    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…)

    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
    --
    equatorstudios.com/what-is-a-d <-- 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...”
