Where the Animals Go

Where the Animals Go is a new book by cartographer James Cheshire and graphic artist Oliver Uberti. It highlights the use of technology to track animal behavior illustrated with some beautiful maps and charts. A quote from the book's website gives a nice look into it contents.
These astonishing infographics explain how warblers detect incoming storms using sonic vibrations, how baboons make decisions, and why storks prefer garbage dumps to wild forage; they follow pythons racing through the Everglades, a lovelorn wolf traversing the Alps, and humpback whales visiting undersea mountains.
This is a detail from a map showing the tracks of Elephant Seals equipped with temperature and salinity sensors. They dive deep down into the water, making them great candidates for getting these measurements at various ocean depths.

Here are GPS tracks from 25 baboons near the Mpala Research Center in Kenya. The "sleeping tree" was used when there was a leopard on the prowl.

This one details how warblers fled areas of the southeastern United States in advance of a series of tornadoes. They fled a couple of days ahead of time, meaning that they were able to detect the storms well before our normal weather sensors could.

D.C. Water Atlas

This atlas shows the development of Washington D.C.'s water system.
http://doaks.org/resources/d-c-water-atlas

Here is a quote from the atlas page on Dumbarton Oaks, the project's host institution.
As in so many other cities, water is everywhere in Washington, D.C.—and yet it remains largely invisible to most of us, taken for granted or ignored. But D.C.’s waterways and plumbing shape the civic, social, and even commercial lives of its residents just as much now as in the past: the Anacostia, the Potomac, the C&O Canal, Rock Creek. And the crisis in Flint, Michigan, has shown that the questions of where and how cities find their water have tremendous importance for public health, down to the last pipe.  
Unlike many modern web maps, this one is refreshingly free of the usual over-reliance on interactivity. Most of the maps are a simple click or two away. The menu at the top shows the options.
You can also hover over different areas on the main map to get these options.
After choosing an option, there are sub-maps that can be chosen such as this one for the City Canal.
These sub-maps are simple (not interactive) maps with an information panel in the upper left and the year depicted shown at the bottom. The author, John Dean Davis, scanned a series of historical maps and overlaid them onto the modern city. He included some nice details such as the campus of Dumbarton Oaks.
I'm not sure I would have chosen the blueprint color scheme for these maps. Some of the information is a hard to read but it does make for a nice effect and ties the maps together visually.

To explore this further go to the online atlas.

Landmarks of London

British artist and photographer Martin Thompson has created Landmarks of London.
https://static1.squarespace.com/static/527fb937e4b03df6782b2db7/5549fae5e4b058b787457324/59c15a467131a59e2d02049e/1505843841983/print_lo+res.jpg?format=1000w
The Thames River runs as if it were a straight line through the middle and occupying much of the drawing. The main details are the bridges. They are turned sideways so you see the details as you would approaching from a boat. This creates a strange disorienting effect if you look closely, especially when looking at the waves around the bridge supports and the connections to the riverbanks. The landmarks seem to be an aside-literally. They are also turned sideways so they pop out from the river in each direction. Here is a detailed section.
This work does not appear to be for sale yet and there are not any higher resolution versions on his page. However Ollie O'Brien has some nice higher resolution details on the Mapping London blog, as well as a more detailed write up. This one is turned sideways and shows some of the newer, goofily named buildings.

Prisons of New Jersey

In 1955 the American Prison Association held its conference in Atlantic City. A map of New Jersey's highlights titled New Jersey Invites You to Come and See it All was created to welcome guests.
http://mapmaker.rutgers.edu/NJinvitesYou_1955.gif
These highlights were mostly prisons in their eyes. For example, the nearby Prison Farm at Leesburg.
Sure, there are other things to see in New Jersey like some statue of liberty but check out the Rahway Reformatory.
Washington crossed the Delaware, there's a world-class university but the Trenton Home for Girls is really something!
High Point is one of the few places highlighted that sounds like a nice place for the spouse to visit while you're at the conference.   
Even the roads look imprisoning with the light posts evoking watch towers or fences.
Nothing much to see in this area-except for the Camden County Workhouse.
You can browse the entire map on the Rutgers Mapmaker web site.

Time Maps

Mapbox has created this fantastic "map" - really a diagram showing web search results from the perspective of time, in this case walking time. The map is a concentric circle diagram with geography only preserved in the direction of each result.
In their own words Mapbox has "swept the physical world away completely, in favor of the time needed to move around it." The results are from Foursquare and are somewhat dubious as I will discuss.

I chose Rittenhouse Square in Philadelphia, a favorite spot since childhood. One nice feature was I just put in the name of the square, no city, state or any other info and it knew exactly where to go. I searched for ice cream, often problematic in that neighborhood because places seem to come and go quickly. Click on any spot and you get a walking route with directions.
You can click "Find me" to get your location or start searching an address. The address search is overly eager. I started to enter an address where I'll be going soon in upstate New York and it took me first to Birmingham, UK and then to Toronto before I could finish typing.
Of course, a map like this is only as good as the information behind it. When I did some searches of my neighborhood, I found quite a few businesses that closed several years ago while some places that are well over five years old did not appear.

For some details on how and why see the this Mapbox blog post.

Hurricane Footage from Snap Map

I don't spend much time with social media. As a result, I've been missing one of the bigger map stories of the year, the growth of Snapchat's Snap Map. Hurricanes Harvey and Irma have brought Snapchat to the forefront of media coverage. 
Image via Elite Daily
According to Elite Daily, when Irma made landfall Snapchat received 250,000 submissions within 24 hours. These numbers are way higher than the already high 100,000 daily submissions from Hurricane Harvey. Major media outlets used these pictures and videos in their coverage. The map part of the app is useful to focus on what is happening in specific geographic areas.
Image via Recode
The yellow-red colors in the background show where larger concentrations of posts are geotagged. Zoom in to see more Snapchat pictures and videos. Here's an example via Recode.
Early previews of the mapping function focused on it as a fun way to send your private data to corporations.

Having fun at the club!!!
It's somewhat ironic then that it has become a way to voyeuristically watch people's lives get torn apart by natural disasters.

NOTE: I tried to get Snapchat on my old phone so I could see for myself and get my own images for this post. Unfortunately I do not have enough storage on my phone to download the app. Sorry that I have to rely on second hand images like the ones above instead of providing original content.

Disaster Mapping Help

While Hurricane Irma does some scary stuff and Houston is still bailing out, here is a reminder that anyone can help disaster responders from their desktops through Humanitarian Open Street Map. By identifying roads and buildings from aerial photography, you can help organizations like Doctors Without Borders and the Red Cross find affected people and buildings. No prior mapping knowledge is needed.
In a previous blog post, I talked about my experience helping with the 2015 earthquake in Nepal.
 
There is not yet a mapping project for this year's hurricanes but there probably will be as places recover.

UPDATE:         Now there is!

You can also help with their Malaria Elimination Campaign.  Here is a screen shot of buildings mapped in Zimbabwe so far.
