This map was derived from Synthetic Aperture Radar (SAR) images acquired by the ALOS-2 satellite operated by the Japan Aerospace Exploration Agency (JAXA) before (28 Jun 2022 and 18 Oct 2022) and during the event (29 Nov 2022, 10:23 UTC).</SPAN></P><P><SPAN STYLE="font-weight:bold;">Suggested Use:</SPAN></P><P><SPAN>The color variation from yellow to red indicates increasingly more significant surface change. Preliminary validation was done by comparing with high-resolution optical imagery. </SPAN></P><P><SPAN>This damage proxy map should be used as guidance to identify damaged areas or areas affected by heavy volcanic ash fall, and may be less reliable over vegetated areas. For example, the scattered colored pixels over vegetated areas may be false positives, and the lack of colored pixels over vegetated areas does not necessarily mean no damage. This map is most sensitive to building damage and other large changes, but small-scale change or partial structural damage may not be detected by this map.</SPAN></P><P><SPAN STYLE="font-weight:bold;">Satellite/Sensor:</SPAN></P><P><SPAN>Japan Aerospace Exploration Agency (JAXA) ALOS-2 PALSAR-2</SPAN></P><P><SPAN STYLE="font-weight:bold;">Resolution:</SPAN></P><P><SPAN>JAXA ALOS-2: 25 meters</SPAN></P><P><SPAN STYLE="font-weight:bold;">Credits:</SPAN></P><P><SPAN>Earth Observatory of Singapore - Remote Sensing Lab (EOS-RS), Original data ALOS-2 PALSAR-2 Product - JAXA (2022).</SPAN></P><P><SPAN>Data were provided by JAXA and analyzed by the Earth Observatory of Singapore - Remote Sensing Lab (EOS-RS).</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><SPAN STYLE="font-weight:bold;">Data Download:</SPAN></P><P><A href="https://eos-rs-products.earthobservatory.sg:443/EOS-RS_202211_Hawaii_MaunaLoa_Volcano/" STYLE="text-decoration:underline;"><SPAN>https://eos-rs-products.earthobservatory.sg/EOS-RS_202211_Hawaii_MaunaLoa_Volcano/</SPAN></A></P></DIV></DIV></DIV> |
