InSAR Explorer

InSAR Explorer

Description

InSAR Explorer is a QGIS plugin that allows for dynamic visualization and analysis of InSAR time series data. InSAR Explorer supports visualizing outputs of SARvey Open-source research software for InSAR time series analysis.

Installation

Method 1: Download from QGIS Plugin Repository

  1. Open QGIS.

  2. Go to Plugins > Manage and Install Plugins….

  3. In the All tab of the Plugin Manager, type Insar Explorer in the search bar.

  4. Select the InSAR Explorer plugin from the list and click Install Plugin.

Method 2: Install the development version from ZIP file

  1. Download the plugin Repository as ZIP.

  2. Open QGIS.

  3. Go to Plugins > Manage and Install Plugins.

  4. Click on the Install from ZIP tab.

  5. Select the downloaded ZIP file and click Install Plugin.

Usage

  1. Open a vector layer with InSAR time series data.

  2. Click on the plugin icon in the toolbar or go to Plugins > InSAR Explorer.

  3. Click on any point in the map to display the time series data.

Data Structure

The plugin requires a vector file (e.g., a shapefile or geopackage) containing time series data. The file should have the following attributes:

Field Name

Description

velocity or VEL

A field containing the InSAR velocity data.

DYYYYMMDD

Multiple fields for time series data, where YYYYMMDD is the date of the data, e.g., D20190101, D20190201, etc.

Sample data

A sample shapefile containing time series data for testing the plugin is available on Zenodo repository.

Data preparation

The data can be prepared for different software tools as follows:

  • SARvey

    Use the sarvey_export script to export the time series data to a shapefile or geopackage file. For example:

    $ sarvey_export outputs/p2_coh80_ts.h5 -o outputs/shp/p2_coh80_ts.shp

  • MintPy or MIaplPy

    Use the save_qgis script to export the time series data to a shapefile. For example:

    $ mintpy save_qgis timeseries_ERA5_ramp_demErr.h5 -g inputs/geometrygeo.h5

  • StaMPS

    to be added.

Note: if you are an InSAR software developer interested in incorporating data visualization support within InSAR Explorer, please reach out to us.
