2019 Ridgecrest, CA Pre-Earthquake Digital Surface Model V2

<p>This dataset includes a suite of pre-seismic, 2-meter resolution optical digital surface models (DSMs) pre-dating the July 2019 Ridgecrest earthquakes. The DSMs were constructed using DigitalGlobe base imagery (©DigitalGlobe 2019) and the open source <a href='https://mjremotesensing.wordpress.com/setsm/'>SETSM software package </a>. DSMs are vertically and horizontally registered to a separate pre-event optical DSM that was registered to ICESat-1 data. The base imagery includes 0.5m and 0.3m panchromatic in-track stereo imagery acquired from the WorldView-2 and WorldView-3 satellites. The generation of this data sets was funded in part by SCEC in cooperation with the U.S. Geological Survey.</p> The naming description of individual DSMs is as follows: <br/><br /> <i>sensor_date _id1_id2_dem_2m-DEM.tif </i> <br /><br />where sensor is the sensor from which imagery was acquired (WV02-WorldView2, WV03-WorldView3), date is the acquisition dates in format YYMMMDD (i.e., 13AUG11), and id1 and id2 are the image identifier numbers provided by DigitalGlobe. <br /><br /> <p><b>NOTE:</b>This dataset covers a different spatial extent, and uses different base imagery than the similar dataset, <a href="https://doi.org/10.5069/G998854C"> 2019 Ridgecrest, CA Pre-Earthquake Digital Surface Model.</a></p>

本数据集包含了一套早于2019年7月Ridgecrest地震的、分辨率为2米的预震期光学数字地表模型（DSM）。这些DSM利用DigitalGlobe的基础影像（©DigitalGlobe 2019）以及开源的<a href='https://mjremotesensing.wordpress.com/setsm/'>SETSM软件包</a>构建而成。DSM在垂直和水平方向上与一个独立的事件前光学DSM进行配准，该DSM已配准至ICESat-1数据。基础影像包括从WorldView-2和WorldView-3卫星获取的0.5米和0.3米的全色波段立体影像。该数据集的生成部分资金由SCEC（加州地震中心）与美国地质调查局合作提供。</p> 单个DSM的命名描述如下：<br/><br/> <i>传感器日期_id1_id2_dem_2m-DEM.tif</i><br /><br />其中，传感器指获取影像的传感器（WV02-WorldView2，WV03-WorldView3），日期为获取日期，格式为YYMMMDD（例如，13AUG11），id1和id2是DigitalGlobe提供的图像标识符号码。<br /><br /> <p><b>注意：</b>本数据集覆盖的地理范围与类似数据集<a href="https://doi.org/10.5069/G998854C">2019 Ridgecrest，加州地震前数字地表模型</a>不同，并使用了不同的基础影像。</p>
