What is RASPLOT?

RASPLOT is a computer program developed by FEMA which allows the user to create flood profiles through the automatic extraction of data from Hydraulic Engineering Centers River Analysis System (HEC-RAS) hydraulic modeling files. Flood profiles are required for inclusion in the Flood Insurance Study (FIS) reports which usually accompany the Flood Insurance Rate Map (FIRM) for communities participating in FEMA’s National Flood Insurance Program.                          


Common RASPLOT software users include:

  • FEMA Mapping Partners (mapping contractor staff and Cooperating Technical Partners)
  • Users responsible for preparing and delivering FIRMs and FIRM databases, FIS reports and related products to FEMA in support of its Risk MAP program
