This repository contains the application files and scripts to generate a digital elevation model (DEM) to be used with ROI_PAC, GMTSAR or GAMMA Synthetic Aperture Radar interferometry toolboxes.
While the Geohazards Exploitation Platform hosts this service, you may use it in a sandbox to evolve it to e.g. support additional formats.
To run this application you will need a Developer Cloud Sandbox, that can be either requested from:
A Developer Cloud Sandbox provides Earth Sciences data access services, and helper tools for a user to implement, test and validate a scalable data processing application. It offers a dedicated virtual machine and a Cloud Computing environment. The virtual machine runs in two different lifecycle modes: Sandbox mode and Cluster mode. Used in Sandbox mode (single virtual machine), it supports cluster simulation and user assistance functions in building the distributed application. Used in Cluster mode (a set of master and slave nodes), it supports the deployment and execution of the application with the power of distributed computing for data processing over large datasets (leveraging the Hadoop Streaming MapReduce technology).
This application requires mounting a volume with the SRTM tiles. This can be requested for via the Platform support.
Log on the developer cloud sandbox. Download the rpm package from https://github.com/Terradue/srtm-dem/releases.
Install the downloaded package by running these commands in a shell:
sudo yum -y install srtm-dem-<version>-ciop.x86_64.rpm
Log on the developer sandbox and run these commands in a shell:
sudo yum install numpy scipy Xvfb GMTSAR python-devel pygtk2 python-matplotlib python-imaging rciop
cd
git clone https://github.com/Terradue/srtm-dem.git
git checkout develop
cd srtm-dem
mvn install
Run this command in a shell:
ciop-run
