The team computed the interferometric difference (interferogram or interferometric SAR) between the post-event image acquired on February 21, 2023 with a pre-event image acquired on February 9, 2023, on the Sentinel-1 ascending (satellite moving north) track 14. The interferometric SAR (InSAR) measures the component of surface displacement in the line-of-sight (LOS) between the ground and the satellite, which is at an angle of about 40 degrees from the vertical and slightly south of due west.</SPAN></P><P><SPAN STYLE="font-weight:bold;">NOTE</SPAN><SPAN>: The line-of-sight displacement (LOS) measurement is relative, and the dataset has not been calibrated to any ground location so there is a bias of the reference level, which is unknown. This data has not yet been validated. This displacement map should be used as guidance to identify areas of significant ground displacement, and may be less reliable over snow-covered and vegetated areas.</SPAN></P><P><SPAN STYLE="font-weight:bold;">Suggested Use:</SPAN></P><P><SPAN STYLE="font-style:italic;">Unwrapped Interferogram (UNW): </SPAN><SPAN>Red colors indicate increasing displacement towards the West, while the Blue areas indicate increasing displacement towards the East</SPAN></P><P><SPAN STYLE="font-weight:bold;">NOTE</SPAN><SPAN>: Small vertical displacements have also occurred, but the primary surface displacements were in the horizontal plane.</SPAN></P><P><SPAN STYLE="font-weight:bold;">Satellite/Sensor:</SPAN></P><P><SPAN>Copernicus Sentinel-1 Synthetic Aperture Radar (SAR)</SPAN></P><P><SPAN STYLE="font-weight:bold;">Resolution:</SPAN></P><P><SPAN>90 meters</SPAN></P><P><SPAN STYLE="font-weight:bold;">Credits:</SPAN></P><P><SPAN>NASA-JPL/Caltech ARIA Team</SPAN></P><P><SPAN>The Sentinel-1 data products contain modified Copernicus Sentinel data (2023), processed by the European Space Agency and analyzed at the NASA Jet Propulsion Laboratory.</SPAN></P><P><SPAN STYLE="font-weight:bold;">Esri REST Endpoint:</SPAN></P><P><SPAN>See URL section on right side of page</SPAN></P><P><SPAN STYLE="font-weight:bold;">WMS Endpoint:</SPAN></P><P><A href="https://maps.disasters.nasa.gov:443/ags04/services/turkey_earthquake_2023/aria_displacement_map_sentinel1_20230221/MapServer/WMSServer" STYLE="text-decoration:underline;"><SPAN>https://maps.disasters.nasa.gov/ags04/services/turkey_earthquake_2023/aria_displacement_map_sentinel1_20230221/MapServer/WMSServer</SPAN></A></P><P><SPAN STYLE="font-weight:bold;">Data Download:</SPAN></P><P><A href="https://aria-share.jpl.nasa.gov:443/20230206_Turkey_EQ/Displacements/Sentinel1/A014_20230209_20230221/" STYLE="text-decoration:underline;"><SPAN>https://aria-share.jpl.nasa.gov/20230206_Turkey_EQ/Displacements/Sentinel1/A014_20230209_20230221/</SPAN></A></P><P><SPAN /></P><P><SPAN /></P></DIV></DIV></DIV> |
