ENVIRONMENT__FEMA__Profil_Basln
Location and attributes for profile baseline and stream centerline features for the Flood Risk Project area.
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The spatial entities representing the profile baseline are lines. Profile baselines are to be stored in Polyline ZM feature classes, storing both profile station values (M-values) and 1-percent-annual-chance water-surface elevations (Z-values) at cross sections, structures and other modeled inflection points.</SPAN></P><P><SPAN>For new models and effective models with valid profile baselines, vertices along the profile baseline are to be calibrated between cross sections and structures using linear referencing / dynamic segmentation tools in GIS. The first vertex of each profile baseline will be the downstream most point on the profile.</SPAN></P></DIV></DIV></DIV>
