Analyzer

Once the Processor has finished processing all interferograms, the Analyzer panel runs time-series analysis on the resulting products.

Initializing the Analyzer

Once all submitted jobs have finished and show SUCCEEDED in the Processor panel, open the Run Analyzer tab within the same job folder. Select an analyzer type (e.g. Hyp3_SBAS) from the drop-down and click Init to initialize the analyzer workspace. This prepares the configuration and directory structure needed to run time-series analysis on the downloaded interferograms.

Analyzer Panel — The Run Analyzer tab — select an analyzer type and click Init to get started.

Once initialization is complete, an Analyzer tag labeled with the analyzer you chose (e.g. Hyp3_SBAS) will appear on the job folder. Click that tag to open the Analyzer panel and proceed with configuration and processing.

Configuration

Once you enter the Analyzer panel, you can select the steps you want to run for time-series analysis. To adjust analysis parameters, click Change Config to switch to the configuration tab, where each analyzer type (e.g. Hyp3_SBAS) has its own independent settings that are saved separately.

For a full description of all analyzer parameters and options, see the Analyzer Reference.

Running Steps

Select the steps to run and click Run. Steps run sequentially and progress is shown in the log.

Analyzer Running — Analyzer running all steps.

Edit Network

After initializing the analyzer and running at least the load_data step, an Edit Network button appears in the Analyzer panel. Click it to open the network editor showing the interferogram network currently loaded into MintPy, with coherence values overlaid on each edge.

Unlike the pair selection stage, you cannot drag to create new pairs here — the interferograms have already been processed, so only the downloaded pairs are available. What you can do:

Click an active edge to remove that pair from the network
Click a removed edge to re-add it
⚙ Parameters — configure MintPy modify_network constraints and click Run modify_network to let MintPy automatically filter the network

Edit Network Graph — The network editor showing coherence values on each edge. Click an edge to remove or re-add it.

Parameter	Description
Max temporal baseline	Remove pairs exceeding this temporal separation (days)
Max ⊥ baseline	Remove pairs exceeding this perpendicular baseline (m)
Start date	Exclude acquisitions before this date (YYYYMMDD)
End date	Exclude acquisitions after this date (YYYYMMDD)
Exclude dates	Space-separated list of individual dates to drop (YYYYMMDD)
Coherence-based	Enable coherence-based network modification (`yes` / `no` / `auto`)
Min coherence	Minimum average coherence threshold for keeping a pair
Keep min span tree	Preserve the minimum spanning tree when removing low-coherence pairs

modify_network Parameters — The ⚙ Parameters dialog for modify_network configuration.

After running, the graph refreshes to reflect the updated network. You can then continue running subsequent analyzer steps on the modified network.

Overview

After running the reference_point and quick_overview steps, an Overview button appears in the Analyzer panel. Click it to open the Overview drawer, which lets you plot MintPy diagnostic layers directly on the map.

Overview Dark — The Overview button and diagnostic layer controls in the Analyzer panel.

The Overview drawer provides four diagnostic layers:

Button	File	What it shows
Avg Spatial Coherence	`avgSpatialCoh.h5`	Per-pixel average coherence across all interferograms — high values indicate reliable pixels
Avg Phase Velocity	`avgPhaseVelocity.h5`	Mean phase change rate — a quick sanity check for coherent deformation patterns
Unwrapping Error Count	`numTriNonzeroIntAmbiguity.h5`	Number of triangle closures with non-zero integer ambiguity — high counts indicate unreliable unwrapping
Connected Component Mask	`maskConnComp.h5`	Pixels that belong to a connected unwrapping component — isolated pixels are masked out

Click any button to overlay that layer on the map. Click again to hide it. Hover over the map to read the pixel value in the colorbar.

Viewing Results

Once the velocity and geocode steps have completed successfully, a View Results button appears in the Analyzer panel. Click it to open the Results viewer, which overlays the computed velocity map on the main map.

Click any point on the velocity overlay to extract and display the displacement time series at that location.

For more details on the Results viewer, see the Results Viewer page.

Cleanup

Click Cleanup to free disk space after analysis. This removes the temporary working directories (tmp/ and clip/) and any .zip archives in the job folder that were extracted during processing. MintPy outputs, and configuration files are preserved.
