Surficial Unconsolidated Thickness Contours

UNCONSOLIDATED_THICKNESS_250k_IGS_IN.SHP is an Esri line shapefile providing a contoured depiction of the thickness of unconsolidated sediments in Indiana. Thickness contours are represented by polylines (50 foot contour interval) each with a single value that provides estimated thickness of unconsolidated deposits in feet.UNCONSOLIDATED_THICKNESS_250k_IGS_IN.SHP 是一款Esri线要素形状文件（Esri line shapefile），用于呈现印第安纳州未固结沉积物厚度的等值线分布。该数据集的厚度等值线以多段线（polyline）表示，等值距为50英尺，每条多段线均附带单一数值，用以表征未固结沉积物的估算厚度（单位：英尺）。
