This tutorial builds upon the on the work done in the context of the ESA Cat-1 project “Production of global MERIS MCI composite images for detection of plankton blooms and other events” submitted by Dr. Jim Gower.
Hereafter, we will guide you to implement a "MERIS Algal bloom detection using SNAP" application on Terradue's Cloud Platform, a set of Cloud services to develop, test and exploit scalable, distributed earth data processors.
To run this application, you will need a Developer Cloud Sandbox that can be requested from Terradue's Portal, provided user registration approval.
Log on the developer sandbox and run these commands in a shell:
- Install Java 7
sudo yum install -y java-1.7.0-openjdk- Select Java 7
sudo /usr/sbin/alternatives --config javaThis will show on the terminal window:
There are 3 programs which provide 'java'.
Selection Command
-----------------------------------------------
+ 1 /usr/java/jdk1.6.0_35/jre/bin/java
2 /usr/lib/jvm/jre-1.5.0-gcj/bin/java
* 3 /usr/lib/jvm/jre-1.7.0-openjdk.x86_64/bin/java
Enter to keep the current selection[+], or type selection number:
Select java 1.7 out of the menu options by typing the correct number (here it's 3).
- Install R required packages
Run these commands in the Developer Cloud Sandbox shell:
sudo yum install -y snap
sudo yum install -y miniconda
export PATH=/opt/anaconda/bin/:$PATH
sudo conda install -y -c r r-essentials
sudo conda install -y -c r -c terradue r-rciop
sudo conda install -y -c r -c terradue r-ff- Install this application
cd
git clone git@github.com:ellip-workflows/dcs-snap-algalbloom.git
cd dcs-snap-algalbloom
mvn installRun this command in a shell:
ciop-runOr invoke the Web Processing Service via the Sandbox dashboard providing a start/stop date in the format YYYY/MM/DD (e.g. 2012-04-01 and 2012-04-03).
