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.

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

Pacific nation Tuvalu has grown by 73 hectares over 40 years

“The tiny Pacific nation of Tuvalu – once thought to be under threat from rising sea levels – has grown the size of California’s Disneyland over the past 40 years. It’s mostly thanks to waves dumping extra sediment, sand and gravel on shore lines, according to research by Auckland University scientists. The study, published in the Nature Communications journal on Friday, was the first in-depth look at how much each of Tuvalu’s 101 islands have changed over the decades.”

See the Strange, Beautiful Landscapes Revealed by Lasers

“Geospatial technologies unearth a world hidden beneath the lush forests of the Pacific Northwest.”

 

If you were to strip a forest of all its vegetation, what would you see? To find out, Washington state’s government is using airplanes equipped with LIDAR technology to scan the state’s heavily-forested ground. What’s being revealed beneath the trees is a spectacular and strange landscape of hidden geology. Old landslides, abandoned river channels, ancient lava flows, and the tracks of glaciers are suddenly visible in stark relief. Tracking the altitude and location of a plane with GPS while it scans the ground with LIDAR yields a highly precise digital elevation map of the Earth’s surface created out of the billions of laser pulses. By uncovering the debris from old landslides, LIDAR can show where future slides may occur.

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.

Alluvial Fans

“When a mountain stream carries a lot of sediment (clay, silt, sand, gravel, cobbles, and boulders) and leaves the confines of the canyon, the sediment is deposited. Over time, this process creates a fan-shaped deposit. The sediment is deposited not because the gradient of the stream decreased, but because the power of the stream dissipates beyond the canyon mouth as the water is spread thin and infiitrates. Many cities are built on alluvium fans, often leading to hazards from flash floods and mudflows.”

In mountainous, interior deserts, the largest settlements are usually not deep in the deserts or on top of the mountains but in that in between space.  Many settlements in Central Asia are built on these alluvial fans

Burn Scars on California’s Wine Country

Devastating wildfires burned through California’s wine country in October 2017, taking several lives and leaving thousands of people homeless. On October 21, the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on the Terra satellite acquired this false-color image of the burn scars left by the Tubbs (upper left), Nuns (center), and Atlas (lower right) fires. Unburned vegetation appears red; burned vegetation appears brown. Buildings, roads, and other developed areas appear light gray and white.”

The Edge of the Plates

“Tomales Bay lies about 50 kilometers (30 miles) northwest of San Francisco, along the edges of two tectonic plates that are grinding past each other. The boundary between them is the San Andreas Fault, the famous rift that partitions California for hundreds of miles. To the west of the Bay is the Pacific plate; to the east is the North American plate. The rock on the western shore of the Bay is granite, an igneous rock that formed underground when molten material slowly cooled over time. On the opposite shore, the land is a mix of several types of marine sedimentary rocks. In Assembling California, John McPhee calls that side “a boneyard of exotica,” a mixture of rock of ‘such widespread provenance that it is quite literally a collection from the entire Pacific basin, or even half of the surface of the planet.'”
