资源简介:

The spatial location of the points in this feature class was determined from the study document. The locations are somewhat general and are only meant to guide users to the area of the study. Georeferencing of the plans within the study document was not performed. In general, points were placed at the furthest downstream design point and were always snapped to a hydrology line. In cases where the study did not specify the design point, the point was snapped to an intersection of the property boundary and a hydrology line along which a cross section was taken. In cases where the stream did not actually intersect the property, the point was placed near the furthest downstream cross section location.The attribute data for this feature class was compiled primarily from existing flood study feature classes developed by __________? and secondarily from study document itself.
