Hurricane Laura information and resources, including maps of the observed and forecasted storm track, potential rainfall, storm surge and flooding, and other warning maps, can be found via NOAA’s Laura event page, the National Hurricane Center’s Hurricane Laura page, and the Esri Disaster Response Program’s Hurricane Hub.

Last year saw an uptick in fire activity in the Amazon basin. This year a new tool has been released that aims to help classify the fires being observed. The Amazon Dashboard classifies each fire as a deforestation fire, a savanna fire, a small clearing and agricultural fire, or an understory forest fire, and tracks whether the fire is in a protected or indigenous territory. NASA Earth Observatory:
The fire analysis tool is already bringing new clarity and insight to the 2020 fire season. In July, Brazil announced a 120-day ban on fires in the Amazon rainforest; it was presented as an effort to limit ecological damage from fires this year. However, the NASA-led fire analysis indicates that there has been a proliferation of fires in key deforestation hotspots in the southern Amazon states of Pará, Mato Grosso, and Amazonas.
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 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]
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.
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]
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]
