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..."

[this post should not be considered an endorsement of any organisation, but is shared for learning purposes]
“LiDAR or Light Detection and Ranging is an active remote sensing system that can be used to measure vegetation height across wide areas.
This [tutorial] page… introduce[s the] fundamental LiDAR (or lidar) concepts including:
• What LiDAR data are.
• The key attributes of LiDAR data.
• How LiDAR data are used to measure trees...”

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...
