GFPLAIN250m, a global high-resolution dataset of Earth’s floodplains

Identifying floodplain boundaries is of paramount importance for earth, environmental and socioeconomic studies addressing riverine risk and resource management. However, to date, a global floodplain delineation using a homogeneous procedure has not been constructed. In this paper, we present the first, comprehensive, high-resolution, gridded dataset of Earth’s floodplains at 250-m resolution (GFPLAIN250m).

Satellites see the world as a bunch of pixels.  In this recent article in the journal Nature, the authors used a global set of satellite images to create the first global layer of floodplains.  This data is now publicly accessible as a free download (one you can put into ArcGIS after the files are extracted and zipped).

U.S. Counties Vary by Their Degree of Partisan Prejudice

A guide to the most—and least—politically open-minded counties in America

Source: www.theatlantic.com

I would like to start off by saying that I’ve lived in Red America and Blue America, and I love the people and places of both.  This is a fascinating set of maps because it isn’t just about where are the Republicans and Democrats–we’ve all seen those maps.  More important to to me is attempting to discern where people can still see their neighbors as neighbors, even if they strongly disagree politically.  "In general, the most politically intolerant Americans, according to the analysis, tend to be whiter, more highly educated, older, more urban, and more partisan themselves."

Connecticut’s Changing Landscape

“Changing Landscape is a remote sensing-based land cover study that charts landscape changes in Connecticut and portions of New York. It covers the 25-year period from 1985 to 2010 (with in-between dates of 1990, 1995, 2002 and 2006). It includes information on basic land cover, as well as subsidiary analyses of riparian corridor land cover, impervious cover and agricultural field and soil analysis.”

This story map, created with the Story Map Journal application in ArcGIS Online, is a great example of how to use the “Story Action” features.  Story Action features can move the map view to a particular location or change what is being displayed on the main stage of the story map.  These can also be used to navigate to a different section of the a story map.

Here are two excellent Story Maps that use “Story Action” features.  Please take some time to explore both of them and note how these features enhance the presentation of this spatial information:

  1. Connecticut’s Changing Landscape
  2. Damaged and Defiant: Houston Stories
  3. And just for fun, the Cross-Section of elevation along the meridians.

The Man Behind Most of the Ski Maps in America

“The ski trail map at your local mountain was probably painted by James Niehues. Now you can see his life’s work in one beautiful book.”

This new book looks to be a wonderful cartographic coffee table piece.  Good cartography lies at the intersection of rigorous scientific data display and an aesthetic touch of beauty.

Using BatchGeo

"Quick tutorial on using BatchGeo to create a map using your own spreadsheet (Excel) data."

Source: www.youtube.com

BatchGeo is incredibly easy to use mapping platform…think of it as GIS-lite, but only for simple points on a map (no lines or polygons). If you have a spreadsheet full of point data, you can make a map with your own data. You can grab data straight from an online list (like Wikipedia), but you can also use spreadsheets, databases, or any other tab delimited dataset.

Leading the Location Intelligence Revolution

"As GPS devises, sensors, and drones proliferate, the power of location intelligence increases exponentially. This means LI can bring clarity to the most pressing business challenges – even those that at first glance don’t seem location related. Esri has location down to a science – The Science of Where. Examples from the Bavarian Police Department, Switzerland’s largest retailer, Migros, the Port of Rotterdam, and the European Environment Agency, provide just a taste of the broad scope of challenges that can be tackled through the lens of where."

This video is a good demonstration of the value of GIS, geospatial technologies, and locational intelligence.

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.

Source: www.dailykos.com

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.

Source: txpub.usgs.gov

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

Source: www.ventusky.com

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.
