SAR imagery
lithium detection with satellites
Sentinel-1
The Sentinel-1 mission comprises a constellation of two polar-orbiting satellites, operating day and night performing C-band synthetic aperture radar imaging, enabling them to acquire imagery regardless of the weather. sentinel-1

COSMO+SAOCOM
The main difference between the two sensors is the wavelength: 3 cm for COSMO-SkyMed X-band and 23 cm for SAOCOM L-Band. This translates in the fact that while X-band can detect even slight details, L-band is suitable to observe larger objects which would result unclear with X-band. Combining the two is possible to monitor both geometrical objects and small details. e-gos.it

“The Alaska Satellite Facility provides production, archiving and distribution to the scientific community of SAR data products and tools from active and past missions, including the June 2013 release of newly processed, 35-year-old Seasat SAR imagery.”

REST comm
exposed contract values are presented in the explorer along with their Curl example,
note that no authentication is used
http://anonette.net:3000/explorer/
use HTTPie to interact with the REST server, a modern replacment for Curl.
on ubuntu type
sudo apt install httpie
to post from command line use, note we cant set a flagColor without naming a place
http POST http://anonette.net:3000/api/Flagcolor flagColor="pink" place="spodumeneHouse"
other possibilities
http POST http://anonette.net:3000/api/Lithopian name="anoterNewName"
to GET values use
http GET http://anonette.net:3000/api/Flagcolor
on server side the comm is handled by composer-rest-server
