Installation

pip

pip install insar-eventnet

From source

Clone the repository

git clone https://github.com/asfadmin/AI-Event-Monitoring.git

Activate the conda environment from the environment.yaml file

conda create env -f environment.yaml
conda activate insar-eventnet

then, install the insar-eventnet package and cli

pip install .

Setup

Run the setup command in your desired working directory

insar-eventnet setup

This will add the data directory which is structured like this

data/
      └──input/
        └──products/
        └──aoi/
      └──working/
        └──real/
        └──synthetic/
      └──output/
        └──models/
        └──mask/
        └──tensorboard/

You should now be ready to run everything.

Command line interface

There are two command line interfaces, inference.py which utilizes the cloud API for inference, and insar-eventnet which runs the models locally.

Running Unit Tests

Currently, test coverage is limited. However, they can be run with pytest by simply typing:

pytest

in the root of the project directory.

Synthetic Interferograms

Synthetic Interferograms are generated using more simple math than the simulated ones. This means that the datasets can be created more quickly; although, the simulated interferogram generation is still fairly quick and recommended over this.

Synthetic Masked/Wrapped Pair Example

Simulated Interferograms

Simulated Interferograms are comprised of simulated deformation using Okada's model, simulated turbulent atmospheric error using a FFT method, simulated topographic atmospheric error, and simulated incoherence from turbulent atmospheric error. Most of the functions related to the simulation come from this project by Matthew Gaddes which was used for this 2019 JGR:SE paper.

Basic Model's Mask Examples

These results come from a basic model trained on a simulated dataset with 1000 samples, 900 for training and 100 for validation.
