Flood Map Modernization Introduction Accurate information about risks is the first step in preventing and reducing losses.

Flood Map Modernization Introduction To support the vision, “A Nation Prepared,” the Federal Emergency Management Agency (FEMA), has undertaken the Map Modernization effort to update the Nation’s flood hazard maps.

Flood Map Modernization Mapping Information Platform (MIP) What is the MIP? Web-Based Technology that Enables the Management, Extraction, Sharing, and Production of Map Modernization Data How Does it Help?  Proactive Centralized Project Management and Tracking  Standard Data Collection Search and Storage  Free Tools Available

Flood Map Modernization Identify Problem by Reviewing Project Summary and Reports 3 Perform task and update MIP 4 Tracking and Management Tool for Map Mod Over 1,290 Active Studies Over 20,000 MT-1s (LOMAs) Over 1,400 MT-2s (LOMRs) Over 20,000 Communities Over 60 Contractors Over 200 CTPs MIP

Flood Map Modernization MIP: Repository The geospatial platform will be the repository for the national GIS data layer and will store the following: Final Digital Flood Insurance Rate Map (DFIRM) data Intermediate data, including the outputs of key steps used to create the DFIRM data.  Scoping  Survey  Elevation  Hydrology and hydraulics modeling data  Base Flood Elevations (BFEs)  Flood outlines and other pertinent data

Flood Map Modernization Elevation Data Data Capture Standards NDEP/NDOP

Flood Map Modernization Purpose of Data Capture Standards  Provide a consistent framework for collection, storage, and retrieval of the data needed for a Flood Insurance Study (FIS)  Describe what needs to be captured from digital data that was used in the FIS  Capture key data required for model maintenance and quality control  Verify that the data can be accessed easily and used for other projects

Flood Map Modernization Survey Data

Flood Map Modernization Survey Data  Complete digital submission of all survey data files, photographs, sketches, and notes  Data specifications for surveyed cross sections and structures Cross sections Bridges Culverts Dams Elevation Reference Marks High water marks Levees

Flood Map Modernization Acceptable Data Formats  Database tables Microsoft Access 2000 dBase IV tables  Metadata  Photographs Portable Network Graphic (PNG) JPEG (JPG) Bitmap (BMP)  Sketches Adobe Acrobat (PDF) PNG JPG  Spatial files ESRI shapefiles Open GML format
