<br />STANDARDS FOR DIGITAL LINE GRAPHS <br />FOR THE NATIONAL FLOOD INSURANCE PROGRAM: <br /> <br />ATTRIBUTE CODING <br /> <br />FLOOD HAZARD ZONES <br /> <br />Node Attribute Codes <br /> <br />None <br /> <br />Area Attribute Codes <br /> <br />Kajor Kinor <br />Code Code Descriptor <br /> <br />Comments <br /> <br />000 <br /> <br />0000 <br /> <br />Outside Area <br /> <br />Each DLG provides a coherent description of <br />that portion of the earth's surface covered <br />by a 1:24,OOO-scale, 7.5-minute cell. To <br />maintain topological consistency and to <br />facilitate the combination (integration) of <br />multiple DLGs, the area outside the cell is <br />specifically identified for each DLG. This <br />area element, which must be the first area <br />present in each data category, is assigned a <br />single attribute code with major and minor <br />codes both equal to zero. <br /> <br />440 <br /> <br />0150 <br /> <br />Zone V <br /> <br />This code identifies an area inundated <br />100-year flooding with velocity hazard <br />action); no BFEs have been determined. <br />shown by FIS symbol AI05. <br /> <br />by <br />(wave <br />It is <br /> <br />440 <br /> <br />0151 <br /> <br />Zone VE <br /> <br />This code identifies an area inundated by <br />100-year flooding with velocity hazard (wave <br />action); BFEs have been determined (parameter <br />code 441 0---) and are usually expressed in <br />feet (descriptive code 440 0610) but are <br />expressed in meters (descriptive code <br />440 0611) for some communities. It is shown <br />by FIS symbol AI06. <br /> <br />440 <br /> <br />0152 <br /> <br />Zone A <br /> <br />This code identifies an area inundated by <br />100-year flooding, for which no BFEs have <br />been determined. It is shown by Frs symbol <br />AIOO. <br /> <br />10193 <br /> <br />39 <br />
