==== Sentinel-1 ====
{{ :pasted:20181130-022341.png?600&direct}}
<blockquote>
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.

==== COSMO+SAOCOM ====
<blockquote>
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.

=====REST comm=====
exposed contract values are presented in the [[http://anonette.net:3000/explorer/|explorer]] along with their Curl example,\\ note that no authentication is used

  http://anonette.net:3000/explorer/

\\ 
\\
use [[https://httpie.org|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 [[https://hyperledger.github.io/composer/v0.19/reference/rest-server|composer-rest-server]]
