Capital Area Planning Council -GeoMap 2009 Work Order SAAB DRN bulkheads, seawalls, road/highway embankments, and selected manmade features that constrict or control the flow of water (e.g., curb lines). All mapping will be in accordance with FEMA Guidelines and Standards - Appendix - Section A.8.5 and as clearly discernable on the intensity imagery. Contour Generation Data source is bare earth data gridded at 10' spacing combined with 3D breaklines. Contours automatically generated, basic line strings and minimal editing of contours for aesthetics. All contour lines will have an elevation attribute and be formatted to the following database: FEA CODE Contour (Index) 51 Contour 52 (Intermediate) Breakline 99 OBJECTID ContourAnno X Bold No ELEVATION XXX. xx XXX.xx XXX. xx TextString Elev FontName FontSize Aerial 8 Italic Underline Vertical No No Alignment Bottom Contour Labels Automatically generated labels, minimal editing for aesthetics. Every fifth contour line will be designated an index line and contour labels will be automatically placed for each index contour. Intermediate contours will not be labeled. Projection. Datums, Units • Datum NAD83-93 horizontal, NAVD 88, State Plane South Central zone. Tiling Scheme Same as defined by client for LiDAR Data. Accuracy Requirements The accuracy of the contours is a derivative of the accuracy of the LiDAR dataset. At a 1.4m posting, two-foot contour interval will meet 1.2 foot vertical accuracy @ 95% confidence level for flat terrain.
