F4100320001.TIF - FEMA Flood Insurance Rate Maps for the Seaside-Gearhart, Oregon, Area: Seaside 1

FEMA's Flood Insurance Rate Map (FIRM) depicts the spatial extent of Special Flood Hazard Areas (SFHAs) and other thematic features related to flood risk assessment. FIRMs also provide a basis for establishing flood insurance coverage premium rates offered through the National Flood Insurance Program (NFIP). These maps were published as paper documents, which have been scanned into image files (TIFF) as part of FEMA's FIRM modernization process. This is one of three scanned maps for the Seaside-Gearhart area - 410030 0001 D, 410032 0001 C, and 410032 0002 C - that were georeferenced for the probabilistic tsunami hazard assessment project.

美国联邦紧急事务管理局（Federal Emergency Management Agency, FEMA）的洪水保险费率地图（Flood Insurance Rate Map, FIRM）描绘了特殊洪水危险区域（Special Flood Hazard Areas, SFHAs）及其他与洪水风险评估相关的专题要素的空间分布范围。该地图同时为依托美国国家洪水保险计划（National Flood Insurance Program, NFIP）制定洪水保险承保费率提供了核心依据。此类地图最初以纸质文档形式发布，作为FEMA推进FIRM现代化改造项目的组成部分，已被扫描为TIFF格式的图像文件。本数据集为锡赛德-吉尔哈特（Seaside-Gearhart）区域的三份扫描地图之一，该批次地图均为概率性海啸灾害评估项目完成了地理配准，其余两份分别为410030 0001 D、410032 0001 C与410032 0002 C。
