A ‘Waylaid' Teaching Diorama – USGS “Geology For Land Use”
--
For about 3 years, this gorgeous diorama has ‘just’ been sitting in a corner of a (common) hallway.
I can’t help but wonder its history:
• What prompted its creation?
• Who was the artisan (truly!) that created it and used those components and focus?
• When was it created? (late 1960s as an educated guess????)
• Why was it seen as useful / in what setting? (as I am sure it was)
• How was it funded?
(never mind that I want to claim it for my office, space notwithstanding…)

“This tool visualizes near real-time (NRT) satellite-based fire perimeters, active portions of fire perimeters (fire lines), and active fire pixel detections for the current year.
Use the bottom panel to select different date ranges or subset fires by size, duration, or intensity. Click on an individual fire to visualize the time series of fire growth every 12 hours and create video outputs in GIF or WebM formats.
These fire tracking data are from the Fire Event Data Suite (FEDS) algorithm. Find out more:

Permafrost Formation In A Meandering River Floodplain
--
https://doi.org/10.1029/2024AV001175 <-- shared paper
--
“... KEY POINTS:
• River meandering resets permafrost development and vegetation succession by eroding old floodplain areas and depositing new land
• On the Koyukuk River, permafrost rapidly forms in new deposits, but it takes over 4 Kyr to develop to its full areal extent of 85%
• The rate of permafrost formation is likely linked to vegetation succession on younger and overbank deposition on older floodplain areas…”

"This coloring book was assembled using high resolution topography data from the United States Geological Survey’s 3D Elevation Program to create detailed contour maps for each US State and the District of Columbia.
Each State's contour interval (the vertical distance between elevation lines on a map) was selected to preserve the topographic details the State’s inhabitants know and love. Specifically major mountain ranges and river valleys."

Fluvial System Block Diagrams

I was looking to understand a fluvial system the other day, up in the high Arctic, as I looked at 3DEP remote sensed elevation data… I have always been fascinated by the how geology, water, weather shapes a landscape, including erosion (aka geomorphology if you will) – and realized how very much value fluvial block diagrams have as we try to conceptualise what has, is and will happen(ed.)

What Is A Digital Elevation Model (DEM)?- A Practical Guide
--
https://equatorstudios.com/what-is-a-digital-elevation-model-dem <-- shared tutorial
--
“A Digital Elevation Model (DEM) is a digital cartographic dataset that represents a continuous topographic elevation surface through a series of cells. Each cell represents the elevation (Z) of a feature at its location (X and Y). Digital Elevation Models are a “bare earth” representation because they only contain information about the elevation of geological (ground) features, such as valleys, mountains, and landslides, to name a few. They do not include any elevation data concerning non-ground features, such as vegetation or buildings...”
