NCALM. PI: Witold Krajewski, University of Iowa. The two survey areas are both irregular polygons. The first polygon enclosed approximately 282 square kilometers and was centered on the Iowa River from the Coralville Dam just north of Iowa City, Iowa and continuing south. The second polygon enclosed 282 km square and was centered on the Clear Creek Watershed. The data were collected to survey the Iowa River Flood along the Iowa River and Clear Creek Watershed.

NCALM数据集，由爱荷华大学Witold Krajewski教授主持。本数据集涉及两个不规则多边形调查区域。其中，首个多边形围合区域约为282平方公里，以爱荷华州爱城北部的科拉维尔大坝为起点，沿爱荷华河向南延伸。第二个多边形围合区域同样为282平方公里，中心位于Clear Creek流域。数据收集旨在对爱荷华河流域及Clear Creek流域的洪水情况进行调查。数据收集项目得到了美国国家科学基金会小规模探索性研究（SGER）计划的资金支持。<p><br>与该数据集相关的出版物可于<a href="http://calm.geo.berkeley.edu/ncalm/dtc.html" target="_blank">NCALM数据追踪中心</a>查阅。</p>
