DFIRM Panels

[Metadata] FEMA Flood Insurance Rate Map (FIRM) panel features for the State of Hawaii as of December 2025. Downloaded from the FEMA Map Service Center 12/29/25. For more information, please refer to summary metadata: https://files.hawaii.gov/dbedt/op/gis/data/s_fld_haz_firm_panels.pdf or contact Hawaii Statewide GIS Program, Office of Planning and Sustainable Development, State of Hawaii; PO Box 2359, Honolulu, HI 96804; [phone]; email: [e-mail]; Website: https://planning.hawaii.gov/gis. The National Flood Hazard Layer (NFHL) data incorporates all Flood Insurance Rate Map (FIRM) databases published by the Federal Emergency Management Agency (FEMA), and any Letters of Map Revision (LOMRs) that have been issued against those databases since their publication date. It is updated on a monthly basis. The FIRM Database is the digital, geospatial version of the flood hazard information shown on the published paper FIRMs. The FIRM Database depicts flood risk information and supporting data used to develop the risk data. The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual-chance flood event, and areas of minimal flood risk. The FIRM Database is derived from Flood Insurance Studies (FISs), previously published FIRMs, flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by FEMA. The NFHL is available as State or US Territory data sets. Each State or Territory data set consists of all FIRM Databases and corresponding LOMRs available on the publication date of the data set. The specification for the horizontal control of FIRM Databases is consistent with those required for mapping at a scale of 1:12,000.

国家洪水危险图层（NFHL）数据集整合了美国联邦紧急事务管理局（FEMA）发布的所有洪水保险费率图（FIRM）数据库，以及自这些数据库发布之日起针对其出具的所有地图修订函（LOMRs）。该数据集按月进行更新。
洪水保险费率图数据库（FIRM数据库）为纸质版洪水保险费率图所刊载洪水危险信息的数字地理空间版本，呈现了用于生成风险数据的洪水风险信息及配套支撑数据。其采用的核心风险分类包括：年超越概率1%的洪水事件、年超越概率0.2%的洪水事件，以及最低洪水风险区域。
FIRM数据库源自洪水保险研究报告（FISs）、此前发布的FIRM、为支持FIS及FIRM开展的洪水危险分析，以及可获取的最新测绘数据。上述洪水保险研究报告（FISs）及FIRM均由FEMA发布。
NFHL可按州或美国领地数据集的形式获取，每个州或领地数据集包含该数据集发布当日可获取的全部FIRM数据库及对应地图修订函（LOMRs）。
FIRM数据库的平面控制规范与1:12000比例尺测绘要求保持一致。
