The displacement time-series result can be exported as a QGIS-compatible format for visualization via the InSAR Explorer plugin or the PS Time Series Viewer plugin.

1. QGIS with InSAR Explorer#

The InSAR Explorer plugin supports both the GRD format and the shapefile format. For more details, please refer to the InSAR Explorer documentation.

a. Setup#
  1. Download and install QGIS if you have not done so.
  2. Install the plugin: Install within QGIS via “Plugins -> Manage and Install Plugins”, then search for “InSAR Explorer”. Alternatively, download the plugin as a *.zip file from the plugin page, and install it through “Plugins -> Manage and Install Plugins -> Install from ZIP”.
  3. Launch the plugin: Access it from the toolbar or through “Plugins -> InSAR Explorer -> InSAR Explorer”.
b. Usage for GRD files#
  1. Export MintPy results to GRD files using save_explorer.py:
save_explorer.py geo_timeseries.h5 -v geo_velocity.h5 -o geo_maskTempCoh.h5 -o timeseries/
  1. Load data in QGIS: Open one of the exported GRD files, e.g., geo_velocity_mm.h5, in QGIS.
  2. Launch InSAR Explorer and click on any point to plot the time series.

c. Using shapefile#
  1. Export MintPy results to a shapefile using save_qgis.py:
save_qgis.py timeseries_ERA5_ramp_demErr.h5 -g inputs/geometryRadar.h5
save_qgis.py geo/geo_timeseries_ERA5_ramp_demErr.h5 -g geo/geo_geometryRadar.h5
  1. Load data in QGIS: Browse to the *.shp file generated by save_qgis.py and add it to the layer. Then open “View -> Panels -> Layer Styling”, and on the right choose “Fill color -> Edit” and add the command below to color-code the map based on velocity value.
ramp_color('RdBu', scale_linear(VEL, -20, 20, 0, 1))

2. QGIS with PS Time Series Viewer#

The PS Time Series Viewer plugin supports the shapefile format only.

a. Setup#
  1. Download and install QGIS if you have not done so.
  2. Install the plugin: Install within QGIS via “Plugins -> Manage and Install Plugins”, then search “PS Time Series Viewer”. Alternatively, download the plugin as a *.zip file from the plugin page, and install it through “Plugins -> Manage and Install Plugins -> Install from ZIP”.
b. Usage#
  1. Export MintPy results to shapefiles using save_qgis.py:
save_qgis.py timeseries_ERA5_ramp_demErr.h5 -g inputs/geometryRadar.h5
save_qgis.py geo/geo_timeseries_ERA5_ramp_demErr.h5 -g geo/geo_geometryRadar.h5
  1. Load data in QGIS: Browse to the *.shp file generated by save_qgis.py and add it to the layer. Then open “View -> Panels -> Layer Styling”, and on the right choose “Fill color -> Edit” and add the command below to color-code the map based on velocity value.
ramp_color('RdBu', scale_linear(VEL, -20, 20, 0, 1))
