I saw this book on another post - and so went and found a copy at a 2nd hand book shop…
Looking forward to lunches at work with a cup of tea and maybe a couple of rainy Sundays at home…

I have been digging out my old copies of John McPhee's #books, dipping in, remembering what it was like to be a new #geologist, and how it has carried across into #spatial #data, #geomorphology, #geomorphometry, #hydrology, #landcover, #engineeringgeology, #environmentalscience, #landuse, #massmovement and so much more......
This one paragraph reminded me so strongly of that time,, although I cannot of course write as eloquently:
--
"I used to sit in class and listen to the terms come floating down the room like paper airplanes. Geology was called a descriptive science, and with its pitted outwash plains and drowned rivers, its hanging tributaries and starved coastlines, it was nothing if not descriptive. It was a fountain of metaphor—of isostatic adjustments and degraded channels, of angular unconformities and shifting divides, of rootless mountains and bitter lakes..."

As a geographer, by assimilation in a sense, I enjoy the view from an aeroplane's window, natural & engineered landscapes - including, as a hydrologist again by assimilation, of one of those LA's concrete water control structures shown so often in movies involving vehicles driving quickly down them and splashing across standing water in them for no particular reason except the effect...

The Fluvial Geomorphology Equivalent Of ‘Ontogeny Recapitulates Phylogeny’?
--
https://www.usgs.gov/3d-elevation-program <-- USGS’s 3DEP’s open data for elevation

This is a ‘quick and dirty’ visualisation that I made the other day with 3DEP iFSAR data to get a better sense of the fluvial geomorphology up in this area of NE Alaska near Kaktovik/Gordon, it is amazing what pops...
Lay over some hydrology vectors, some of the underlying geology boundaries, etc - and the landforms become much easier to understand in terms of origin and development - the geomorphic/hydrologic/erosional/geologic/vegetative/etc equivalent of biology's “ontogeny recapitulates phylogeny”?

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...”
