What is MoSARt?

The Morphology from SAR toolbox (MoSARt) is a set of python scripts to retrieve morphology changes from SAR amplitude images.

The user needs to provide a set of coregistered amplitude images and a Digital Elevation Model in radar coordinates, the user can also provide longitude and latitude datasets to georeference the results.

Standard Installation (without coregistration workflow)

We recommend using Anaconda or Miniconda to create an environment in which to install MoSARt to prevent dependency conflicts.

conda create -n mosart python=3.12
conda activate mosart
conda install gdal
python -m pip install mosart

Full Installation

MoSARt provides functions to coregister images from ALOS-1 and Sentinel-1 images (bursts). To run these functions the user needs to install hyp3-isce2.

git clone https://github.com/ASFHyP3/hyp3-isce2.git
cd hyp3-isce2
git checkout tags/v2.0.0
conda env create -f environment.yml
conda activate hyp3-isce2
python -m pip install -e .
python -m pip install mosart

Obtain elevation changes:

This repository contains two examples using ALOS-1 and Sentinel-1 images that illustrate the full workflow retrieving elevation changes for the 2008 Okmok caldera eruption and the 2016--2017 Bogoslof eruption.

Important

If you want to run these examples you should install jupyterlab.

conda install jupyterlab

MoSARt was used to retrieve the elevation changes in the 2019-2020 Shishaldin eruption:
