Resources: Texas Hazard Mitigation Package
(THMP):
An Internet-based GIS Data Distribution Tool
www.thmp.info
Project by Texas Geographic Society
Sub-grantee of the Texas Governor’s Division of Emergency Management
The purpose of this grant is to compile and deliver digital geographicdatasets that can be used by state and local hazard mitigation planners
in identifying potential natural hazards and assessing relative risk
Texas Hazard Mitigation Packagewww.thmp.info
THMP is a free, easy-to-use, online application to: Identify historical hazard occurrences
• actual hazard event locations
• summarized by county Identify hazard risk areas Display supplemental information (including Base Data) for hazard-
related data Determine relative vulnerability (to population and property value) Download hazard-related data for use in other GIS-based systems

Texas Hazard Mitigation Package
Summary:
Use THMP, online, to identify and provide necessary data and mapsfor mitigation plans and other related risk assessment activities
Use THMP, online, to access other resources related to hazardsand mitigation planning
Use THMP to download data into your own GIS/mapping systemsto support or initiate your specific projects
Use THMP to download data into HAZUS to supplement the map
Use THMP, online, for preliminary investigation of vulnerable areasto analyze in HAZUS
