Deformation Map Visualization: ArcGIS Request a Quote   

SqueeSAR™ and DInSAR results are delivered in an ArcGIS shapefile.

Results from SqueeSAR™ analysis are provided in shapefile format (.dbf database), visualized using ArcGIS: a geographical information system capable of managing large geo-referenced datasets.

ArcGIS is used to create maps of the various data fields (average velocity, cumulative displacement, etc.) for the interpretation of ground deformation.

The shapefile contains information about each measurement point (MP), its characteristics and displacement over the time period observed. Information contained in the shapefile includes:

  • CODE:  MP identification code
  • HEIGHT: MP elevation [m]
  • H_STDEV: MP elevation standard deviation [m]
  • VEL: MP average velocity [mm / yr]
  • V_STDEV: MP average velocity standard deviation [mm / yr]
  • COHERENCE: Quality factor (0 to 1)
  • EFF_AREA: MP type (PS or DS)
  • D [yyyymmdd]: MP displacement for each satellite acquisition [mm]
TRE Toolbar for ArcGIS

TRE has designed an ad-hoc toolbar for the import, manipulation and visualization of SqueeSAR™ data in ArcGIS.

The toolbar simplifies the process of: importing data, applying a legend, displaying time series and viewing metadata.

The toolbar, together with the user manual, is provided with every project.
