Introducing SARscape Analytics ToolboxSupported sensorsAll workflows of the SARscape Analytics Toolbox ingest original SAR data files or imported SARscape raster format.To save processing time, most inputs are in SARscape raster format ( slc / slc list / cut slc / cut slc list),generated during SAR data import by the SARscape software.SensorFormatSensorFormatALOS PALSAR-1img*; *.datICEYE*.h5; *.H5 (preliminary)ALOS PALSAR-2IMG*; *.datRADARSAT-1*.xmlASNARO-2IMG-*1.1 *; IMG-RADARSAT-2DAT*; dat*; *.D; *.dCOSMO-SkyMed*.h5; *.H5RISAT-1product.xml; *.ntfENVISAT ASAR*.N1Sentinel-1*manifest.safeERS SAR*.E1; *.E2SICD*.nitf; *ntfGAOFEN-3*.meta.xmlTerraSAR-X and Tandem-X*.xmlKOMPSAT 5*.h5; *.H5PAZ-1*.xml
Introducing SARscape Analytics ToolboxAn important note on sensor data inputAll input datasets of the workflows Time Series, Flood Mapping, Change Detection, DEM Extraction, Displacement Mapping, Persistent Scatterers,require the following properties: same sensor, same acquisition geometry(Ascending or Descending), same incidence angle, same data type, same polarization.*Martone, Michele. (2019). Onboard Quantization for Interferometric and Multichannel Synthetic Aperture Radar (SAR) Systems. Michele Martone*
Introducing SARscape Analytics Toolbox WikipediaSupported coordinate systemsSARscape supports data in Geographic coordinate system (GCS WGS84), UTM projection.SARscape does not support any other cartographic systems.The output coordinate system is based on DEM coordinate system, which can be Geographic coordinate system (GCS WGS84), UTM projection.

SAR Change DetectionSAR Change Detection Classification RefinementThis tool creates a classification raster that identifieschanges between two images.It performs amplitude and phase analysis.Amplitude analysis uses the intensity of the SAR imagesto track changes over time.Phase analysis uses the coherence, or stability index,between the scenes input to track changes.This workflow can detect subtle changesin the structure of the scene viewed.Data courtesySentinel-1 pre-fire and co-fire images, California, U.S.Filtered change detection map (top)and stability index (coherence) image (bottom)
SAR Change Detection – Result EvaluationExplore the resulting Change Detection MapDisplay the Change Detection Map and evaluate itusing the classification key: Changes (i.e. forest, dense canopy) No changes Significant changes/Reflectivity increment (i.e. water, farming) Significant changes/Reflectivity decrement (i.e. water, farming) Humidity increment (i.e. moisture increase) Humidity decrement (i.e. freezing, drying)
