The Concept Of Indigenous GIS
--
Reading a paper (alturl.com/8wte5), they used the specific term ‘Indigenous GIS’ – and I found this intriguing!
As I read it, spatial data collection and analysis was done with a focus on how a tribe or social group might ‘see’ the data, including spatiotemporal....
I look forward to finding out more about what others are working on! – so PLEASE feel free to share any examples that you might have…

[Have some stress and love spatial / remote sensing data? Play on your bedside devices…]
“Landsat satellites capture images of the Earth’s surface. While the sensors aboard Landsat capture a wide range of scientifically useful wavelengths, this collection reveals natural color imagery in the red, green and blue parts of the visible spectrum, as if viewed by the naked eye from 438 miles above the surface. Scenes like these help scientists and communities around the world study our changing planet. #GIS #spatial #mapping #landsat #remotesensing better sleep #sleep #meditate #stress #earthobservation #satellite #imagery #usecase

'Some (TopoBathy) Floodplain Images I Made A Few Years Ago, On The Mississippi R.
--
These are some (topobathy) floodplain images I made a few years ago for a specific usecase – and ‘stumbled’ across them again today, lookin’ for something else…
Every time I look at such things, the (engineering) geologist, geomorphologist, (pseudo) hydrologist, spatial data scientist in me is made happy in being reminded what access we have to (often open) spatial data and the sheer volume of it, and the use cases for which it can be leveraged.
We are lucky professionals…

imagery - Topobathymetric digital elevation model of the Santiam River in the Willamette Valley southeast of Salem, Oregon. The trees and dry land are shown as a lidar point cloud colored based on aerial imagery.
drone photo - oblique - The North Santiam drains from the Cascade Range and through the Willamette Valley foothills where it combines with the South Santiam before joining the Willamette River near Salem. The river in this section has numerous gravel bars and secondary channels and is flanked by agricultural lands and floodplain forests.

Spatial Data – Right At Your Fingertips!

Sometimes when you are working, you realise what a truly long way we have come in terms of readily accessible spatial data…
I am looking at remote sensed data in Alaska, both the imagery and the elevation-derived hydrology, on a pseudo-randomly-selected sand bar that maybe no one has ever stood on, just to the east of Noatak National Park – and yet I can get an excellent sense of the hydrology, sedimentology, geomorphology, even the ecology…
