Completeness Commission
evaluation Method Description
Data contained in the Terrain package highlights specific issues in the Elevation datasets. Terrain data are derived datasets
that aid automated hydrologic and hydraulic analyses, the flood hazard area boundary delineations, and quality control.

ConceptualConsistency
measure Description
The Terrain data are consistent with the Elevation dataset. A comparison of profile plots with the flow vector data confirms
that flow vectors are correctly drawn. Flood hazard boundaries do not extend beyond the ExternalBoundary, if exists. FIRM
panels show the flood hazard area delineations where Island data are present.
