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 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...”
