FEMA HAZUS Data and Software

Overview | Data Availability and Access | Interactive Web Mapping | Specifications and Documentation

AlertThis version of HAZUS (1999) has been supersceeded by HAZUS-MH (2005).

HAZUS: Raleigh Beltline Area

Overview

The Federal Emergency Management Agency HAZUS (Hazards U.S.) application has been created for use in assessment of earthquake risk. HAZUS also incorporates data for multi-hazard exposure analysis (e.g, Q3 flood boundaries, hurricane storm surge areas, and inland wind decay model data). The HAZUS application is available as an add-on to ArcView or MapInfo (the Libraries holds the ArcView version). HAZUS comes bundled with a wide range of spatial and tabular data (e.g. square footage by census tract of building occupancy by use type). This data is available on the campus network. Some of the FEMA data can be viewed interactively online via Online Hazards Maps.


Data Availability and Access

The core HAZUS data is available nationwide, though only North Carolina data is available on the campus network, as indicated below. The supplemental data--including flood data, FEMA shelters, hurricane maps, elevation contours, roads, land use/land cover--is only available for North Carolina and resides on the campus network. The HAZUS application install disk and core data for other states can be requested from Data Services or are available on CD-ROM at the DH Hill Library reference desk under call number Ref GIS Cabinet QE535.2 S34 H39 1999.

Consult the HAZUS Users Manual Appendices for complete descriptions of core data layers. File sizes shown below are for North Carolina data only. Note that for core data layers .avl files (ArcView legend files) are available.

Supplemental Data (Holdings: North Carolina Only)

SLOSH Basin Maps (Hurricane Maps)
Outlines of the land areas expected to be inundated by hurricane surges. Maps are named according to the SLOSH Basin ID and the hurricane category they represent. Specifies the elevation of water above the National Geodetic Vertical Datum (NGVD) and not the depth of flooding. The surge value should be compared with ground elevation to determine flooding. Consult section 11.5 of the HAZUS technical documentation for details about basin coverage and file names. North Carolina files: Chp*.* = Chesapeake, Eht*.* = Pamlico Sound, ILm*.* = Wilmington.
