map of vaccine equity (above): a bivariate choropleth map showing the relationship between vaccination coverage and social vulnerability (housing, vehicle access, general poverty).

U.S. COVID Vaccination Rates and Active Cases

This interactive map compares U.S. COVID vaccination rates with active cases at the county level. Created by McKinsey and Company’s COVID Response Center, it’s a bivariate choropleth map that shows two variables at once. (If this confuses you, the legend helps.) It’s a good way to see where low vaccination rates correlate with lots of COVID cases (red on this map), or high vaccination rates with few cases (teal); the map lets you explore other variables as well.

Mapping Vaccine Hesitancy in the United States

The Centers for Disease Control and Prevention released data and maps showing the estimated rate of COVID-19 vaccine hesitancy in the U.S. on a county-by-county basis. The data is based on a question in the Census Bureau’s Household Pulse Survey that asked respondents whether they’d get a vaccine for COVID-19 once it was available to them. Methodology and datasets here. [Boston.com]

COVID-19 in Los Angeles

The New York Times maps the distribution of COVID-19 cases in Los Angeles. “County officials recently estimated that one in three of Los Angeles County’s roughly 10 million people have been infected with Covid-19 since the beginning of the pandemic. But even amid an uncontrolled outbreak, some Angelenos have faced higher risk than others. County data shows that Pacoima, a predominantly Latino neighborhood that has one of the highest case rates in the nation, has roughly five times the rate of Covid-19 cases as much richer and whiter Santa Monica.”

COVID-19 in the United States: A Map Roundup

Now that vaccines are available, they can be mapped as well. The U.S. Centers for Disease Control’s COVID Data Tracker includes this map of total doses administered in the U.S.; this NBC News county-level map showing the percentage of Americans living within 50 miles of a pharmacy expected to carry a vaccine dates from December and is probably out of date by now. [Maps Mania]

According to a survey, more than a quarter of the U.S. population would not get a COVID-19 vaccine if it was available to them. This number is not evenly distributed: this map from MIT Technology Review, presented as a map showing whether your neighbours want to get vaccinated, reveals the regional pockets of vaccine hesitancy (see above). (What the actual hell, Louisiana?)

Mapping COVID-19 Hospitalizations

The thing that seems to worry authorities most about COVID-19 is its potential to overwhelm hospitals, at which point the mortality rate really begins to shoot up. In March, the University of Minnesota’s Carlson School of Management released the COVID-19 Hospitalization Tracking Project, which maps, on a county-by-county, basis, the percentage of hospital and ICU beds occupied by COVID-19 patients.

Simple COVID Maps Show the Growth in the Positivity Rate

Innouveau’s Corona Status Maps are simple yet effective: they show the rate of positive tests at the national, regional, county or city level, depending on the map. They’re animated and have responsive sliders to quickly show how the positivity rate has changed over time; clicking on a region gives a bit more detail as well. With maps of the Netherlands, Amsterdam, the Hague, Rotterdam, the Netherlands plus Germany, Central Europe and Europe, there’s a distinct emphasis in the maps’ focus. [Maps Mania]

COVID Zones

Rather than applying restrictions across their entire jurisdictions, several authorities are designating zones to target measures to prevent the spread of novel coronavirus where the spread is at its greatest. Maps can quickly indicate not only where COVID is at its worst, but also where restrictions have been put into place. Two examples: New York City (above left) and the province of Quebec (above right). New York’s map is interactive and has an address search, whereas Quebec’s map is spectacularly ungranular: diagonal lines show that a region has more strict restrictions in some areas but not others, but does not map those areas (which are indicated in text).

COVID-19 in Ottawa Neighbourhoods

Ottawa Public Health has partnered with the Ottawa Neighbourhood Study to produce this interactive map of COVID-19 rates in Ottawa’s neighbourhoods. Both the map and its underlying data are subject to many caveats: the differences between rural and urban zones, between where people live and where people are tested, and other factors affecting testing and susceptibility. Most notably, the map is updated only monthly, so the current map (screenshotted above) does not take into account the rapid increase in positive cases over the past week or two as Ottawa entered the second wave.
