Email digest of all things spatial, remote sensing, and GIS
|
|
|
I’ve been putting together lectures on remote sensing for the fourth Coursera GIS course this week, and apparently it means this newsletter is a little focused on remote sensing and satellite imagery. Did you know that the European Space Agency can detect millimeters of subsidence in land, from space, using radar? That’s pretty amazing to think about, not just from an accuracy standpoint, but the idea of space-based radar, which isn’t new, is super interesting. Still, we have a few other things this week, so hopefully you won’t be bored. If you’re in the United States, have a great holiday weekend and be safe! See you next week.

Instructional Guide for The ArcGIS Book
Esri’s “The ArcGIS Book” was a great example of how GIS has expanded far beyond the desktop. Now they have released a full companion book with exercises and additional content meant for students as well as for teachers who want to guide students through the exercises in the book.

Sentinel-1 satellites combine radar vision / Sentinel-1 / Copernicus / Observing the Earth / Our Activities / ESA
The twin Sentinel-1 satellites have – for the first time – combined to show their capability for revealing even small deformations in Earth’s surface.

Mapping that sinking feeling / Sentinel-1 / Copernicus / Observing the Earth / Our Activities / ESA
For a low-lying, densely populated country like the Netherlands, monitoring subsidence is critical. Until recently, tiny displacements in the ground beneath our feet couldn’t be mapped nationally but, thanks to the Sentinel-1 mission, this is now possible.

GitHub - sat-utils/sat-download: A python library for downloading Satellite Imagery. Currently supports Landsat-8 and Sentinel-2A.
“sat-download - A python library for downloading Satellite Imagery. Currently supports Landsat-8 and Sentinel-2A.” This looks to be a really handy way to save some time when downloading Landsat data!

Accessing Landsat and Sentinel 2 on Amazon Web Services
For those of you who host your websites or data processing at AWS, this is for you - or maybe you just find it faster to access the AWS repositories for this data than the USGS copies (for Landsat).
