How would you map the monuments of St. Louis?
Monument Lab

In the summer of 2019, a research project spearheaded by Monument Lab asked St. Louis residents and visitors to draw personal maps of the city’s monuments and important sites. “Some maps celebrate famous sites like the St. Louis Zoo and the statue of St. Louis himself atop Art Hill in Forest Park. Others point to things that have been removed from the landscape, like the mounds built by native Mississippians,” St. Louis Public Radio reports. “Another shows a street map of downtown St. Louis with notations for ‘incidents of racism, from microaggression to racial violence.’” A total of 750 people contributed maps, which you can see at this Flickr gallery as well as on the project website, which has accompanying data and analysis.

Google Adds Colour and Detail to Its Maps

Published on by Jonathan Crowe

Google has added a splash of colour and detail to its larger-scale map layers, using a “color-mapping algorithmic technique” to assign colours to more natural features like forest cover and deserts. “First, we use computer vision to identify natural features from our satellite imagery, looking specifically at arid, icy, forested, and mountainous regions. We then analyze these features and assign them a range of colors on the HSV color model. For example, a densely covered forest can be classified as dark green, while an area of patchy shrubs could appear as a lighter shade of green.” Meanwhile, cities get more pedestrian data, such as crosswalks and sidewalks.

David Cook has released his Illustrative Map of Japan, a hand-drawn pictorial map showing the principal Japanese islands in classic oblique, pictorial-map style. On Reddit Cook says that it took ten years, on and off, from concept to completion: “Conceptually I started in 2010, but actually drawing this version didn’t start until 2012 when I finally settled on a size and perspective. Tbh I did not work on it continuously all those years. The drawn portion wrapped up in 2017 and I didn’t start coloring it in until 2019.” It’ll be available for sale as a 24-by-36-inch print at some point. [r/MapPorn]

Drought Affects One-Third of the United States

One-third of the United States is currently affected by at least moderate levels of drought, NASA Earth Observatory reports.

The map above shows conditions in the continental U.S. as of August 11, 2020, as reported by the U.S. Drought Monitor program, a partnership of the U.S. Department of Agriculture, the National Oceanic and Atmospheric Administration, and the University of Nebraska—Lincoln. The map depicts drought intensity in progressive shades of orange to red and is based on measurements of climate, soil, and water conditions from more than 350 federal, state, and local observers around the country. NASA provides experimental measurements and models to this drought monitoring effort.

According to the Drought Monitor, more than 93 percent of the land area in Utah, Colorado, Nevada, and New Mexico is in some level of drought; 69 percent of Utah is in severe drought, as is 61 percent of Colorado. More than three-fourths of Oregon, Arizona, and Wyoming are also in drought. The effects of “severe” drought include stunted and browning crops, limited pasture yields, dust storms, reduced well water levels, and an increase in the number and severity of wildfires. Most of those areas had no sign of drought in the mid-summer of 2019.

New Approaches to Ethno-Linguistic Maps

Published on by Jonathan Crowe

Back in 2017, Matthew Cooper wrote a post discussing the problems with language maps and outlined some ways to make better maps of language distributions.

One major issue with most modern maps of languages is that they often consist of just a single point for each language – this is the approach that WALS and glottolog take. This works pretty well for global-scale analyses, but simple points are quite uninformative for region scale studies of languages. Points also have a hard time spatially describing languages that have disjoint distributions, like English, or languages that overlap spatially. […]

One reason that most language geographers go for the one-point-per-language approach is that using a simple point is simple, while mapping languages across regions and areas is very difficult. An expert must decide where exactly one language ends and another begins. The problem with relying on experts, however, is that no expert has uniform experience across an entire region, and thus will have to rely on other accounts of which language is prevalent where. […]

I believe that, thanks to greater computational efficiency offered by modern computers and new datasets available from social media, it is increasingly possible to develop better maps of language distributions using geotagged text data rather than an expert’s opinion. In this blog, I’ll cover two projects I’ve done to map languages—one using data from Twitter in the Philippines, and another using computationally-intensive algorithms to classify toponyms in West Africa.

NASA Maps the Damage from the Beirut Explosion

NASA has released a map of the likely extent of damage from Tuesday’s explosion in Beirut.

Synthetic aperture radar data from space shows ground surface changes from before and after a major event like an earthquake. In this case, it is being used to show the devastating result of an explosion.

On the map, dark red pixels—like those present at and around the Port of Beirut—represent the most severe damage. Areas in orange are moderately damaged and areas in yellow are likely to have sustained somewhat less damage. Each colored pixel represents an area of 30 meters (33 yards).

The map is based on data from the European Space Agency’s Copernicus Sentinel program, and was analyzed by NASA’s Advanced Rapid Imaging and Analysis team and the Earth Observatory of Singapore.

Philadelphia Print Shop Reopening This Fall Under New Management

Published on by Jonathan Crowe

The Philadelphia Print Shop (not to be confused with the Denver-based Philadelphia Print Shop West), an antique prints, rare books and maps dealer that closed last December, is back in business. David Mackey has bought the business from Don Cresswell, who founded it in 1982, and is relocating it from Philadelphia’s Chestnut Hill neighbourhood to nearby Wayne. A “COVID-style grand opening” is planned for October. [WMS]

Apple’s Look Around Comes to Japan

Published on by Jonathan Crowe

Ata Distance reports that the Look Around of feature of Apple Maps, which is roughly analogous to Google’s Street View, is now available in the Tokyo, Kyoto-Osaka and Nagoya regions of Japan—it’s presumed that this was intended to coincide with the (now postponed) 2020 Olympics. This is the first implementation of Look Around outside the United States. [9 to 5 Mac/Engadget]

Marie Tharp at 100

Published on by Jonathan Crowe

July 30 marks the 100th anniversary of the birth of pioneering ocean cartographer Marie Tharp, whose seafloor maps provided evidence of continental drift. Columbia University’s Earth Institute is marking the event with blog posts, interviews, workshops and other social media and multimedia activity. See, for example, this overview of her legacy by Marie Denoia Aronsohn and a reprint of Tharp’s own piece, “Connect the Dots: Mapping the Seafloor and Discovering the Mid-ocean Ridge.”

The anniversary probably explains why two books about Tharp, aimed at children, are coming out this year:

Add those to Robert Burleigh’s Solving the Puzzle Under the Sea: Marie Tharp Maps the Ocean Floor (2016), also aimed at young readers, and Hali Felt’s 2012 biography of Tharp (for adults), Soundings, which I review here.

Older posts about Marie Tharp can be found here.

Update, July 30: Suzanne O’Connell at The Conversation: “As a geoscientist, I believe Tharp should be as famous as Jane Goodall or Neil Armstrong. Here’s why.”

Garmin’s Slow Recovery from Last Week’s Ransomware Attack

Published on by Jonathan Crowe

Engadget reports that Garmin’s services are starting to come back online after last week’s ransomware attack:

[I]t looks like things are slowly but surely coming back to life. Yesterday, activity-tracking app Strava confirmed that it was again able to send workout data to Garmin’s Connect service. […] But a quick look at Garmin’s system status page shows there are still plenty of issues across its platform.

Unfortunately, Garmin’s relative lack of communication around these issues means we still don’t know exactly what went wrong or when users can expect things to be back to normal. A few other key services, like registering a new device, are also back up and running, but if you’re still experiencing oddities with your Garmin devices, you’ll have to keep being patient.

Garmin’s FAQ on the outage is not particularly forthcoming.

Previously: Garmin’s Online Services Hit by Ransomware Attack.

Update, 1:48 PM: Garmin has issued a statement confirming that “it was the victim of a cyber attack that encrypted some of our systems on July 23, 2020.” There is no sign that customer data was affected, and they expect a return to normal within a few days. [Engadget]
