New census data projects which states could gain or lose congressional seats in 2020 reapportionment

the Census Bureau released its population estimates for 2017 for every state, detailing how many residents each state has gained or lost since the 2010 census. The firm Election Data Services has used these estimates to project how many congressional seats each state might gain or lose in the 2020 round of reapportionment, which assigns each state its share of the House’s 435 districts based on its population.

Reapportionment is a forgotten step.  Before a state can redistrict the congressional districts within the state, every 10 years, the Federal government is constitutionally required to conduct a census with the main goal of being able to reapportion the congressional seats based on the decennial census.  The upcoming 2020 Census is big deal, showing regional population shifts with political ramifications.

USGS’s Streamer Tool

Streamer is a new way to visualize and understand water flow across America. With Streamer you can explore our Nation’s major streams by tracing upstream to their source or downstream to where they empty.

Streamer is the online mapping application that lets anyone explore downstream and upstream along America’s rivers and streams (here is a YouTube tutorial). Streamer can be used to follow the paths of rivers up to their headwaters and down to the sea, to view location-related information such as weather radar and near real-time streamflow data, and to discover hydrologic connections between distant places.

Ventusky – Wind, Rain and Temperature Maps

Animated wind, rain and temperature maps, detailed forecast for your place, data from the best weather forecast models such as GFS, ICON, GEM

With people on the East Coast concerned about the possible trajectories for Hurricane Florence, I think it is the right time to share these two interactive maps: Ventusky and Windy.  In the past, I also shared NullSchool’s  mesmerizing digital globe with wind data and many other options.  Collectively, these my three favorite online visualization of meteorological data.  Any other favorites?  To friends and family in the Carolinas, stay safe.

Identifying Illegal Overfishing

"The vast majority of fishing vessels follow the rules governing fishing – but many are not, and these bad actors can cause a lot of damage. Vessels may take too many fish ­– overfishing – which is causing our fisheries to collapse. Then there is the problem of illegal fishing, which can occur in protected areas, in another country’s waters or on the high seas. This threatens jobs and food security for millions of people, all around the world.

The trouble is, so much of this illegal activity is hidden – it happens out to sea, making it difficult to scrutinize what individual vessels are getting up to. Fortunately, we are now beginning to see what happens after commercial fishing vessels leave port.

The interactive map we created allows anyone in the world with an internet connection to see the activities of the commercial fishing fleet globally."

Damaged and defiant: Hurricane Harvey

Houston holds strong in the wake of devastation left by Hurricane Harvey.

I am sharing these three interactive webmaps of Houston with my mapping courses to demonstrate what is technologically possible.  Texts, charts, pictures, videos, and maps can be seamlessly integrated to present spatial information in an incredibly engaging and accessible manner.  

Houston’s Hurricane Harvey was incredibly impactful but the factors leading to this were also very complex.  These three Story maps lay out:

  1. Houston’s urban ecological context
  2. The geographic origins of Hurricane Harvey
  3. The human stories from Hurricane Harvey

Political Bubbles and Hidden Diversity: Highlights From a Very Detailed Map of the 2016 Election

The Times’s interactive map of precinct results shows that even within partisan strongholds, there are contrary-voting enclaves.

This feature that shows the 2016 election results at the precinct level is astounding, revealing, and a testament to the difficulty of putting all this information together.  The built-in features in this interactive map to explore selected “voter islands” and one-sided places are especially helpful, but much like Google Earth, many people are eager to zoom in to their own neighborhoods.  The article that accompanies the interactive had some excellent case-studies at a variety of scales.  Geography always matters and the maps reveal so many telling patterns.

Five Tips and Strategies on How to Interpret a Satellite Image

What do you do when presented with a new satellite image? Here’s what the Earth Observatory team does to understand the view.

  1. Look for a scale
  2. Look for patterns, shapes, and textures
  3. Define the colors (including shadows)
  4. Find north
  5. Consider your prior knowledge

Aerial photography can be quite beautiful, as can satellite imagery. These are more than just pretty pictures; interpreting aerial photography and satellite imagery is not easy; here is a great article that gives an introduction on how to interpret satellite imagery. With a little training, satellite images become rich data sources (instead of some visually meaningless data).  Using Stratocam, you can explore and tag some of the amazing place on Earth.

Houston’s stories of Hurricane Harvey

“Blue and her team selected 45 stories, each plotted with ESRI’s ArcGIS software on a map of Greater Houston and tied to the exact location where it was first told. The resulting story map of Hurricane Harvey, ‘Damaged and Defiant: Houston Stories,’ was published in the Houston Chronicle in December. The map shows short narratives gathered by Chronicle staffers from people across the area — from Crosby to Kingwood to Katy — each a unique perspective on the storm; told together, they’re the collective account of a city that experienced one of the worst natural disasters in U.S. history.”

These interlinked Houston story maps show some of the key elements of a good story map: 1) strong spatial analytical components, 2) a powerful narrative, 3) rich visuals, 4) solid cartography, and 5) well-sourced information.

The art of making globes

“In the era of Google Maps, who makes a living out of creating globes – by hand? Peter Bellerby, of Bellerby & Co. Globemakers, for one. Headquartered in London, he talks with Martha Teichner about how a desire to purchase a globe led to him becoming one of the masters of the craft.”

Source: www.youtube.com

Yes, these globes are precise archives filled with geospatial data and locational information–however, that pales in comparison to the artistic brilliance of the globes. These hand-crafted globes are truly works of art.  Marvel at the merger of mathematical precision and artistic design that makes a globe such as these a cartographic gem. 

FUTURE WATCHING: Here is the longer video of the Bellerby Globes being produced.
