Name: Transect Lines (zoom in to make visible)

Display Field: TRAN_NO

Type: Feature Layer

Geometry Type: esriGeometryPolyline

Description: A spatial data set consisting of lines that depict the location that was used to provide representative information for the coastal flood models. Required when transect-based analyses were performed. Fields: TRAN_LN_ID: Primary key for table lookup. Assigned by table creator. TRAN_NO: Transect Number. Transect Number referenced to FIS report and printed FIRM panel. Each transect is normally numbered sequentially. CST_MDL_ID: Surge_Wave. Indicates the type of analysis that was performed. SETUP_DPTH: Wave Setup depth in feet. Indicates if additional wave setup was added to the stillwater. SIG_HT: Significant Wave Height. This is the wave height associated with the 1-percent-annual-chance storm event. It is the average height of the highest 1/3 of all waves. It is used in WHAFIS and RUNUP models. Normally shown in feet. SIG_PD: Significant Wave Period. This is the wave period associated with the 1-percent-annual-chance storm event. It is the time it takes for a wave of the significant wave height to pass a point. Normally shown in seconds. CON_HT: Controlling Wave Height. The controlling wave height value is 1.6 times the significant wave height. This field is populated when the significant wave height is available for the start of each transect. This field is not required if the significant wave height is not available for the start of each transect, and WHAFIS default values are used. MEAN_HT: Mean Wave Height. Average height of all waves. The mean wave height is 0.626 times the significant wave height. Normally shown in feet. MEAN_PD: Mean Wave Period. Average period of all waves. The mean wave period is 0.85 times the significant wave period. Normally shown in seconds. SHOWN_FIRM: Indicates if a transect line will be shown on a printed FIRM panel. XCOORD: X-Coordinate. The X-coordinate of the 0.0-foot elevation point along the transect. This point must fall on the transect and have the same horizontal datum of the subsequent DFIRM study. The coordinates must be entered using the same coordinate system intended for the DFIRM Database. Typically the 0.0-foot elevation point is represented in the S_Tsct_Basln spatial file. YCOORD: Y-Coordinate. The Y-coordinate of the 0.0-foot elevation point along the transect. This point must fall on the transect and have the same horizontal datum of the subsequent DFIRM study. The coordinates must be entered using the same coordinate system intended for the DFIRM Database. Typically the 0.0-foot elevation point is represented in the S_Tsct_Basln spatial file. HYDROID: Unique ID number for each transect that references modeling input and output files. COUNTY: Name of the County STATE: Name of the State
