The time intervals between the ALOS-2 acquisitions are up to a year apart, so the accuracy of the DPM may be lower in areas of vegetation, such as in the mountains. Scattered pixels over vegetated areas may be false positives, and a lack of colored pixels over vegetated areas may not mean no damage.</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>Copernicus Sentinel-1 Synthetic Aperture Radar (SAR)</SPAN></P><P><SPAN STYLE="font-weight:bold;">Resolution:</SPAN></P><P><SPAN>30 meters</SPAN></P><P><SPAN STYLE="font-weight:bold;">Credits:</SPAN></P><P><SPAN>Original data ALOS-2 PALSAR-2 Product - JAXA (2021-2023).
