Geolocation Characterization Website

Introduction

Level-1B geolocation website for users of NASA/NOAA's remote sensing instruments, primarily GOES-R ABI and GLM. Our goal is to facilitate simple storage, delivery, and exploration of geolocation characterization results.

This is a dummy version of the website. Not all of the code is here. The website is not yet public but some version will be someday. Thank you, beauracracy.

Setup

1. Set up Perl environment:

Make sure you are able to find the following Perl modules.

Chart::Gnuplot
Date::Calc
DateTime
List::Util
Mojo::Pg
Mojo::Pg::Database
Mojolicious::Lite
Mojo::Headers
Text::CSV
Time::JulianDay
Time::Piece

2. Fill the database:

If the database tables do not exist, run the SQL script

psql < schema.sql

Then run the following Perl scripts to fill the tables.

gcstdb_perl/ingest_req.pl

gcstdb_perl/ingest_gcstdb.pl

This should take no more than an hour.

You should see the following tables when you enter PostgreSQL.

gcstdb=> \dt
              List of relations
 Schema |      Name       | Type  |  Owner   
--------+-----------------+-------+----------
 public | g16_ccr_ew      | table | gcstdb
 public | g16_ccr_ns      | table | gcstdb
 public | g16_ffr_ew      | table | gcstdb
 public | g16_ffr_ns      | table | gcstdb
 public | g16_metricsfile | table | gcstdb
 public | g16_nav_ew      | table | gcstdb
 public | g16_nav_ns      | table | gcstdb
 public | g16_ssr_ew      | table | gcstdb
 public | g16_ssr_ns      | table | gcstdb
 public | g16_wifr        | table | gcstdb
 public | g17_ccr_ew      | table | gcstdb
 public | g17_ccr_ns      | table | gcstdb
 public | g17_ffr_ew      | table | gcstdb
 public | g17_ffr_ns      | table | gcstdb
 public | g17_metricsfile | table | gcstdb
 public | g17_nav_ew      | table | gcstdb
 public | g17_nav_ns      | table | gcstdb
 public | g17_ssr_ew      | table | gcstdb
 public | g17_ssr_ns      | table | gcstdb
 public | g17_wifr        | table | gcstdb
 public | req             | table | gcstdb

3. Start Morbo to host the dev website on your local machine:

>>> morbo gcst.pl

This will assign a port 3000. To stop Morbo, you need to Control+C in the running terminal.

4. Start Hypnotoad to host the deployed website:

>> hypnotoad gcst.pl

This will assign a port, defaulting to 8080. It can be different, but for rest of document we will assume 8080.

4a. Tunnel the port: (via PuTTY)

In your PuTTY Configuration window, go to Connection->SSH->Tunnels and fill in the following

Source port: 8080
Destination: machine:8080

4b. Tunnel the port: (via Unix)

Type the command, replacing YOURID and MACHINE

ssh -L 8080:machine:8080 YOURID@MACHINE

4c. View the website:

In any web browser, go to localhost:8080/

4d. Stop Hypnotoad:

>> hypnotoad -s gcst.pl

To test any changes you made to the code while in hypnotoad mode, you will need to stop and restart the hypnotaod session.
