Structural Features

STRUCTURAL_FEATURES_IN.SHP is a line shapefile that shows the location of known structural features in Indiana. Attributes include the name of the feature (as listed on the paper source maps), a citation to which paper source source map contained the feature, as well as an indicatior of structural movement of each feature. The paper source maps used to construct these data have scales that range from 1:12,000 to 1:500,000 (only one fault trace) with the majority being taken from sources with a scale of 1:63,360 or larger.STRUCTURAL_FEATURES_IN.SHP 是用于展示印第安纳州已知构造要素位置的线要素形状文件（Shapefile）。该数据集的属性字段包含：要素名称（与纸质源地图标注一致）、收录该要素的纸质源地图引用信息，以及表征各构造要素构造运动的指示标识。用于构建本数据集的纸质源地图比例尺范围为1:12000至1:500000（仅包含1条断层迹线），其中绝大多数数据源的比例尺为1:63360或更大。
